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 mm

2

), 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 sub-base, see Fig. 1.

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 con-
trollers that do not support fan operation (i.e., the 
W7751, W7762, W7763, W7704, and XFC2xxxx / 
XFC3xxxx). 
When used with CPO-FB22344R-xxx controllers, 
either setpoint override or fan-speed adjustment is 
supported. 
Keep wiring at least 1 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 Fig. 
5). When mounting directly on a wall, use the type of screws 
appropriate for the wall material.
