Honeywell T7460A Installation Instructions Manual

HONEYWELL EXCEL 5000 OPEN SYSTEM
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 ), depending on the application. The maximum
2
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
controllers 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.
