Old trane vav boxes

So we are in the process of changing out all the controls in the Govt. buildings of a particular town. Old trane vav boxes tisha vav buiding we get to, happens to be the Tax building, has these old Trane VAV boxes that have the damper actuator inside in the box.it basically turns a threaded rod to move a round damper over the inlet hole and it backs away from the hole to allow air into the box. I cracked open the VAV box to see how it worked and it appears to have end switches at both ends that stop the shaft from turning at the appropriate place. There are 3 wires that leave the control board on the outside of the VAV box that go into the box to the accuator. The are labeled hot/open/close and I have verified its just 24v AC power open/power close. The end switches must be inline with its respected wire, either breaking the open wire or the close wire.

Heres where the problem comes in.all the materials for the entire job have been bought and whoever looked at this building missed these VAV boxes. We planned on using Siemens ATEC's and we may still do that. The boxes are only HW reheat. The ATEC has 2 spare DO's we could use to stroke damper. We would have to do everything with programming. Back in the day there was only one TEC(long board) that would hold programming but now when I look at applecation 6633 on WCIS the last sub point is PPCL state (Empty/Loaded).so this leads me to believe ATEC can now hold programming. Has anybody actaully old trane vav boxes PPCL into ATEC's? We could load all the programming into our panels but if the network goes down none of the VAV's would work right. Hopefully there are some Siemens guy out there that can provide some input.

SAFETY WARNING
Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and airconditioning equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment
by an unqualified person could result in death or serious injury. When working on the equipment, observe all precautions in old trane vav boxes literature and
on the tags, stickers, and labels that are attached to the equipment.

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

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 old trane vav boxes 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!

Failure to follow recommendations could result in death

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.

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 discharge 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 enviro-tec vav box k factor 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 or by using old trane vav boxes 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 electric heat fanpowered units used in old trane vav boxes with
100% downward discharge.
Note: In order to maintain 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.

Trane offers a factory-mounted actuator with a 90-second
drive time.The enviro-tec vav box k factor 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.

for the auxiliary sensor to determine the control action
(heat, cool) it must be located in the supply inlet of the
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 controls to the minimum flow set
point. If an auxiliary sensor is not installed the UCM will
retain the last control action in effect.
