WALL MODULES
INSTALLATION INSTRUCTIONS
BEFORE INSTALLATION
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 (1.5
to 0.34 mm2), 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).
COVER DISASSEMBLY
The cover of the wall module is fixed in place using a tab
located on the underside of the unit; to disassemble the
cover and the subbase, see Fig. 1.
Fig. 1. Cover disassembly.

INSTALLATION
The T7460B,C,D,E,F packages include two setpoint dials.
By default, the “Celsius Relative” type is mounted. This can
be easily replaced with the “Celsius Absolute” type by
pulling the one dial off and inserting the other one.
Mount the T7460A,B,C,D,E,F Wall Modules on an inside
wall approximately 54 in. (1.3 m) from the floor (or in the
specified location) to allow exposure to the average zone
temperature.
NOTE: Maintain a mounting clearance of approx. 4 in.
(10 cm) to the left-hand side of the module in
order to allow a free airflow for the temperature
sensor and accessibility of the setpoint dial.
Do not mount the wall modules 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.
The T7460D,E,F should not be connected to
controllers that do not support fan operation
(e.g. W7751, W7762, W7763).
Keep wiring at least one ft (305 mm) away from
large inductive loads such as motors, line starters,
lighting ballasts, and large power distribution
panels.
Run wall module wiring separately from 50 Vac or
greater power wiring.
The wall modules can be mounted on a 60-mm wall outlet
box using No. 6 (3.5-mm) screws or on a wall (see Fig. 2
and 5). When mounting directly on a wall, use the type of
screws appropriate for the wall material.

Mounting Procedure
1. Disassemble the cover as is shown in Fig. 1.
2. (T7460B,C,D,E,F only)
Remove the setpoint dial by pulling it off.
3. a) Mount the wall module onto the wall outlet box,
or
b) bore wall holes as is specified in Fig. 2 and
mount the wall module with appropriate screws.
4. Connect the wires to the terminal block according
to the specifications in the “Wiring” section.
5. (T7460B,C,D,E,F only)
Insert the setpoint dial and turn it clockwise as far
as possible.
1. (T7460B,C,D,E,F only)
Make sure that the dial's position is such that the
30 (Celsius absolute scale) or the +5 (Celsius
relative scale) point to the right-hand side of the
wall module (see Fig. 4).
Fig. 4. Mounting position of setpoint dial.
7. (T7460B,C,D,E,F only)
If the dial does not have the correct position, pull
the dial off again and reinsert it with the correct
orientation.
8. Remount the cover as depicted in Fig. 5 and make
sure that the tab on the underside engages.

Wiring
Attach the wires from the device sensor terminals to the
appropriate wall module terminals and set the jumpers
according to the connected controller. See Fig. 6, 7 and 8.
NOTE: Not all of the T7460 wall modules are compatible
with W7751A,C,E,G(VAV1) and W7752D1(FCU1)
Controllers.
IMPORTANT
Screw type terminal blocks are designed to
accept no more than one 16 AWG (1.5 mm2)
conductor.
Wire the terminal blocks as follows:
1. Strip 3/16 in. (5 mm) of insulation from the
conductor.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
3. Verify jumper setting with Fig. 6 and wall module
wiring with Fig. 7 and 8.
Jumper settings
According to the type of controller connected, the following
jumpers have to be set on the PCB of the T7460C,D,E,F.
NOTE: The “W77xx” at the first jumper position stands for
the Excel 10 and Excel 12 controllers:
