Introduction

VariTrane variable-air-volume (VAV) units lead the industry in quality and reliability and are

designed to meet the specific needs of today’s applications.This generation of VariTrane units

builds upon the history of quality and reliability and expands the products into the most complete

VAV offering in the industry.

Single-duct units provide an economical energy-savings system solution.This is the most

common type of VAV unit.

Dual-duct units have two air valves. One heating valve and one cooling air valve modulate

simultaneously to provide occupant comfort.These systems were popular prior to the energy crisis

of the early 1970s. Popularity is increasing with system concepts which use one valve for

maintaining vav definition in english monitoring 100% gyouel vav air.

Features and Benefits

Construction

UL-listed products—

Safety and reliability are vital in commercial construction. AllVariTrane units are completely listed

in accordance with UL -1995 as terminal units.This listing includes the VAV terminal with electric

heaters. Additionally, all insulation materials pass UL 25/50 smoke and flame safety standards.

AHRI Certified Performance—

All VariTrane units are AHRI certified. AHRI 880 guarantees the pressure drop, flow performance,

and acoustical performance provided is reliable and has been tested in accordance with industry

accepted standards. AHRI 885 uses AHRI 880 performance and applies accepted industry methods

to estimate expected “NC” sound levels within the occupied space.

Casing Design—

Interlocking Panels—VariTrane products are manufactured in the most state-of-the-artVAV facility

in the world.The patent-pending interlocking panels are designed using integral I-beam

construction technology.This limits deformation and creates tremendous product rigidity. An

additional benefit is a smooth unit exterior with few exposed screws—ideal for exposed ceiling

applications. VariTrane units are designed for use in systems that operate up to 5" w.c. of inlet

pressure.

Metal Encapsulated Edges—AllVariTrane units are complete

with encapsulated edges to arrest cut fibers and prevent

insulation erosion into the trane vav boxes with electric reheat is the standard of

care in applications concerned with fiberglass erosion or

projects with either double-wall or externally wrapped duct

work.

TheTrane Air Valve—is at the heart of VariTrane terminal

units.This is where airflow is measured and controlled.

Repeatability and ruggedness is vital.VariTrane products are

the most rugged and reliable available.

18-gage Cylinder—limits deformation or damage during shipment and job site handling, and

provides even airflow distribution across the flow ring for unmatched airflow measurement

accuracy.

ContinuouslyWelded Seam — an automated vav tour process creates the highest quality continuous

seam, which is “right” every time.The welded seam improves air valve rigidity and creates

consistent and repeatable airflow across the flow measurement device.The result is a truly round

cylinder every time, with no flat spots caused by lower quality crimping and riviting technologies.

6 VAV-PRC011-EN

Features and Benefits

Flow Ring—TheTrane flow ring is time tested to perform trane vav boxes with electric reheat the

most demanding conditions. Additionally,Trane’s patented flow ring

is recessed within the air valve cylinder to reduce the potential for

damage during job site handling and installation.

External Elif ve vav harfi ne anlama gelir simple design provides controller flexibility and is designed to facilitate

actuator field replacement.

Position Indicator—The position indicator shows current air valve position to aid in system

commissioning. Many times this vav definition in english be seen from the floor without climbing a ladder.

clutch access for simplified commissioning.

Indoor Air Quality (IAQ) Features

The oil embargo of the early 1970s created an energy crisis, which resulted in tighter vav definition in english, and

reduced ventilation rates. A fallout issue of tighter building construction was poor indoor air

quality.This heightened IAQ awareness. IAQ issues have been featured in publications from the

smallest towns to the largest cities. System design should consider applicable ventilation and IAQ

standards.(See your localTrane Sales Engineer or visit www.trane.com for additional

information). Good indoor air quality results from units and systems which:

• Provide the required amount of ventilation air to each zone during all operating conditions

• Limit particulates from entering trane vav boxes with electric reheat spaces

VariTrane units are designed with simplified access and a full line of insulation options including:

Matte-faced—Typical industry standard with reduced first cost.

Closed-cell—This insulation has an R-value and performance equivalent to matte-faced insulation.

The main difference is the reduction of water vapor transmission. Closed-cell is designed for use

in installations with a high chance of water formation. (It has been used to coat the exterior of chiller

evaporator barrels for many trane vav boxes with electric reheat />

Foil-faced—A fiberglass insulation with a thin aluminum coating on the air stream side to prevent

fibers from becoming airborne.The aluminum lining is acceptable for many applications, however

it is not as rugged as double-wall

Double-wall—Premium insulation often used in many health care applications with insulation

locked between metal liners.This eliminates the possibility for insulation entering the airstream

and allows for unit interior wipe-down as needed.

VariTrane VAV units are the most prepared IAQ units in the industry.The end result is a reliable

product designed for peak performance, regardless of job site conditions or handling.

Trane Integrated Comfort Systems (Controls Integration)

VariTrane units are designed to meet today’s electronic and pneumatic control system needs. An

Integrated Comfort System consists of units and controls that are:

• Pre-engineered to consistently integrate into your system “right out of the box.”

• Factory-Commissioned for assured installed performance with the highest level of quality and

reliability.

VAV-PRC011-EN 7

Features and Benefits

• Single-Sourced (controller and equipment) to provide the assurance that when you have

system questions, your localTrane Sales Office is your personal full-service provider for all your

comfort needs.

(Additional control options and sequence-of-operations are located in the “Controls” section.)

Trane DDC Controller

DDC (communicating electronic)—DDC

controllers are today’s industry standard. DDC

controllers provide system-level data used to

optimize overall SYSTEM performance.

Variables such as occupied/unoccupied,

minimum and maximum cfm and

temperature, valve position, ventilation

fraction, etc. are available on a simple twistedshielded

wire pair. For additional information,

see “Industry Issues: Energy Efficiency”.

Note:

One of many Trane DDC Control Options which are factory-installed, wired, calibrated, and fully tested before shipment.

Trane DDC controllers provideTrane-designed solid-state electronics intended specifically forVAV

temperature control in space comfort applications. DDC control capabilities include:

• Pressure-independent (PI) operation—Provides airflow required by the room thermostat to

maintain occupant comfort.The controller automatically adjusts valve position to maintain

required airflow. Minimum and maximum airflow is factory-set and field-adjustable.

• Factory-set airflow and temperature setpoints

• Most advanced system integration in the industry.

LonTalk Controllers

LonTalk Controller

Trane now offers a full line of LonTalk

controllers designed for simple integration

into ANY system which can communicate via

8 VAV-PRC011-EN

Features and Benefits

Pneumatic Controller

Pneumatic—Pneumatic controllers provide

proven reliability and performance. A full line

of options provide:

• Highest quality PVR available, which

maximizes zone temperature control.

Pressure-independent operation

• AllVariTrane pneumatic controllers use the

patented flow sensor input to provide the

most accurate performance available.

Binary Input Controller

Binary Input Controllers are system level

controllers design to communicate with the

VAV boxes via external binary inputs.This

non-programmable controller satisfies critical

requirements for systems that do not need the

full functionality of a true BuildingAutomation

System (BAS).

Integration Options (Interfacing with other control systems) -Trane offers three ways to

interface with other control systems.

1. UseTrane LonMark, factory-commissioned VAV controllers

2. Use theTrane Binary Input Controller (BIC).The BIC allows system control through binary logic.

This means that a control system on an existing campus, or those seeking "Analog noncommunicating

relays, etc.This can be a cost effective interface option where a fullTrane DDC VAV System is

not available.

3. UseTrane Trane vav boxes with electric reheat factory-commissioned VAV controllers.

Factory-installed vs. Factory-commissioned:

The terms factory-installed and factory-commissioned are often used interchangeably.Trane takes

great pride in being the industry leader in factory-commissioned DDC controllers. Table 1, p. 10

differentiates these concepts.

Factory-commissioned controllers provide the highest quality and most reliable units for yourVAV

system. Additional testing verifies proper unit avis vavida including occupied/unoccupied airflow,

temperature setpoints, communication link functionality, and output device functionality.The

benefits of factory-commissioning are standard on VariTrane terminal units withTrane DDC

controls.This means that factory-commissioned quality on VariTrane VAV units is now available

on ANY manufacturer’s control system that can communicate using the LonMark Space Comfort

Control (SCC) protocol. (See Controls section for complete listing of variables which are

communicated.)

VAV box during the construction phase. It is

utilized to seal all openings without

constraining the installation process.

Trane VAV Systems - Proven Performance

Trane is the industry leader in VAV systems, including factory-commissioned controls and

integration with other control systems.This leadership began with customers seeking the most

reliable VAV products in the industry.The solution was factory-commissioned controls (see

Factory-installed vs. Factory-commissioned). Since then, it has blossomed to include optimized

system control strategies.

Control strategies are often made more complicated than necessary. VariTrane DDC controls

simplify control strategies by pre-engineering control logic and sequencing into the controller.This

information is available via a twisted-shielded wire pair, and accessible via aTraneTracer Summit

building automation system. Data is easily accessed via a computer workstation.

Optimized system control strategies, such as ventilation optimization, fan-pressure optimization,

and optimal start/stop, are pre-engineered in VariTrane unit-level DDC controllers and theTracer

Summit building automation system.

This allows aTrane VAV system to meet or exceed the latest ASHRAE 90.1 Energy Efficiency

standards. Pre-engineered controls allow consistent, high quality installations which are very

repeatable.The end result is PROVEN control strategies you can rely on to perform. For more

information on these and other control strategies, contact your localTrane Sales Office, or visit

www.trane.com.

Purchasing VAV controllers and VAV hardware from a single manufacturer provides a single

contact for all HVAC system related questions.

Agency Certifications

There are numerous regulations and standards in the industry that determine the trane vav boxes with electric reheat and

performance parameters for VAV terminal units. Some of the more important of those standards

and regulations are listed below, along with a brief description of what each one addresses.

American Society of Heating, Refrigerating and Air-conditioning Engineers

(ASHRAE) - 41.1

ASHRAE - 41.2

ASHRAE - 41.3

These standards specify methods for temperature measurement (41.1), laboratory airflow

measurement (41.2), and pressure measurement (41.3).While none of these standards specifically

discusses VAV air terminals, they discuss topics that are aspects of terminal box systems.

Therefore, some engineers will include these standards in their specifications as a primer on

accepted measurement techniques.

ASHRAE - 62

This standard specifies the minimum ventilation rates and indoor air quality that are acceptable for

occupied spaces.

ASHRAE - 111

This standard calls out procedures to be followed for testing and balancing HVAC systems. It

includes descriptions of the equipment used, procedures followed, and field changes that must be

made when a system is balanced.

Air Conditioning and Refrigeration Institute (AHRI)

AHRI 880 - 2011

This standard sets forth classifications, performance testing requirements, and test results

reporting requirements for air terminal units.The standard contains very detailed procedures that

are to be followed for the testing and certification program associated with this standard.This is

one of the most commonly referenced standards in the VAV terminal unit industry.The AHRI-880

certification program is designed to police the accuracy of documented performance for terminal

units.The certification program requires a sampling of at least four units be tested annually.The

tested units are chosen at random by AHRI and sent to an independent laboratory for the testing.

The performance is tested at one specific operating condition.The operating characteristics tested

include discharge and radiated sound power (for the damper and, in the case of fan-powered

boxes, the fan), wide-open damper pressure drop, and fan motor amp draw. VariTrane terminal

units are certified according to AHRI-880.

AHRI 885-2008

This document provides a procedure to estimate sound pressure levels in an occupied space.The

standard accounts for the amount of sound pressure in the space due to the VAV air terminal,

diffusers and their connecting low pressure ductwork. While sound generated from the central

system fan and ductwork may be a significant factor in determining the sound pressure level in the

room, this standard does not address those factors. It focuses solely on theVAV terminal and items

downstream of it.This standard is related to AHRI-880 by using sound power determined using

AHRI-880 methodology as a starting point for the AHRI-885 procedure.

Underwriter’s Laboratory (UL) 1995

Underwriter’s Laboratory is an independent testing agency that examines products and

determines if those products meet safety requirements. Equipment manufacturers strive to meet

UL guidelines and obtain listing and classifications for their products because customers recognize

UL approval as a measure of a safely designed product. VariTrane VAV air terminals are listed

per UL-1995, Heating and Cooling Equipment.The terminals are listed as an entire assembly.

VAV-PRC011-EN 11

Agency Certifications

National Fire Protection Association

NFPA 70

This standard is also known as the National Electrical Code (NEC).The Code gives standards for

installation of wiring and electrical equipment for most types of commercial and residential

buildings. It is often referred to inVAV air terminal specifications when fan-powered boxes, electric

heat or electric controls are included.

NFPA 90A

This standard does not speak directly to VAV air terminals but does discuss central system

considerations pertaining to a fire and/or smoke condition.The standard discusses safety

requirements in design and construction that should be followed to keep the air-handling system

from spreading a fire or smoke.The standard specifies practices that are intended to stop fire and

smoke from spreading through a duct system, keep the fire-resistive properties of certain building

structures (fire walls, etc.) intact, and minimize fire ignition sources and combustible materials.

Single-Duct VAV Terminal Units

Selection Procedure

Air Valve Selection

The features of the single-duct VAV terminal vav definition in english are described by the product categories shown

in bold. Within each category the available options are listed.

This section describes the catalog selection of single-duct VAV terminal units with specific

examples. A computer selection program is also available trane vav boxes with electric reheat aid in selection ofVAV terminal units.

Selection of single-duct VAV terminal units can involve three elements:

• Air valve selection

• Heating coil selection (if required)

• Acoustics

The wide-open static pressure and airflows are found in the performance data section of the

catalog.To select an air valve, locate the required design cooling airflow for your terminal unit type

and find the smallest air valve size that has a pressure drop equal to or lower than the maximum

wide-open static pressure requirement.

Selection Example: Cooling Only VCCFTerminal Unit

Design cooling airflow: 1700 cfm

Maximum wide open Air pressure drop: 0.25 in. wg

Minimum cooling airflow: 850 cfm

From the performance data charts, select a valve size 12, which has a wide-open static pressure

drop of 0.01 in. wg

Check the minimum and maximum cfm desired with the minimum and maximum cfm allowed titus vav boxes with electric heat />

the table in the general data section.The maximum setting of 1700 cfm is within the acceptable

range.The desired minimum setting of 850 cfm is acceptable for the cooling only box desired. Note

that if an electric reheat box was selected, the minimum cfm would be dependent upon the kW of

the electric heater. (See Electric Heat Unit Selection.)

Heating Coil Selection (If required)

First, determine the amount of heat required to meet space and downstream duct heat losses from

a load calculation.

Hot Water Heat

Select a hot water coil sufficient to meet the design heat loss.

Example:

VCWF, Hot Water Unit Heat, Size 12 (See air Valve Selection)

Heating airflow: 850 cfm

Hot water flow: 1.0 gpm

Design Heat Loss: Q =25 MBh

Select hot water coil from the coil performance table in the Performance Data section of the catalog.

Selection:

A one-row coil is sufficient to meet design conditions. From the HotWater Coil Capacity Data of the

Performance Data Section, a one-row coil for a size 12 air valve will operate at the above conditions

as follows:

Coil Capacity: 25.17 MBh

Water pressure drop: 0.72 ft WPD

VAV-PRC011-EN 15

Single-Duct VAV Terminal Units

Selection Procedure

Acoustics

Air pressure drop (APD) of the hot water coil is included in the chart preceding the hot water coil

performance data section.

APD = 0.35 in. wg

Electric Heat

Determine the kW required to meet zone design heat loss.

kW=MBh / 3.414

MBh=Design Vava dash 4k Loss

Select the nearest available kW with voltage and steps desired from the electric heater kW guideline

table in the Performance Data section of the catalog.

Example:

VCEF, Electric Unit Heat, Size 12 (See Air Valve Selection)

Heating airflow: 850 cfm

Voltage: 277/60/1 VAC

Design Heat Loss: Q=25 MBh

kW=Q/3.414

kW=25/3.414

kW=7.3

Selection:

Select 7.5 kW from the electric heat table in the voltage and stages required.The table shows the

minimum cfm allowable for the kW selected.The static pressure requirement is shown as 0.06 in.

wg for this example with a design cooling flow of 1700 cfm.

Check Leaving AirTemperature:

LAT = ------------------------------------

Q

+ T

1.085 CFM

T is the primary entering air temperature 55°F hebrew words with double vav this example.

LAT = ----------------------------------

3414 7.5

+ 55=

82.8

1.085 850

Decide if leaving air temperature of 82.8°F is satisfactory for your application.

The acoustical data found in the "Performance Data" section of the VAV catalog is used to make a

determination of the amount of noise the terminal unit will generate. Locate the table for the VAV

terminal unit of interest. Sound power data and an equivalent NC level for an AHRI 885-2008

transfer function is listed.

Example:

VCCF, Cooling-OnlyTerminal Unit, Size 10 (See air Valve Selection)

Cooling Airflow: 1100 cfm

Maximum inlet static pressure: 1.5 in. wg

Interpolation gives sound power data of:

Octave Band 2 3 4 5 6 7 NC

Disch Sound Power 68 68 65 trane vav boxes with electric reheat 60 57 28

Rad Sound Power 63 58 54 47 39 32 29

The NC level above is determined by using either the catalog’s AHRI 885-2008 (mineral fiber trane vav boxes with electric reheat />

radiated sound) transfer function for the conditions shown in the acoustics table. A different

transfer function could be applied as conditions dictate.

Selection Procedure

Single-Duct VAV Terminal Units

General Data

The maximum NC level is NC-29. If the maximum NC level was exceeded, it would have been

necessary to reselect the next larger unit size.

Computer Selection

The advent of personal computers has served to automate many processes that were previously

repetitive and time-consuming. One of those tasks is the proper scheduling, sizing, and selection

of VAV terminal units.Trane has developed a computer program to perform these tasks.The

software is called theTrane Official Product Selection System (TOPSS).

TheTOPSS program will take the input specifications and trane vav boxes with electric reheat the properly sized VariTrane VAV

terminal unit along with the specific performance for that size unit.

The program has several required fields, denoted by red shading in theTOPSS screen, and many

other optional fields to meet the criteria you have. Required values include maximum and

minimum airflows, control type, and model. If selecting models with reheat, you will be required

to enter information to make vava k12 trane vav boxes with electric reheat also.The user is given the option to look at all the

information for one selection on one screen or as a schedule with the other VAV units on the job.

The user can select single-duct, dual-duct, and fan-powered VAV boxes with the program, as well

as most otherTrane products, allowing you to select all yourTrane equipment with one software

program.

The program will also calculate sound power data for the selected terminal unit.The user can enter

calculate acoustical data subject to default or user supplied sound attenuation data.

Schedule View

The program has many time-saving features such as: 1) Copy/Paste from spreadsheets like

Microsoft® Excel; 2) Easily arranged fields to match your schedule; and 3)Time-saving templates

to store default settings.

The user can also export the Schedule View to Excel to modify and put into a CAD drawing as a

schedule. Specific details regarding the program, its operation, and how to obtain a copy of it are

available from your localTrane sales office.

Thread: Trane Fan powered VAV box with electric heat not heating

I just happened to find a similar problem with one of my VAV Areas this morning. Several zones were 2-4 degrees F cool, and they were all served by the same air handler. All the zones on that AHU were affected. No VAV reheats were on at all. My boxes are Trane Model VCEF (single duct, non fan powered, electric heat). I realize that is a different model than yours, but I think the control strategy may be very similar. Especially in regards to the air handler. What I found was the supply air temperature sensor in the air handler had a poor connection to the board. It would show the supply air temp rising to about 89-90 degrees, for several minutes at a time. I'm not yet certain, but I suspect that when the controls saw that warm supply air it disabled the VAV reheat, with the belief that the warm air from the AHU would heat the space. And it may possibly be to protect the heat elements. When I repaired the sensor connection, the VAV reheats all came on and warmed the spaces to setpoint. The key to troubleshooting this elif ve vav harfi ne anlama gelir to look at what is common to all the boxes, as mentioned earlier by Rider77 and maybe others.

Also, Vava baby should add, there was no indication at either the Tracer workstation or the AHU controller as to whether the reheats were disabled, or why. They were simply shown to be off. I had to do some troubleshooting to find out why. It was from the workstation that I saw an abnormal supply temp. Especially with chilled water valve 100% open.

My VAV AHU's have no heat capability. All heat is from VAV reheats.

5 Selection Procedure Single and Dual-Duct This section describes the catalog selection of single and dual-duct VAV terminal units with specific examples. A computer selection program is also available to aid in selection of VAV terminal units, but is not described here. Selection of single and dual-duct VAV terminal units can involve three elements: 1. Air Valve selection 2. Heating coil selection (if required) 3. Acoustics Air Valve Selection The wide open static requirement pressure versus airflow curve is found in the performance data section of the catalog. To select an air valve, locate the required design cooling airflow for your terminal unit type and find its vertical intersection, with the smallest air valve size that has a pressure trane vav boxes with electric reheat equal to or lower than the maximum wide open static pressure requirement. Example: Cooling Only VCCE Terminal Unit Design cooling airflow: 1700 cfm Maximum wide open air pressure drop: 0.25 in. wg Minimum cooling airflow: 300 cfm From the performance data charts, select a valve size 17 which has a wide open static pressure drop of 0.16 in. wg. Check the minimum and maximum cfm desired with the minimum and maximum cfm allowed in the table in the general data section. The maximum setting of 1700 cfm vavosas .com within the acceptable range. The desired minimum setting of 300 cfm is acceptable for the cooling only box desired. Note that if an electric reheat box was selected, the minimum cfm would be dependent upon the kw of the electric heater. (See Electric Heat Unit Selection.) Heating Coil Selection (If required) First, determine the amount of heat required to meet space and downstream duct heat losses from a load calculation. Hot Water Heat Select a hot water coil sufficient to meet the design heat loss. Example: VCWE, Hot Water Unit Heat, Size 17 (See air Valve Selection) Design heating airflow: 850 cfm Hot water flow: 1.0 GPM Winter room design Temperature: T = 68 F Design Heat Loss MBh: Q = 25 Select hot water coil from the coil performance table in the Performance section of the catalog. Selection: A Standard Capacity coil is sufficient to meet design conditions. From the Hot Water Coil Capacity of the Performance Section, a standard capacity coil for a Size 17 air valve will operate at the above conditions as follows: Coil Capacity: 25.7 MBh Water pressure drop: 0.33 ft WPD Air pressure drop (APD) of the hot water coil is included in the chart preceding the hot water coil performance data section. APD = in. wg Electric Heat Determine the kw required to meet zone design heat loss. kw = MBh / MBh = Design Heat Loss Select nearest available kw with voltage and steps desired from the electric heater kw guideline table in the Performance section of the catalog. Example: VCEE, Electric Unit Heat, Size 17 (See Air Valve Selection) Design heating airflow: 850 cfm Minimum unit airflow: 300 cfm Voltage: 277/60/1 VAC Trane vav boxes with electric reheat room design temperature: T = 68 F Design Heat Loss: Q = 25 MBh kw = Q / kw = 25 / kw = 7.3 Selection: Select 7.5 kw from the electric heat table in the voltage and stages required. The table shows the minimum cfm allowable for the kw trane vav boxes with electric reheat. At 7.5 kw, the minimum allowable airflow is 510 cfm. The minimum cfm must be increased to 510 to assure adequate airflow over the 7.5 kw electric coil. The static pressure requirement is shown as 0.17 in. wg. for this example with a design cooling flow of 1700 cfm. Check Leaving Air Temperature Q LAT = + T x CFM Trane vav boxes with electric reheat if leaving air temperature of 95.8 F is satisfactory for your application. LAT = 3414 x = x 850 Acoustics The acoustical data found in the Performance section of the VAV catalog is used to make a determination of the amount of noise the terminal unit will generate. Locate the table for the VAV terminal unit of interest. Sound power data and an equivalent NC level for an ARI transfer function is listed. Example: VCCE, Cooling Only Terminal Unit, Size 17 (See air Valve Selection) Cooling Airflow Cfm = 1700 Maximum inlet static pressure: 1.5 in. wg. Downstream static pressure requirement: 0.30 in. wg. Maximum NC Criteria = NC-35 Maximum Inlet Static Pressure is the maximum static at the inlet to the box. Downstream Static Pressure requirement is the static loss downstream of the VAV box, which includes everything from the discharge of the box to the room. The catalog assumes 0.5 inches of downstream static pressure for all but the minimum inlet static pressure valves. Since we have a downstream static pressure loss of 0.30 inches, the static across the box will be more than the catalog s assumption using 0.5 inches downstream. Look into the catalog s acoustic table at ( ) or 1.7 inches. 57

6 Selection Procedure Single and Dual-Duct Interpolation gives sound power data of: Octave Band NC Rad. Sound Power Disch. Sound Power The NC level above is determined by using either the catalog s ARI transfer function for the conditions shown in the acoustics table. A different transfer function could be applied as conditions dictate. The maximum NC level is NC-26 which is less than the maximum NC for this example of NC-35. If the maximum NC level was exceeded, it would have trane vav boxes with electric reheat necessary to reselect the next larger air valve size. Computer selection of VAV terminal units greatly simplifies this task. 58

VAV electric reheat not working

MechEngNCPE(Mechanical)

(OP)

Hey guys, just got a call that the reheat coils for a job we did are not working (when thermostat set higher, heaters not kicking in). Now these are hold tight vav 8" titus single duct boxes with 2kw heaters. The heating cfm's range from 90-120cfm. I think that they are heating the vav definition in english too high and tripping a high limit cutout. I did the calcs and the 90 cfm minimum box would heat the air to 122 deg, when I want it around 95. I am thinking that they can adjust the minimum damper position for heating mode. Is this correct? I will bump the minimum up to around 200 cfm.

This of course trane vav boxes with electric reheat we check that the thermostats are hooked up and everything electrically is in order.

Am I right?

This section describes the catalog

selection of single-duct VAV terminal

units with specific examples. A

computer selection program is also

available to aid in selection of VAV

terminal units.

units can involve three elements:

• Air valve selection

• Heating coil selection (if required)

• Acoustics

Air Valve Selection

The wide-open static pressure and

airflows are found in the performance

data section of the catalog. To select an

air valve, locate the required design

cooling airflow for your terminal unit

type and find the smallest air valve size

that has a pressure drop equal to or

lower than the maximum wide-open

static pressure requirement.

Selection Example—

Cooling Only VCCF Terminal Unit

Design cooling airflow: 1700 cfm

Maximum wide open

Air pressure drop: 0.25 in. wg

Minimum cooling airflow: 850 cfm

From the performance data charts,

select a valve size 12, which has a wideopen

static pressure drop of 0.01 in. wg

Check the minimum and maximum cfm

desired with the minimum and

maximum cfm allowed in the table in

the general data section. The maximum

setting of 1700 cfm is within the

acceptable range. The desired minimum

setting of 850 cfm is acceptable for the

cooling only box desired. Note that if an

electric reheat box was selected, the

minimum cfm would be dependent

upon the kW of the electric heater. (See

Electric Heat Unit Selection.)

Heating Coil Selection (If

required)

First, determine the amount of heat

required to meet space and

downstream duct heat losses from a

load calculation.

Hot Water Heat

Select a hot water coil sufficient to meet

the design heat loss.

Example:

VCWF, Hot Water Unit Heat, Size 12

(See air Valve Selection)

Heating airflow: 850 cfm

Hot water flow: 1.0 gpm

Design Heat Loss: Q =25 MBh

SD 4

Single-Duct

Select hot water coil from the coil

performance table in the Performance

Data section of the catalog.

Selection:

A one-row coil is sufficient to meet

design conditions. From the Hot Water

Coil Capacity Data of the Performance

Data Section, a one-row coil for a size

12 air valve will operate at the above

conditions as elif ve vav harfi ne anlama gelir />

Coil Capacity: 25.17 MBh

Water pressure drop: 0.72 ft WPD

Air pressure drop (APD) of the hot

preceding the hot water coil

performance data section.

APD = 0.35 in. wg

Electric Heat

Determine the kW required to meet

zone design heat loss.

kW = MBh / 3.414

MBh = Design Heat Loss

Select the nearest available kW with

voltage and steps desired from the

electric heater kW guideline table in the

Performance Data section of the

catalog.

Example:

VCEF, Electric Unit Heat, Size 12

(See Air Valve Selection)

Heating airflow: 850 cfm

Voltage: 277/60/1 VAC

Design Heat Loss: Q = 25 MBh

kW = Q/3.414

kW = 25/3.414

kW = 7.3

Selection:

Select 7.5 kW from the electric heat

table in the voltage and stages

required. The table shows the

minimum cfm trane vav boxes with electric reheat for the kW

selected. The static pressure

requirement is shown as 0.06 in. wg

for this example with a design cooling

flow of 1700 cfm.

Check Leaving Air Temperature:

LAT = Q

+ T

1.085 x CFM

T is the primary entering air

temperature 55°F for this example.

LAT =

3414 x 7.5 + 55 = 82.8

1.085 x 850

Decide if leaving air temperature of

82.8°F is satisfactory for your

application.

Selection

Procedure

Acoustics

The acoustical data found in the

"Performance Data" section of the VAV

catalog is used to make a

determination of the amount of noise

the terminal unit will generate. Locate

the table for the VAV terminal unit of

interest. Sound power data and an

equivalent NC level for an ARI 885-98

transfer function is listed.

Example:

VCCF, Cooling-Only Terminal Unit, Size

10 (See air Valve Selection)

Cooling Airflow: 1100 cfm

Maximum inlet static

pressure: 1.5 in. wg

Interpolation gives sound power

data of:

Power

Rad. 63 58 54 47 39 32 29

Sound

Power

The NC level above is determined by

using either the catalog’s ARI 885-98

(mineral fiber for radiated sound)

transfer function for the conditions

shown in the acoustics table. A

different transfer function could be

applied as conditions dictate.

The maximum NC level is NC-37. If the

maximum NC level was exceeded, it

would have been necessary to reselect

the next larger unit size.

Computer Selection

The advent of personal computers has

served to automate many processes

that were previously repetitive and

time-consuming. One of those tasks is

the proper scheduling, sizing, and

selection of VAV terminal units. Trane

has developed a computer program to

perform these tasks. The software is

called the Trane Official Product

Selection System (TOPSS).

The TOPSS program will take the input

specifications and output the elif ve vav harfi ne anlama gelir />

sized VariTrane VAV terminal unit along

with the specific performance for that

size unit.

The program has several required

fields, denoted by red shading in the

TOPSS screen, and many other

optional fields to meet the criteria you

have. Required values include

maximum and minimum airflows,

control type, and model. If selecting

models with reheat, you will be

required to enter information to make

VAV-PRC008-EN

that selection also. The user is given

the option to look at all the information

for one selection on one screen or as a

schedule with the other VAV units on

the job.

The user can select single-duct, dualduct,

and fan-powered VAV boxes with

the program, as trane vav boxes with electric reheat as most other

Trane products, allowing you to select

all your Trane equipment with one

software program.

The program will also calculate sound

power data trane vav boxes with electric reheat the selected terminal

unit. The user can enter a maximum

individual sound level for each octave

band or a maximum NC value. The

program will calculate acoustical trane vav boxes with electric reheat />

subject to default or user supplied

sound attenuation data.

Procedure

Schedule View

The program has many time-saving features such as:

• Copy/Paste from spreadsheets like Microsoft ® Excel

• Easily arranged fields to match your schedule

• Time-saving templates to store default settings

The user can also export the Schedule View to Excel to modify and put into a CAD

drawing as a schedule.

Specific details regarding the program, its operation, and how to obtain a copy of it

are available from your local Trane sales office.

VCEF Electric Coil kW Guidelines – Minimum to Maximum

Minimum Circuit Ampacity (MCA) Equation

— MCA = heater amps x 1.25

Maximum Overcurrent Protection (MOP) Equation

— MOP = heater amps

— However since MOP ≤ MCA, then choose next fuse greater than MCA.

— Units without electric reheat would use smallest fuse sizing.

— Standard Fuse Sizes: 15, 20, 25, 30, 35, 40, 45, 50, and 60.

Example–For MOP of Single-Duct Unit

A model VCEF, electric reheat unit size 14 has 480/3 phase 15 kW electric reheat with 2 stages.

15 kW – 480/3 heater 15 x 1000 = 18.06

480 x 1.73

MCA = 18.06 x 1.25 = 22.58 amps. Since MOP ≤ MCA, then MOP = 25.

Useful formulas:

WARNING

must also be adhered to for responsible management of

refrigerants. Know the applicable laws and follow them.

WARNING
Proper Field Wiring and Grounding
Required!
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements for
field wiring installation and grounding as described in
NEC and your local/state electrical codes. Failure to
follow code could result in death or serious injury.

WARNING
Personal Protective Equipment (PPE)
Required!
Installing/servicing this unit could result in exposure to
electrical, mechanical and chemical hazards.

Before installing/servicing this unit, technicians

MUST put on all Personal Protective Equipment (PPE)
recommended for the work being undertaken.
ALWAYS refer to appropriate MSDS sheets and OSHA
guidelines for proper PPE.

When working with or around hazardous chemicals,

ALWAYS refer to the appropriate MSDS sheets and
OSHA guidelines for information on allowable
personal exposure levels, proper respiratory
protection and handling recommendations.

If there is a risk of arc or flash, technicians MUST put

on all Personal Protective Equipment (PPE) in
accordance with NFPA 70E or other country-specific
requirements for arc flash protection, PRIOR to
servicing the unit.

Important
Environmental Concerns!
Scientific research has shown that certain man-made
chemicals can affect the earths naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment.Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
such as HCFCs and HFCs.

Responsible Refrigerant Practices!

Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified.The Federal Clean Air Act
(Section 608) sets forth the requirements for handling,
reclaiming, recovering and recycling of certain
refrigerants and the equipment that is used in these
service procedures. In addition, some states or
municipalities may have additional requirements that

Failure to follow recommendations could result in death

or serious injury.

WARNING
Fiberglass Wool!
Product contains fiberglass wool. Disturbing the
insulation in this product during installation,
maintenance or repair will expose you to airborne
particles of glass wool fibers and ceramic fibers known
to the state of California to cause cancer through
inhalation. Glass wool fibers could result in respiratory,
skin or eye irritation.

Single-Duct Units

Figure 3.

Typical single duct unit VCEF

The basic unit consists of a sheet metal casing with an air

valve, which is used to modulate the air being delivered
into the occupied zone.The unit is designed to modulate
either cooling or trane vav boxes with electric reheat air between the temperatures of
40F and 140F. Air enters the air valve through the round
or rectangular inlet and exits into the sheet metal casing to
be distributed to the zone either through integral round
outlets in the casing or through rectangular duct attached
to the discharge of the unit.
The basic unit can also be ordered with factory-mounted
electric or hot water heating coils attached to the
discharge. See Figure 2, p. 10.
These re-heat units are used primarily to reheat air-to-zone
temperature when the load in the occupied space is low.

Dual-Duct Units

Primary air is modulated through theVariTrane air valve by

rotating the damper blade. All air valves have a round/
rectangular inlet for easy fit-up with incoming duct work.

Dual-duct units provide two air valves: one as heating

primary air and the other as cooling primary air. Both
discharge into the common outlet, which leads to the zone
being controlled. See Figure 4, p. 10.

Typical Single-Duct Units

Figure 1.

Typical single duct unit VCCF

Units are provided with a slip and drive rectangular duct

connection or can be ordered with trane vav boxes with electric reheat outlet plenum.
Sequencing of hot and cold air valve is dependent on job
requirements. One typical control is valves working in
conjunction to respond to zone temperature.
When the cooling valve becomes fully closed or reaches a
specified minimum, the heating valve will begin to
modulate or vice versa.The typical result is that air flowing
to the zone vav definition in english from maximum down to a minimum and
back up to maximum as load varies and controls would
cause one air valve to close and the other to open.

Figure 2.

Typical single duct unit VCWF

Another typical application is when the unit provides a

constant volume to the zone. When the zone sensor is tied
directly to the heating valve, it will modulate the heating
valve according to the zone temperature.
When the heating valve is fully closed or there is a call for
cooling in the zone, the cooling valve will be at constant
supply. As the space becomes too cool, the heating valve
will modulate open, decreasing the cooling valve flow.The
typical result is that the air flowing into vav definition in english zone stays at a
constant trane vav boxes with electric reheat whether the unit is heating or cooling.

Fan-Powered and Fan-Powered LowHeight Units

Figure 8.

Low height parallel: LPWF (top) & low height

parallel: LPEF (bottom)

VariTrane fan-powered and low-height fan-powered units

can be either parallel or series, with or without re-heat.
(SeeFigure 5, p. 11 thru Figure 8, p. 11.)

Typical Fan-Powered Units

Figure 5.

Parallel fan-powered terminal unit (top) &

series fan-powered terminal units (bottom)

The fan trane vav boxes with electric reheat a series unit runs continuously whenever the

main air handler unit is in operation.There are various
options for starting the fan.The fan can be started three
ways: 1) remotely, 2) by a duct pressure switch, or 3) by a
combination of both.The particular fan control method
may vary from unit to unit, depending upon job needs.

Figure 6.

Low height series: LSCF (top) & low height

series: LSWF (bottom)

Typically, heater is off while air valve modulates primary

air and responds to zone temperature. If zone temperature
decreases to the point where a decrease in primary air will
not maintain the desired temperature, the re-heat will be
activated to increase the temperature of the discharge air.
On a parallel unit, the VariTrane air valve delivers primary
cooling air to the unit outlet. When the space temperature
decreases beyond air valve control, the fan is turned on as
the first stage of heat.The fan delivers plenum air from
above the occupied space to the unit outlet, which is mixed
with primary air and delivered to the occupied space.
Note: Either the fan, the air valve, or both can deliver
airflow into the occupied space. In order to prevent
primary airflow from exiting through the fan when
the fan is not running on a parallel unit, a back draft
damper is provided. When the fan is not running,
the efficiency of this system is the same as a
standard single-duct VAV unit.

Figure 7.

Low height series: LSEF (top) & low height

parallel: LPCF (bottom)

Typically, the control systems applied to parallel units

cause the air valve to close to zero or a minimum flow
before the fan is activated. After the fan is activated, the
optional heat will be activated upon further reduction in
zone temperature.Therefore, minimal primary air is mixed
with the heated air.
VariTrane fan-powered unit fan sizes 02SQ05SQ and
08SQ10SQ were performance tested at .12 in. w.g. and
sizes 06SQ and 07SQ were tested at .15 in. w.g. Units are
not designed to operate unducted and below these tested
static pressures.
Note: Fan-powered units are available with rectangular
discharge connection only.The optional heater is
mounted on the discharge of the unit. Hot water
coils are connected to either the plenum inlet or on
the discharge on parallel units, and to the discharge
of series units.

WARNING
Proper Structural Support Required!

Figure 10.

Dual-duct hanger bracket locations

Ceiling structure must be strong enough to support the

weight of the unit. If unsure, check with a structural
engineer. Refer toTable 1, p. 22 thruTable 6, p. 24 for unit
weights. Failure to ensure proper structural ceiling
support could result in unit failing from its location
which could result in death or serious injury.

AIR
VALVE

COOLING

HEATING

Due to their weight, trane vav boxes with electric reheat VAV terminal units should be

suspended from the uppermost ceiling, independent of
the false ceiling grid. Suspension devices are to be
supplied by the installer. Units must be installed level and
upright. Failure to level the unit properly may prevent
proper operation of the controls and/or terminal unit.
Units are not designed to be installed vertically.
Consequently, this will also void the UL ratings and any
warranty on the unit.

Fan-Powered (Standard and Low-Height)

Fan-powered units should be supported by either hanger
straps or by using a threaded rod in conjunction with the
hanger brackets that are provided on the unit. Care should
be exercised to insure that the hanging straps do not block
the side access panel. See Figure 11, p. 15 thru Figure 18,
p. 21.

Duct Connections
All VariTrane units should be provided with a minimum of
1.5-duct diameters of straight duct prior to the inlet of the
unit. It is recommended that at least 48 inches of straight
duct be provided from the trane vav boxes with electric reheat of the units prior to
any take-offs or transitions.
Depending upon the size and weight of the single-duct
unit, it may be capable of being supported by the ductwork
that is connected to it. No hanger brackets are provided on
these units since the unit should be supported by means
of a hanger strap.The hanger strap should be secured
directly to the unit casing as shown in Figure 9, p. 12.
For cooling only single-duct units or single-duct units with
hot water coil, the unit may be rotated 180 for opposite
side connections.
For units with electric heat, the unit must be ordered from
the factory designating either right- or left-hand
connections

Dual-Duct
Dual-duct units should be supported by either hanger
straps trane vav boxes with electric reheat by using a threaded rod in conjunction with the
hanger brackets that are provided on the unit. See
Figure 10, p. 12.

Important: This is a requirement for trane vav boxes with electric reheat heat fanpowered units used in applications with
100% downward discharge.
Note: In order to x ray & vav rise the UL rating for VariTrane
electric coils, there must be four feet of straight
unlined ductwork downstream of the reheat coil
prior to any diffuser takeoffs.
1. After all connections are made, check that the entire
ductwork system is airtight. In some high-pressure
systems, duct sealer may be necessary.
2. Provide insulation around the entire inlet collar (all the
way to the unit casing).
Note: Use caution not to damage the flow tubes when
making ductwork connections or insulating.
3. Cut slits in the insulation for the flow tubes and
secure with duct tape.

VAV-SVX08D-EN

Unit Installation
4. If the unit is to be installed in a location with high
humidity, external insulation around the heating coil
should be installed as required.

Fan-powered VAV units have a plenum inlet that must

be clear of obstructions. Allow at least 36 of clearance
in front of the side access and plenum opening.

Water Coil Connections

Low-height fan-powered terminals require the same

plenum clearance requirement that applies to the
standard fan-powered units. However the access to the
internal components is located on the bottom of the
unit.

Note: The following coils have 3/8 OD water coil piping

connections.
Single Duct 1-row coils (inlet sizes 05, 05, 06, 08
or 10 only)
Low Height Parallel Inlet 1-row
Low Height Parallel Discharge 1-row
All others require a 7/8 OD water coil piping connections.
Note:
1. If necessary, you can change the coil connection from
left-handed to right-handed (and vice-versa) by
disconnecting the coil from the unit and rotating the
coil like a steering wheel 180.
Note: Exception - Coil connection cannot be changed
on parallel fan powered unit with hot water coil
on plenum trane vav boxes with electric reheat. On single row coils, the water inlet should elif ve vav harfi ne anlama gelir be on
the bottom and the outlet on the top. On vav definition in english, always plumb in the counter flow orientation:
Left-hand trane vav boxes with electric reheat water inlet on trane vav boxes with electric reheat bottom and
outlet on the top.
Right-hand units water inlet on the top and
outlet on the bottom.
3. Care should be taken to properly support the water coil
piping connections while connecting the adjoining
pipe.

It is also recommended that 6 of clearance be provided to

the top and bottom of all the units.
Note: The minimum clearance for controls and heater
controls should be 36 for all models except units
with 575-volt electric heaters, which require 48 of
clearance. NEC and/or local codes override all
clearance requirements.

Actuator Mounting
Important: When installing or replacing the actuator
tighten the actuator set screw per the
manufacturers instructions. Failure to
follow the manufacturers specifications
may result in unit malfunction.
Trane offers a factory-mounted actuator with a 90-second
drive time.The actuator drives 1 degree per second. A
field-installed actuator may be used if desired.The
actuator shaft has a -inch diameter and is designed to
travel clockwise to close the damper and counterclockwise to open the damper.There is an indicator on the
end of the actuator shaft that can be used to determine the
position of the damper.

Stand Alone UCM 4.2

Single-duct and dual-duct units provided with hot

water reheat have an access panel located on the side
of the water coil. All other single-duct and dual-duct
units are provided without access, as all functioning
components are external to the unit.

Fan-powered terminals are provided with a sliding side

access.

When there is no communication to the UCM control and

the unit is in the stand alone mode the control action vavá by the auxiliary temperature sensor located
onTB3-5 andTB3-6 terminals on the UCM board. In order
for the auxiliary sensor to determine the control action
(heat, cool) it must be located in the supply duct.The
auxiliary temperature is then compared to the zone
temperature. If the supply air temperature is 10 degrees
above the zone temperature, then the control action will be
heat. If the supply air temperature is less than or equal to
the zone temperature, then the control action will be cool.
If the supply air temperature is between the zone
temperature and the zone temperature + 10F (5.5C)(zone
temperature < supply air temperature < zone temperature
+ 10F) (5.5C), the control action remains the same and the
UCM trane vav boxes with electric reheat to the minimum flow set point. If an
auxiliary sensor is not installed the UCM will retain the last
control action in effect.

Low-height terminal units have a removable bottom

panel.

4. It is recommended that piping to the water trane vav boxes with electric reheat should

be done after field-mounted controls, external
insulation, and ductwork vava charger have been
completed.
Important:

Do not connect water valve or pipe

extensions to the water coil connections
unless supported.

(SCR) Motor Speed Control Adjustment

Procedure.
In order to make units more convenient and efficient to
balance, an SCR (silicone control rectifier) is provided as
standard on all fan-powered units.
The SCR is located on the side of the fan control box.To
adjust the speed of the motor, the external knob must be
rotated either clockwise trane vav boxes with electric reheat counterclockwise depending
on the desired speed adjustment.
There is an internal potentiometer (Figure 22, p. 26)
setting on the SCR controller that can be accessed by
removing the control box cover.This internal
potentiometer is set at the factory to the specific motor
voltage.

Figure 23. ECM control board

Trane offers an energy efficient ECM motor as a motor

option. Balancing of an ECM motor is accomplished
through electronic control adjustments on the ECM
control board (see Figure 23, p. 26). Potentiometer
settings for a multitude of CFM settings are given in
Table 9, p. 27 thru Table 21, p. 39. Other potentiometer
settings can be determined either by interpolating from
these tables or by using the following equation:
CFMsetting = CFMmin + {(Potentiometer Setting) x
[(CFMmax - CFMmin)/100]}
There is an LED on the ECM control board, which will blink
one time for every 100 CFM of motor setting. For example,
the LED on a unit set for 790 CFM will blink 7 times.The
LED on a unit set for 800 CFM will blink 8 times.
Note: This feature only verifies that the CFM is set
properly.This feature does not indicate at what
speed the motor is actually running.
The ECM must be load tested. In other words, the fan
must be connected to properly test the ECM.

It may be necessary to adjust this in the trane vav boxes with electric reheat depending on

the buildings power factor.

Maintenance
Periodic maintenance of theVariTrane product is minimal,
but necessary for efficient operation. Routine
maintenance consists of inspecting/replacing the air filters
of the fan-powered terminals.

Figure 32. Standard motor removal

Motors
Both the PSC (permanent split capacitor) and the ECM
(Electrically Commutated Motor) require no lubrication
during its normal life of operation.

Fan Wheel
Periodically, the fan wheel should be inspected for dirt or
debris and cleaned as necessary.

Filter
The filter on fan-powered terminals will need to be
inspected/replaced routinely depending on the
environmental conditions of the plenum.

Filter Change Out

To remove the filter, turn each of the filter retaining

clips 90 (CW or CCW)

Remove the filter and replace with new filter of the

same frame size.

Return the filter clips to their retainng position by

turning them 90 trane vav boxes with electric reheat or CCW) back to their original
position.

Water Coil

Standard height fan-powered series and parallel fan

motors are replaceable through the filter opening and the
standard sliding side access panel.To access the fan
motor, the fan housing must be detached by removing the
mounting bolts that trane vav boxes with electric reheat the housing to the fan board.
Removing the entire housing allows the fan motor, fan
housing, and fan wheel to be re-aligned on a workbench or
floor and prevent any possible fan wheel rubbing that may
occur. Removing the housing will provide access to the
motor shaft set screw that holds the fan wheel to the motor
shaft.

Water coils should be inspected and the fins should be

cleaned periodically.
Water coils have been provided with an access panel as
standard to assist with inspection and cleaning.

Fan Motor Replacement

WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturers
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect power
and discharge capacitors before servicing could result
in death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN.

VAV-SVX08D-EN

Maintenance

The low-height fan assembly was designed with an inlet

ring that assists with removal of the fan motor.To access
the fan motor assembly, the bottom panel must be
removed.The inlet ring is held in place by six bolts and
three motor mount bolts. Remove these bolts and the
motor and fan wheel will come out of the fan housing.

Figure 34. Typical heat sink fin orientation

Figure 33. Low-height motor removal

Bottom View

Every Master or Master/Slave relay combination is

mounted on a heat sink to prevent the relays from
overheating during normal operation.The SCR assembly
must always be mounted with the heat sink fins oriented
vertically (See Figure 34, p. 49), with a minimum clearance
of " on all sides of the heat sink for cooling. Where
additional cooling slots are provided in the heater, theVAV
unit must be mounted with a minimum of 1" clearance in
front of the slots.

SCR Assembly

When the 0-10VDC control voltage is present at the Master

relay in both single and three phase applications, an "ON"
indicating LED light on the Master relay will blink
continually (approximately 0.5 seconds on, 1.0 seconds
off). If the load side voltage is also present at the relay(s),
the Master relay LED and the Slave relay LED blink rate will
increase as the control signal increases. When the control
signal reaches a maximum of 10VDC, all LEDs will be lit
continuously, indicating that the relays are full-open and
continuously conducting. If the control signal is present in
three phase applications while the load side voltage is not,
only the Master relay LED will light and the blink rate will
be constant.

SCR solid state relays are used to switch a single heater

stage on and off. An intelligent (Master) relay is used for all
single phase applications. For three phase applications, a
Master-Slave configuration is used to switch two legs of
three phase power to the heater stage.The Master Relay
controls one leg independently, and provides a control
signal to the Slave Relay, which controls the second leg.

If the SCR assembly does not appear to be functioning

properly, verify that all required voltages are present and
all that all wiring is trane vav boxes with electric reheat connected. If all these
conditions are verified, and the SCR LED(s) does not light
and/or the SCR relay(s) does not conduct, the entire SCR
heat sink assembly should be changed out. Individual
Master elif ve vav harfi ne anlama gelir Slave relays should not be replaced.

VAV-SVX08D-EN

Installation of Diffusers
General

Concealed Spline Ceiling

All units must be installed upright and level as indicated by

the arrow on the side of the units. Return air slots should
be placed perpendicular and offset to the slot diffusers to
avoid short-circuiting of air distribution patterns.

Follow these procedures to finish installation of control

and satellite diffusers and concealed spline for suspension
ceilings before completing the ceiling construction
(Figure 36, p. 50).

Place the unit in its approximate final position and check

that it is upright and level. For single-slot units, engage
the back of the diffuser over the t-bar with an edge and
both ends resting on the t-bar. For double-slot units,
slide the unit over the t-bar. For center-notch units, place
diffuser over the t-bar, straddling it across a t-bar and
resting on the units ends.

Place the units in their approximate final positions. If using

the trim angle diffuser, its slots must be even with the
spline level. If applying the trim accessory, the bottom of
the diffuser must be level with the finished ceiling.

If the unit has a fire damper, make sure that the damper is
still fully open. Diffuser discharge must always be flush
