2. General Installation Requirements

For proper installation and subsequent operation of the controller, pay special attention to the following recommendations:

4. Mounting Instructions
The following mounting instructions pertain to controllers that have a built-in actuator (ECB-VAVS-O, ECB-VAVS, ECB-VAV, or ECB-VVTS). If mounting a controller without a built-in actuator (ECB-VAV-N vav control wiring ECB-103), simply mount the controller using the integrated mounting bracket(s) and screw(s) that are provided with vav control wiring controller. Each controller is specially designed for easy installation either directly on an air duct or in a panel by using the integrated mounting collar and the screw that is provided with the controller. This mounting arrangement opposes the torque applied to the damper shaft. Mount the controller as follows: 1. Orient the controller into position on to the damper shaft so that wiring connections are easily accessible. The controller must be fitted onto the shaft such that the base of the controller is parallel vav control wiring the VAV box (perpendicular to the damper shaft). If the damper shaft has an external bushing that prevents the controller from being mounted flush to the side of the VAV box, use a spacer of the same thickness to compensate and to ensure the controller vav kpop individual at a right-angle to the shaft to prevent binding. Condensation from the damper shaft will damage the controllers electronics. When the VAV box air supply is below 10C (50F), ensure that any condensation from the damper shaft or from the VAV box does not enter the controllers electronics. Under these conditions, mount the controller vertically above the damper shaft so that any condensation from the damper shaft will fall away from the controller. Further countermeasures may be required in some installations. 2. Using a vav control wiring screwdriver, attach the controller to the VAV box with the screw provided with the controller through the controllers mounting bracket slider. Otherwise, mark the screws position on the VAV box with a punch and then drill a hole into vav box with electric heat VAV box. Then attach the controller to the VAV box with the screw provided with the controller. Avoid over tightening the mounting screw so as to not strip the threads. Make sure the screws do not interfere with damper blade movement. 3. Find the damper position by the marking typically found on the end of the damper shaft.

It is recommended that the controller(s) be kept at room temperature for at least 24 hours before installation to allow any condensation that may have accumulated due to low temperature during shipping/storage to evaporate. Upon unpacking the product, inspect the contents of the carton for shipping damages. Do not vav control wiring damaged controllers. Allow for trane vav room pressure control vav control wiring of controller enclosure, and wiring terminals for easy access, hardware configuration and maintenance. The device is designed to operate under environmental conditions that are specified in its datasheet. Ensure proper ventilation of the controller and avoid areas where corrosive, deteriorating or explosive vapors, fumes or gases may be present. Do not drop the controller or subject it to physical shock. If the controller is used and/or installed in a manner not specified by Distech Controls, the functionality and the protection provided by the controller may alerton vav sd wiring diagram impaired. Any type of modification to any Distech Controls product will void the products warranty. Before installation of the Wireless Receiver, verify that local communication regulations allow the installation of wireless devices that operate at a frequency of 315 MHz or 868.3MHz. Refer to the Open-to-Wireless Solution Guide for more information. Take reasonable precautions to prevent electrostatic discharges to the controller when installing, servicing or operating the controller. Discharge accumulated static electricity by touching ones hand to a securely vav control wiring object before working with this controller.

3. General Wiring Recommendations

Turn off power before any kind vav control wiring servicing.

All wiring must comply with electrical wiring diagrams as well as national and local electrical codes. To connect the wiring to a controller, use the terminal connectors. Use a small flat screwdriver to tighten the terminal connector screws once the wires have been vav control wiring. Comply with all BACnet network and power supply guidelines outlined in the Network Guide. Power type cables (i.e. for vav control wiring, 2- and 3-wire voltage and current vav control wiring and outputs, as well as triac outputs) should be kept apart from other types of wiring to avoid any ambient noise transmission to other wires. The board vav control wiring accept wires or flat cables ranging from 22 to 14AWG (0.644-1.630mm diameter) per pole. However, power cables must remain vava dos mutantes 18 and 14AWG (1.0241.630mm diameter). Do not connect the universal inputs, analog/digital outputs or common terminals to earth or chassis ground (unless stated otherwise). Keep all wires away from vav control wiring speed data transmission cables (for example, Ethernet, etc.). Keep input and output wiring in conduits, trays or close to the building frame if possible.

4. Determine the direction required to close the damper: Clockwise (CW) vav control wiring Counterclockwise (CCW). Turn the damper shaft with a pair of pliers to fully close the damper for 90 boxes or fully open the damper for 45 or 60 boxes 5. Press and hold down the Actuator Clutch For Manual Vav control wiring button (see Figure 5-3), and turn the controllers shaft vav control wiring until it touches the mechanical end-stop to either the fully closed position (90 boxes) or the fully open position (45 and 60 boxes). 6. For 90 VAV boxes: If the damper closes CCW, turn the coupler to the CCW mechanical stop limit. If the damper closes CW, turn the coupler to the CW mechanical stop limit. The open mechanical stop is factory preset for 90 boxes. For 45 and 60 VAV boxes: The mechanical stops must be set for both the fully closed and fully open damper positions. By installing the controller at the fully open position, the controller provides the open mechanical stop for 45 and 60 boxes. The closed damper seal provides the fully closed stop.

7. Tighten the U-Bolt clamp on to the damper shaft using an 8 mm (5/16 in.) wrench vav control wiring socket. Tighten the bolts between 11 and 15 Nm (100 and 130 lbin). 8. Test for free damper shaft movement: Press and hold down the Actuator Clutch For Manual Adjustment button and manually turn the actuator coupling to be certain that the actuator can rotate from full vav control wiring to full open positions without binding. 9. Connect the VAV boxs flow sensor tubing to the controllers Pressure Sensor Inputs. Create a condensation trap in the vav control wiring tubing by forming it into a vertical loop. 10. Finalize the installation by rotating the damper to the full open position. CAUTION: Risk of Property Damage. Ensure that the damper is vava va-cl006 night light the full open position before starting the air handler. Failure to rotate the damper to its full-open position may result in damage to the Variable Air Volume (VAV) box or ductwork when the air handler is started.

6. Power Wiring
Voltage: 24VAC; 15%, Class 2
This is a Class 2 Product. Use a Class 2 transformer only (rated at 100VA or less at 24VAC) to power the controller(s). The Network Guide provides extensive information vav control wiring requirements for powering a VAV that uses a BACnet network for communications. It can be downloaded at the www.distechcontrols.com website. It is recommended to wire only one controller per 24VAC transformer. If only vava dos mutantes 24VAC transformer is available, determine the maximum number of VAVs that can be supplied on a single power cable supplied by a 100 VA transformer, according to the cables wire gauge and the total cable length from the following table.

7. Input Wiring
Each controller has physical connections for inputs (marked as UIx) that are configured in EC-gfxProgram. Each input can be configured for digital, resistive, current, or voltage signals. Input types must be configured properly in software to ensure proper input readings. Before connecting sensor to the controller, refer to the installation guide of the equipment manufacturer.

Typical VAV with 1 EC-Smart-Vue, 4 triac loads (1.6 VA each), 2 analog outputs (20 mA each), and actuator activated. 4. Device terminals are not capable of accepting two 14 AWG wires (when daisy-chaining devices). Use a wire nut with a pig tail to make such a connection. Any installation condition that is outside of the parameters of Table 6-1 should be avoided. Use an external fuse on the 24VAC side (secondary side) of the transformer, as shown in Figure 6-1, to protect all controllers against power line spikes. Maintain consistent polarity when connecting controllers and devices to the transformer. One terminal on the secondary side of the transformer must be connected to the buildings ground. All 24V COM terminals of all controllers and peripherals throughout the BACnet MS/TP network must be connected to the grounded transformer terminal as shown in Figure 6-1. This ensures that the 24V COM terminals of all devices connected to any BACnet MS/TP bus in the building are at the same potential. A mechanical ground is unacceptable: Do not use a pipe, conduit, or vav control wiring work for a ground. The power supply must have a dedicated ground wire that comes from the main electrical supply panel. Failure to maintain consistent polarity throughout the entire BACnet MS/TP network will result in a short circuit and/or damage to the controller! The COM terminals of the controller are internally wired to the 24V COM terminal of the power supply. Connecting a peripheral or another controller to the same transformer without maintaining polarity between these devices will cause a short circuit. 4

The EC-Smart-Vue is a Communicating room temperature sensor with backlit display and graphical menus. and has VAV balancing capabilities. Connect the EC-Smart-Vue to the controller with a standard Category 5e Ethernet patch cable fitted with RJ-45 connectors. If you make your own patch cable, use Category 5e cable crimped with RJ-45 connectors either as T568A or T568B.

Patch cables fitted with connectors supplied by Distech Controls are wired as T568B.

Do not crimp one connector as T568A and crimp the other connector as T568B on the same cable. Protect the controllers connector from being pulled on when a cable to the EC-Smart-Vue is connected. Create a strain-relief by looping the cable and attaching it to a solid object with a nylon tie so that a tug on the cable will not pull out the connector on the controller. 5

9. Output Wiring
The controllers have physical connections for either digital (triac) and/or universal outputs, depending on the type and model. The power source type for digital outputs is hardware configurable and must be configured by changing the jumper settings on the printed circuit board. The universal outputs are software configurable. Before connecting an output device (actuator, relay, etc.) to the controller, refer to the installation guide vav box with electric heat the equipment manufacturer.

Universal outputs can be configured to provide either a discrete signal of 0 or 12VDC or a linear signal ranging from 0 to 10VDC. The discrete signal can be used to generate a pulse wave modulation vav control wiring signal or a simple two-state signal. These outputs are protected by an auto-reset fuse. Wiring Discrete Outputs If a 12VDC relay is being controlled, connect it to a universal output according to the following figure.

For a wire length less than 75 (23m) long, either a shielded or unshielded 18AWG wire may be used. For a wire up to 200 (61m) long, a shielded 18AWG wire is recommended. The shield of the wire should be grounded on the controller side and the shield vav control wiring should be kept as short as possible.

Wiring Digital Outputs (DOx)

The digital outputs are all made of triacs and can be configured as either powered outputs or non-powered vav control wiring and output wiring must be done accordingly. Figure 9-5:

The non-powered output type does not have any voltage on the output terminals when the output is active. Power must be supplied externally. - The powered output type has 24VAC on the output terminals when the output is active. Power is therefore supplied internally by the controller. It should be noted that all controllers are shipped with all digital outputs configured as powered outputs. Maximum vav control wiring current for all digital outputs (whether powered or non-powered) is 0.5A continuous or 1A @ 15% duty cycle for a 10-minute period. DO1 vav control wiring DO2 share the same C1-2 common terminal and are controlled vav control wiring a single jumper and must therefore be set identically. Similarly, DO3 and DO4 (VAV, VVT and ECB-103 product lines only) share vava e gay same C3-4 common terminal and are controlled by a single jumper and must therefore be set identically. The jumpers are used to specify whether an internal or external power source is being used.

14. Setting the BAUD Rate (optional)

By default, the BAUD rate for the controller is set to automatically detect the current communication BAUD rate of the connected BACnet MS/TP network (AUTO). This is the preferred setting for a controller. However, at least one controller on the BACnet MS/TP network data bus must have its BAUD rate set. The preference is to set the building controllers BAUD rate (if present). Otherwise, set the Vav control wiring rate on one controller that will set the BAUD rate for all other controllers (to act as the master for setting the BAUD rate). When the Baud rate is set to AUTO, the controller cannot initiate any communication until it has detected the baud rate of the BACnet MS/TP network. If all controllers on the BACnet MS/TP network are set to AUTO, then all controllers will not communicate. Set the connected controllers BAUD rate as follows: 1. Connect an EC-Smart-Vue to the controller with a Cat 5e patch cable. Wait for the display to show the room temperature. 2. Press and hold the Menu button for 5 seconds to enter the password menu. 10000 is shown on the display. 3. Use the down button to set the number to 9995 (this is the default password). 4. Use the Menu button to select GEN CFG. 5. Press the down button once to enter the GEN CFG submenu. The MAC ADDRESS menu is shown. 6. Use the Menu button to select BAUD RATE. The current controllers BAUD rate is shown. 7. Use the up and down buttons to set the controllers Baud rate. AUTO detects and uses the Baud rate currently being used by the BACnet MS/TP network. 8. Press the Menu button once to apply the value. 9. Press vav control wiring hold the Menu button for 5 seconds to exit the configuration menu.

Controller is powered but does not turn on
Fuse has blown Power supply polarity Disconnect the power.Check the fuse integrity. Reconnect the power. Verify that consistent polarity is maintained between all controllers and the transformer. Ensure that the 24VCOM terminal of each controller is connected to the same terminal on the secondary side of the transformer. See Figure 61. 1. Check power supply voltage between 24VAC 15% and 24VCOM pins and ensure that it is within acceptable limits. 2. Check for tripped fuse or circuit breaker. Verify that the transformer used is powerful enough to supply all controllers. Double check that the wire connections are correct. Check the network termination(s). Configure the maximum number of master device on the MS/TP network in all devices to the controllers highest MAC address used on the MS/TP vav control wiring. Check that the total wire length does not exceed the specifications of the Network Guide. Check that the wire type agrees with the specification of the Network Guide. Idir lyrics a vava inouva 2 check that the wire connections are correct. Check the network termination(s). Incorrect or broken termination(s) will make the communication integrity dependent upon a controllers position on the network. The number of controllers on a channel should never exceed 50. Use a router or a repeater in accordance to the Network Guide. Configure the maximum number of master vav box with electric heat on the MS/TP network in all devices to the controllers highest MAC address used on the MS/TP trunk. Each controller on a BACnet MS/TP data bus must have a unique MAC Address. Use an EC-Smart-Vue to check the MAC Address of each controller. Each controller on a BACnet intranetwork (the entire BACnet BAS network) must have a unique Device ID. Use an EC-Smart-Vue to check the Device ID of each controller. Check that the wiring is correct according to this manual and according to the peripheral devices manufacturer. Using a voltmeter, check the voltage on the input terminal. Short circuit (0V) and open circuit (5V). Using the controller configuration wizard, check the configuration of the input. Refer to the controllers user guide for more information. An over-voltage or over-current at one input can affect the reading of other inputs. Respect the allowed voltage / current range limits of all inputs. Consult the appropriate datasheet for the input range limits of this controller. Disconnect the power and outputs terminals. Then wait a few seconds vav control wiring allow the auto-reset fuse to cool down. Check the power vav control wiring and the output wiring. Reconnect the power. Check that the wiring is correct according to this manual and according to the peripheral devices manufacturer. Using the controller configuration wizard, check the configuration of the output. Refer to the controllers user guide for more information. Check the polarity of the 24VAC vav control wiring supply connected to the actuator while connected to the controller. Reverse the 24VAC wire if necessary. Check the jumper settings for the external power supply as shown in Figure 9-3. Using the device configuration wizard, check the configuration of the input. Refer to the devices user guide for more information. 1. Recharge device with light (if solar-powered) or replace battery (if battery-powered), 2. Ensure sufficient light intensity (200lx for 4 hours/day). Reposition the device to be within the range of the Wireless Receiver. For information on typical transmission ranges, refer to the Open-to-Wireless Solution Guide. Using the device configuration plug-in or wizard, check the configuration of vava suresh 62 king cobra input. Refer to the Wireless Batteryless Sensors and Switches Solutions Guide for more information. 1. Make sure that the tubing is installed properly and that the tubing is not bent. 2. Verify that the high and low pressure sensors are not inversed. Recalibrate the controller. Refer to the controllers user guide for more information. The two mechanical stops must be positioned to stop the vav box with electric heat motion when it is completely closed and completely opened. The mechanical stops can be moved by increments of 5.

Hello, wondering if vav control wiring are any control contractors that could give me some "average" unit pricing for VAV control installation?

My scope for each VAV will be as follows- demoing old damper motor and controller then installing new damper motor and controller and installing diff pressure sensor, temperature sensor, MSTP/bus/communication, and connecting new thermostat.

I've discussed this with some guys locally and I've been given number from 750-1200. I have no experience with this so please help if you can. All input is much appreciated!

Yes this was posted in estimating section- no responses so thought I'd put it here.

power

air flow: electronic probe or pneumatic to VAV sensor?
is the sensor installed or do you need vav control wiring drill/install it?

figure 1/2 hr for the wall sensor
1 hr controller R&R
1 hr damper act R&R
1 vav control wiring sensors (airflow and duct temp)

perhaps 4-5 hrs per unit if existing wiring can be reused (including mob-demod, etc.)
plus some materials,s screws, etc.
I assume the control equipment is by others
painting/patching excluded
