Mounting the Wall Module
Mount the wall module on an inside wall approximately 54 in.
(1372 mm) from the floor (or in the specified location) to allow
exposure to the average zone temperature. Do not mount the
wall module on an outside wall, on a wall containing water
pipes, or near air ducts. Avoid locations that are exposed to
discharge air from registers or radiation from lights,
appliances, or the sun. When mounting to drywall, use the
horizontal mounting screw locations, as shown in Fig. 3.

There is a locking screw option to prevent tampering and
access to batteries. The screw is provided with the wall
module, and screws into the slot shown in Fig. 9 after the
device is snapped onto the subbase.

If desired, insert the two red end stoppers into temperature
scale to set the desired temperature range limit. See Fig. 3.
For TR23 models, insert the desired dial through the opening
in the cover. Align the keyed shaft on the knob with the keyed
slot into the fitting on the subbase, then press down until it
snaps into place.
WIRING
Attach the wires from the device terminals to the appropriate
receiver terminals.
CAUTION
Improper Electrical Contact Hazard.
Screw type terminal blocks are designed to accept
no more than one 16 AWG (1.31 sq. mm)
conductor.
Connect multiple wires that are 16-18 AWG
4-11/16
(1.31-0.82 sq. mm) with a wire nut. Include a pigtail
(119)
with this wire group and attach the pigtail to the
individual terminal block.
Wire the terminal block as follows:
1. For single wires, strip 3/16 in. (5 mm); for multiple wires
going into one terminal, strip 1/2 in. (13 mm) insulation
from the conductor.
2. If two or more wires (18 to 22 AWG only) are being
inserted into one terminal, twist the wires together
before inserting.

NOTE: When two or more wires are being inserted
3. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
4. Review and verify the terminal connection wiring and
DIP switch settings.
