EQUIPMENT
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:
