Honeywell T7460A Wall Modules for Excel Controller Instruction Manual

Honeywell T7460A Wall Modules for Excel Controller

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, s ee 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, 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.

6. 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. 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.
