THP9045 Wiring Module

APPLICATION

The THP9045 Wiring Module is designed to be used with

applicable thermostats in which a 24V common is

required and there are not enough wires. The K terminal

on the thermostat can be used to operate both the fan

and compressor on a single wire, and the module is

designed to receive the signal from the K terminal, split

that signal and re-route it to operate the compressor,

and/or fan for normal operation.

Use with the following thermostats:

— THX9321R

— THX9321R5000

— THX9321R1008

— TH8320UP1003

— T5060F7088

FEATURES

• Can be used when a common wire is required.

• Mounts easily on or near HVAC equipment.

INSTALLATION

1. The THP9045 Wiring Module can be equipment- or

wall-mounted in any orientation or as dictated by

the surroundings.

2. Precise leveling of the THP9045 module is not

required.

3. Identify the four wires in the wall and connect to the

R, C, W, and K terminals on the thermostat.

4. Wire the K terminal on the thermostat to the K ter-

minal on the THP9045 module.

5. Wire the R and C terminals on the thermostat to

the R (power) and C (common) terminals on the

THP9045 module and equipment.

6. Wire the W terminal from the thermostat to the W

(heat relay) terminal on the HVAC equipment.

7. Wire the Y and G terminals on the Module to the Y

(Compressor Relay) and G (Fan Relay) terminals

on the HVAC equipment.
