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.
In normal operation, the sensor transmits to the receiver every
30 seconds. If the receiver fails to receive a signal after 15
attempts (7.5 minutes), the receiver will try to re-establish
communication every minute for 8 consecutive minutes.
During this time (maximum 15.5 minutes) the receiver will
continue to output the last valid temperature value it received
from the sensor. If there is no valid signal received after 15.5
minutes, the receiver will simulate an open circuit (like a cut
wire on a wired sensor) and go into a sleep mode. Thereafter,
every ten minutes, the receiver will try to re-establish signal.
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
M29048
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.
