If the cable is non-terminated or if the RJ-11
was damaged: Cut the cable, leaving about
three inches (75 mm) on the sensor 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. Use the wire nuts
supplied to connect the fan switch wires or
cables.
CAUTION:
For retrofits: Before cutting the cable,
make sure it is disconnected from the
Room Temperature Sensor (RTS) port on
the controller cable end.
Figure 4. Terminating the RJ-11 Connector.
8. Plug the terminated cable into the RJ-11
connector on the back of the sensor's printed
circuit board (PCB).
9. Connect the fan switch to the appropriate
controller leads using the wire nuts supplied.
Feed the extra cables and/or back through the
hole in the rubber insulator.
10. Snap the sensor front to the sensor base plate
by first hooking the sensor front to the bottom
latches, and then pushing the top of the sensor
front into place until it latches.
11. Tighten the sensor front retaining screw. See
Figure 3.
12. Connect the sensor to the Room Temperature
Sensor (RTS) port on the controller. Connect the
fan switch cables (wires) to the appropriate
controller terminal.
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 sensor cable(s) into the space.
3. If you have a single-sensor electrical box, install
the electrical box adapter plate. See Figure 5.
4. If you have a double-sensor electrical box, install
the required mounting plate(s).
5. If you use a universal adapter kit for a retrofit
job, install the multi-slotted plate in place of the
electrical box adapter plate. See Figure 5.
6. Pull the cable(s) through the required mounting
hardware in the order shown.
7. Install the two sensor mounting screws provided
but do not tighten.
8. Mount the sensor base plate on the wall, noting
the "UP" arrow on the stabilizer plate:
a. Level the sensor base plate for appearance
only.
b. Tighten the two mounting screws to the
sensor base plate.
CAUTION:
Over-tightening may cause the sensor
base plate to crack or bend.
7. Continue
with
Drywall Mounting (No Rough-in),
Typical,
Steps 7 through 13.
The installation is now complete.
