and remove the enclosure cover. Using the rear
panel of the enclosure as a template (Figures 1
and 2), mark the location for the four screw
holes where you will install the enclosure.
2. Do one of the following:
•If using the self-tapping screws: Using
the drill and the hex nut bit, start the
screws. (Screws do not require starter
holes.)
•If not using the self-tapping screws: Drill
four

Figure 1. Room Pressurization Controller – Pneumatic Output without Autozero Modules.
3. Mount the enclosure on the screws and tighten
them down with either the drill or hex nut driver.
4. Remove the appropriate knockouts.
5. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
6. Connect the Local Area Network (LAN) trunk
(Figure 4). Run the wiring through knockout.
CAUTION:
Do not connect an earth ground to
the Shield (S) terminal.
7. Connect the point wiring for the appropriate
application. See Figure 7. See Table 1 for
application descriptions. Run the wiring through
knockout.
CAUTION:
The Controller’s Digital Outputs (DOs)
control 24 Vac loads only. The
maximum rating is 12 VA for each DO.
For higher VA requirements, 110 or
220 Vac requirements, separate
transformers used to power the load,
or DC power requirements, use an
interposing 220 V 4-relay module
(TEC Relay Module P/N 540-147).
NOTE: Each DO provides a Normally Open
(NO) and a Common (C) terminal. Terminate
both connections of a 24 Vac load directly to the
controller board.
NOTE: The 24 Vac “H” terminal is switched
through a TRIAC to the NO terminations when
the associated DO is energized.
8. If using a pressure mode switch, then follow the
Room Pressurization Controller (RPC) Pressue
Mode Switch nstallation Instructions (540-719)
included with the switch.
9. After the pressure mode switch is installed, wire
the switch to DO8 and AI3 as described in the
instructions.
10. Plug the Room Temperature Sensor cable into
the RTS port on the controller board. See
Figure 1. Run the cable through knockout.
11. Connect the power trunk as shown in Figure 5.
DO NOT apply power to the controller. Run the
wiring through knockout.
12. Replace the enclosure cover and tighten the
cover screws.

The following task can be performed by the fitter:
13. Connect the tubing from the air velocity sensor
pickups to the HI and LO ports outside of the
enclosure. The supply pickup goes to the supply
AVS ports, and the exhaust pickup goes to the
exhaust AVS ports on the side of the enclosure.
Make sure that the “HI” and the “LO” pressure
sides of the sensors are connected to the “HI”
and “LO” sensor ports on the controller
(Figure 1) or Autozero Modules (Figure 2). Refer
to Table 2 for air velocity sensor connections.
The installation is complete.
Replacement Instructions
CAUTION:
Replacement of a TEC requires you
to record, re-enter, or update the
initial point values of the controller
you are replacing. These are the
points marked with an asterisk (*)
on the Controller Interface Software
(CIS) display.
NOTE: CIS Rev. 2.0 or later is required for controller
replacement.
The following tasks can be performed by the system
specialist:
1. Place the ESD wrist strap on your wrist and
attach it to a good earth ground.
2. Before disconnecting the old controller, do one
of the following:
NOTE: If the new controller has a newer
firmware revision than the old controller, then
skip to the third bullet.
•If the old controller communicates with the
field panel, then update the controller initial
values at the field panel.
•If the old controller does not communicate
with the field panel, but communicates with
the CIS, or if the controller is stand-alone,
then record the initial values (those marked
with an asterisk (*) on the CIS display).
Record the values.
•If the old controller is not communicating at
all, or if the controller you are installing has a
newer firmware revision than the old
controller, then while at the field panel,
follow these steps:
a. Obtain a field panel Point Definition
Report for the LCTLR point. Record the
values.
b. View the initial value block. (This
information is valid only since the last
update was made). Record the values.
c. Delete the LCTLR point from the field
panel.
3. Replace the old controller as follows:
The following tasks can be performed by the
electrician:
a. Remove power from the controller.
b. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then disconnect the wires
from the power trunk terminal block. If the
old controller has the RTS plug on the
opposite end of the board from the power
trunk terminal block, then remove the
power trunk terminal block.
c. Remove, in the following order, the
controller’s:
•LAN trunk terminal block
•DO8, AI3, and DI2 only
•room temperature sensor
d. Loosen, but do not remove, the mounting
screws.
e. Lift and remove the old enclosure.
f. Mount the new enclosure on the mounting
screws and tighten them down with either
the drill or hex nut driver.
g. Remove the appropriate knockouts.
h. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then remove all terminal
blocks (except the power trunk) from the
new controller. If the old controller has the
RTS plug on the opposite end of the board
from the power trunk terminal block, then
remove all terminal blocks.

i. Plug, in the following order, the controller’s:
•pre-wired LAN trunk
•DO8, AI3, and DI2
j. If the old controller has the RTS plug
between the LAN trunk and point
terminations, then rewire power to the
power trunk terminal block. If the old
controller has the RTS plug on the opposite
end of the board from the power trunk
terminal block, then plug the power trunk
terminal block from the old controller into
the new controller.
k. Connect the room temperature sensor. Run
the wiring through knockout.
l. Power up the controller.
The following tasks can be performed by the
fitter:
m. Label and remove the polyethylene tubing
from the old enclosure.
n. After the new enclosure is in place,
reconnect the polyethylene tubing.
The following tasks can be performed by the system
specialist:
4. Set the address and application at the new
controller.
5. Based on what you did in Step 2, do one of the
following:
•If you updated the initial values from the old
controller at the field panel, then when you
set the address and application for the new
controller, the field panel will automatically
send the initial values down to the new
controller. Once this takes place,
replacement is complete.
•If you manually recorded the initial values in
the table, then enter them into the new
controller. If a field panel is present, then
update the controller’s initial values.
Replacement is complete.
•If there was no communication at the old
controller, or the new controller has a newer
firmware revision than the old controller,
then enter the initial values into the new
controller. At the field panel, add the LCTLR
point and update the controller’s initial
values. The replacement is complete.

loads only. The maximum rating is
12 VA for each DO. For higher VA
requirements, 110 or 220 Vac
requirements, separate
transformers used to power the

NOTE: Refer to the unit wiring diagrams or consult
with the local representative if terminations are
missing or are different.
NOTE:
When wiring any actuator that uses a 0
to 10V control signal and ties AC neutral
to DC common, an additional wire must
connect the actuator AC neutral to the
DC common of the PTEC/TEC AO
being used to control the actuator.
