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.
Fig. 2. Wall Module subbase dimensions in inches (mm)
(TR23 shown).
Fig. 3. Mounting the wall module on the wall and
temperature limit set screw locations (TR23 shown).
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
(1.31-0.82 sq. mm) with a wire nut. Include a pigtail
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
into one terminal, be sure to twist them
together. Deviation from this rule can result
in improper electrical contact. See Fig. 4.
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.

DIP Switch Labels
This device is packed with tear-off DIP switch labels you can attach to the receiver and indicate which DIP switches are on and
off.

switches matching S2 and S3 DIP switches on receiver.
TESTING FOR SIGNAL
STRENGTH
When the receiver is powered and batteries are placed in the
wall module, communication will begin automatically within 2
seconds. The receiver RF signal light will flash every 30
seconds to confirm each transmission. You can force
immediate communication by pressing the signal strength
button on the side of the wall module with a 1-1.6 mm
diameter probe with flat or rounded face (a common paperclip
will do) (see Fig. 9). This may be required to initiate
communication when replacing a wall module.
The signal strength LED next to the signal strength button will
light up on the side to show the relative signal strength. The
signal strength LED will initially light amber when the signal
strength button is pressed to verify that you are pressing the
signal strength button. When you release the signal strength
button, the light will behave as shown in Table 1.

Fig. 9. Wall module features (TR23 shown).
If no signal is received, test the wall module in a different
location until a suitable signal strength is received by the
receiver. Pressing the signal strength button on the wall
module will cause a five-second flash on the RF signal LED
on the receiver, and pressing the override button will cause a
single flash on the receiver.
If communication is lost between the wall module and
receiver, the receiver will try three times to reestablish
communication. After 3 tries (90 seconds), the receiver will go
into a sleep mode, and will retry to communicate every 10
minutes. Output from the receiver will be an open circuit for
temperature and setpoint output (simulating cut wires on a
wired sensor). Communication will re-establish automatically
once signal is within range.
BINDING THE WALL MODULE
AND RECEIVER TO EACH
OTHER
The TR21-WK and TR23-WK wireless kits include a wall
module and receiver that have already been bound in the
factory to automatically communicate with each other. They
can be identified as matching by the identical bind numbers
printed on the labels. The S2 and S3 DIP switches on the
receiver (used to bind the two devices) and the 12 DIP
switches on the wall module will all be in the OFF position. As
soon as power is applied to the receiver and the batteries are
installed in the wall module, the two devices start to talk to
each other. If the two devices don’t communicate immediately,
remove and re-install one battery, leaving it out for 10 seconds
OR you can initiate communication by pressing the signal
strength button on the sensor (using paperclip).
Each wireless kit has a unique binding, so even though
multiple wireless kits have S2 and S3 switches all in the OFF
position, each device will only communicate to the device to
which it was paired and shipped as a kit.
There may be times when you want to bind a receiver to a wall
module using the DIP switches. This is done simply by
matching any S2/S3 DIP switch settings on the receiver with
the DIP switch settings on the wall module. Wall modules in
close proximity must have different DIP switch settings
(except when modules are using the all-OFF default binding).
DIP switches S2/S3 are provided for two reasons:
• If the wall module needs to be replaced, a TR21-WS or
TR23-WS wall module can be purchased. To bind any wall
module and receiver, simply set the DIP switches S2/S3 on
both the receiver and the wall module to any matching DIP
configuration. To prepare for this ahead of time, the
receiver and wall module in the WK kit can be set with a
matching dip switch configuration when mounted. The tear
off tab on the receiver allows the installer to write down the
on/off DIP configuration. Then the new wall module’s DIP
switches can be set by matching the old wall module’s DIP
switches, without having to set or check the DIP switches
on the receiver.
• If wall modules and receivers get mixed up in the field
(even though they are marked with matching numbers from
the factory), DIP switches can be used to bind any wall
module to any receiver simply by matching the S2/S3 DIP
switches. If setting DIP switches, be sure that each
wireless sensor/receiver pair in a given building has a
unique DIP switch setting to prevent cross-talk.
Fig. 8 shows matching DIP switch settings binding the wall
module and receiver.
Controller Matching
The TR21 and TR23 wireless wall modules can be used with
many different controllers. The S1 switch on the receiver can
be set for a number of different controller requirements. See
Table 2 for DIP switch settings, and see Table 3 for a
description of the controller.

Low Battery Signal
When there are approximately 2 months of battery life
remaining, the LED on the front of the wall module (next to the
Override button) will flash red every 15 seconds. In addition,
the LOW BAT digital output from the receiver will close. This
LOW BAT output signal can be sent to an unused DI on the
controller to let the user know that there is a low battery
condition. Replace the batteries whenever the LOW BAT
contact closes, or flashing red light is seen next to the
Override LED on the face of the wall module. Normal
operation will automatically resume.
NOTE: If the batteries go dead, the LOW BAT digital output
(open/close) signal will open again. The LOW BAT
digital output will close only when batteries are run-
ning low, not when they are completely dead, or are
not installed. This ensures that a lack of signal is not
confused with dead or missing batteries. Whenever
there is no signal, or batteries have gone completely
dead, the receiver LOWBAT output will send an open
circuit reading to the controller for temperature (and
set point, if applicable).
Override Button
To save battery life, the override button LED will only light
when the button is pressed. It will not remain lit, as on
standard wired TR23 and TR24 models. Override will still be
activated when the button is pressed. If using with the XL10,
pressing and briefly holding the override button will cause it to
behave like other standard wired TR23s. The LED will
remain lit for 9 seconds max. to confirm it has been pressed
from 1-4 seconds.
REPLACING A WALL MODULE
When replacing a wall module, set the DIP switches the same
as the wall module being replaced. If the previous wall module
DIP switches are all set to OFF, it will be necessary to reset
the S2 and S3 receiver dip switches to any configuration not
being used by other receivers in the area, and then set the
wall module DIP switches to the same setting. At least one of
the 12 DIP switches must be set to the ON (up) position.
General Rules for Installing Wireless
Wall Modules
Communication between the wall module and receiver can be
influenced by a number of factors. Type and thickness of
building materials and the way in which they are oriented in
relation to the wall module and receiver will affect
communication.
Do not place either the wall module or receiver inside metal
cabinets or enclosures.Try to orient the wall module and
receiver so that if they are separated by a wall(s), the direction
of signal travel is as perpendicular to the wall(s) as possible.
This reduces the effective wall thickness.
When mounting the receiver on a metal duct, stronger
communication is possible if the wall module is on the same
side of the duct so the signal doesn’t need to travel through
the metal duct.
Reduce as much as possible the amount of metal (ducts, file
cabinets, etc.) between the sensor and the wall module.
Standard drywall (gypsum board) does not greatly affect
signal strength.
For the most robust wireless link, install the wall module in
locations with the strong signal (Green light as described in
Table 1).
