WALL MODULES

HONEYWELL EXCEL 5000 OPEN SYSTEM

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

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.

See Fig. 3 for mounting dimensions.

NOTE: Graphics depict E/F model. Dimensions are the

same for all six models.

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,

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.

6. (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 through

Fig. 8.

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. 8 and wall module wiring

with Fig. 6 and Fig. 7.
