c. Tighten the two mounting screws to the room unit
base plate.
6. Do the following:
• Inspect the RJ-11 connector for damage.
• If the RJ-11 was damaged: Cut the cable, leaving
about three inches (75 mm) on the room unit side
of the drywall, and attach an RJ-11 connector with
an RJ-11 crimping tool. On the RJ-11 connectors,
ensure that pin Number 1 connects to the same
wire at each end of the cable. See Figure 4.
CAUTION:
For retrofits: Before cutting the cable,
make sure it is disconnected from the
Room Unit port on the controller cable
end.
Figure 4. Terminating the RJ-11 Connector.
7. Plug the terminated cable into the RJ-11 connector on
the back of the room unit's printed circuit board (PCB).
8. Feed the extra cable back through the hole.
9. Snap the room unit cover to the room unit base plate
by first hooking the room unit front to the top latches,
and then rotating the cover downward until it latches.
10. Loosen the safety set screw at the bottom of the base
one or two revolutions to lock the cover to the base.
Be careful not to loosen too far as the screw can be
completely removed from the base.
NOTE: If installing QAA or QFA models, drywall
mounting is complete. If installing QPA
models, proceed to Steps 11 through 13.
11. Connect the RJ-11 cable from the room unit to the RJ-
11 connection on the CO
2
Power Module (AQM2200).
Make sure the cable is connected to the correct RJ-11
port.
12. Terminate the CO
2
Power Module power wires to the
TEC power connector or the 24 Vac transformer or
other 24 Vac transformer (See AQM2200 Power
Module Installation Instructions 129-111 for detailed
information). The CO
2
Power Module may be powered
off the same power source as the TEC.
13. Connect the RJ-11 Cable from the CO
2
Power Module
to the RJ-11 Temperature Room Unit port on the TEC.
The installation is now complete.
Electrical Box and Rough-in Mounting,
Typical
1. If a locator is attached to the rough-in device, remove
the locator by removing the two screws and lightly
rocking the locator to pull it free.
2. Untie the twist tie and pull about three inches (75 mm)
of the room unit cable through the hole in the base
plate.
3. Mount the room unit base plate on the wall, noting the
UP arrow:
NOTE: If required, position the Back Plate behind
the Room Unit Base, aligning the top and
bottom mounting holes, prior to mounting
to the wall.
a. Install the two room unit mounting screws
provided, but do not tighten.
b. Level the room unit base plate for appearance
only.
c. Tighten the two mounting screws to the room unit
base plate.
CAUTION:
Over-tightening may cause the room unit
base plate to crack or bend.
4. Continue with Drywall Mounting (No Rough-in),
Typical, Steps 7 through 13.
The installation is now complete.
