TR21, TR22, TR23, and TR24 20K Ohm Nonlinearized
Sensor:
All models are furnished with a 20K Ohm nonlinear NTC
temperature sensor that follows a specific temperature
resistance curve. See Fig. 1 on page 2.
NOTE: The TR21-A wall module model has two (2) 20K
Ohm nonlinear NTC temperature sensors in parallel,
which provide 10K NTC temperature sensing
necessary for averaging.

Communications
All wall modules (except the TR21 and TR21-A models) have
a LONMARK® bus communications port. If needed, the jack
plug must be removed in the field, and terminals 3 and 4 wired
according to the installation instructions.
The recommended wire size for the LONMARK® bus is Level
IV, 22 AWG (0.34 sq.mm) plenum or non-plenum rated,
non-shielded, twisted pair, solid conductor wire.
Fig. 2. Wall Module Features (TR23-F Shown).
BEFORE INSTALLATION
CAUTION
Erratic System Operation Hazard.
Failure to follow proper wiring practices can
introduce disruptive electrical interference (noise).
Keep wiring at least one foot away from large inductive
loads such as motors, line starters, lighting ballasts,
and large power distribution panels.
Shielded cable is required in installations where these
guidelines cannot be met.
Ground shield only to grounded controller case.
IMPORTANT
All wiring must comply with local electrical codes
and ordinances or as specified on installation wiring
diagrams.
— Wall module wiring can be sized from 16 to 22 AWG
(1.31 to 0.33 sq. mm) depending on the application.
— The maximum length of wire from a device to a wall
module is 1000 ft. (305 m).
— Twisted pair wire is recommended for wire runs longer than
100 ft. (30.5 m).
INSTALLATION
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. See “Cover Disassembly” on page 3.
The wall module can be mounted on a wall, on a standard
utility conduit box using No. 6 (3.5 mm) screws or on a 60 mm
wall outlet box (see Fig. 3). When mounting directly on a wall,
use the type of screws appropriate for the wall material.

Cover Disassembly
A snap-fit locking mechanism is used to attach the cover of
the wall module to its subbase. To disassemble the cover from
the subbase:
1. Insert a thin, flat blade screwdriver into each of the two
slots at the bottom of the module to release the two
locking tabs. See Fig. 2 on page 2.
2. Tilt the cover out and away from the subbase to release
the top two locking tabs.
3. To change the dial (e.g. from Fahrenheit to Celsius)
release the two tabs on the inside of the front cover and
remove the old dial.
Wiring
Attach the wires from the device sensor terminals to the
appropriate wall module terminals. See Table 1 on page 4.
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.
Wiring Wall Modules
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 (20 to 22 AWG only) are being
inserted into one terminal, twist the wires together
before inserting. See Fig. 5.
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 illustrated in Table 1 on page 4.
NOTE: Wire the Lon connection (terminals 3 and 4) using
Level IV 22 AWG (0.34 mm2) plenum or non-plenum
rated, unshielded, twisted pair, solid conductor wire.
Wiring Examples
Table 1 on page 4 illustrates DIP switch settings and terminal
connections for the wall modules. Refer to the TR21, TR22,
TR23, and TR24 Wall Modules – Specification Data, form
63-1321, for additional DIP Switch information.
IMPORTANT
SW 2 on DIP Switch S2 is used for factory calibration
of the temperature setpoint potentiometer.
Depending on calibration, this switch may be set in
either the On or Off position.
DO NOT change the position of this switch.
NOTES:
1. The TR21 and TR22 models do not use DIP
Switch S1 and S3.
2. DIP Switch S1 is used only on the humidity
models, TR21-H and TR23-H.
3. Models TR21 and TR21-A use terminals 1 and 2
only. Model TR21-J uses terminals 1, 2, 3, and 4
only.
Fig. 5. Attaching Two Wires (20 to 22 AWG) to Wall Module
Terminals.
Attaching the Cover
When all wiring is complete, attach the cover of the Wall
Module as follows:
1. Optional: For models with a temperature dial, insert the
two setpoint screws into the inside of the cover to set
the desired temperature range limit. See Fig. 4.
2. Press the cover straight down onto the subbase until it
snaps into place.
3. For models with a temperature dial, 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.

TR22 and TR23 Setpoint Adjustment
For the TR22 and TR23 Wall Modules with a setpoint
adjustment, the controller must be programmed for the values
in Table 2 and Table 3.
TR23-KL and TR23-H-KL
The TR23-KL and TR23-H-KL ship in packs of 20 and are
supplied without setpoint adjustment knobs. Knobs can be
ordered separately. See Table 4 for Knob model numbers.
Humidity Settings (DIP switch S1)
The humidity sensing control mode is set with this 2-position
DIP switch. Refer to Fig. 4 on page 3 for location of DIP switch
S1.
NOTE: These switch settings apply only to the TR21-H and
TR23-H models.
To change the setting, first disconnect the power, then set
SW1 and SW2 according to Table 5.

Operation
When Used With Excel 10 Controllers:
The Excel 10 controllers (W7750, W7751, W7752, and
W7753) provide timed occupied and unoccupied temperature
setpoints for the Wall Module, see Fig. 6. The override
pushbutton is used to change the controller into the modes
shown in Table 6 and illustrated in Fig. 7 on page 6. The
override (bypass) LED displays the override status of the
controller.

Fig. 7. Override pushbutton operation.
When Used With Excel 600/500/100/80/50
Controllers:
The application engineer/programmer can program the
override (bypass) and LED to operate in any manner desired.
The override (bypass) input is a dry contact, normally open,
momentary digital input when the wall module does not have a
fan switch. When a fan speed switch (basically a series of
resistances based on fan switch position) is present, the
override button is an analog input. See Table 4 for
resistances.
When Used With T7350 Thermostat:
TR21, TR21-A, TR21-H, TR22, TR23, and TR24 are the
models compatible with the T7350 thermostat. When using
with the T7350 thermostat be sure to use the relative +/- offset
knob only. The Celsius and Fahrenheit knobs will not work
properly with the T7350 Thermostat.
TR22-F5, TR23-F3, and TR23-F5 Wall
Module Fan Switch
With the switch in the far left position (Auto), the fan
automatically runs at the speed determined by the controller
temperature control algorithm.
With the switch in the 0 position, the fan is off. Position 1 is fan
speed 1, etc.
The wall module fan speed switch overrides the temperature
control algorithm.
When Used With Excel 10 Controllers:
The Excel 10 Controllers (W7750, W7751, W7752, and
W7753) can be programmed so that the fan speed switch and
override button function the way that the application engineer/
programmer wants. See Table 7 for controller-programming
resistances. Switch 1 on Dip Switch S2 adds 10k Ohms
resistance when OPEN (for Excel 600-80 controllers) and
removes it when CLOSED (for Excel 10 controllers).
When Used With Excel 600/500/100/80/50
Controllers:
Excel 600/500/100/80 Controllers can be programmed so that
the fan speed switch and override button function the way that
the application engineer/programmer wants. See Table 8 for
controller-programming resistances. Switch 1 on Dip Switch
S2 adds 10k Ohms resistance when OPEN (for Excel 600-80
controllers) and removes it when CLOSED (for Excel 10
controllers).
