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 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.

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 section “Wiring”.
5. (T7460B,C,D,E,F only) With the double-D hole of the
potentiometer in the "12 o'clock" orientation (see Fig. 4),
hold the setpoint dial such that the "21" (Celsius absolute
scale) or "0" (Celsius relative scale) is at the "3 o'clock"
position and then insert the dial into the hole.

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. 7 through Fig.
6.
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 Fig. 8.

T7460-LONJACK
The T7460-LONJACK is a small board allowing easy access
to LONWORKS or BACnet via the correspondingly wired wall
module (apply appropriate wiring guidelines for LONWORKS or
BACnet networks, as the case may be). The T7460-
LONJACK provides an additional 3.5 mm jack socket for a
3.5 mm jack plug.
