Optional THP9045 Wiring Module
The THP9045 Wiring Module is designed to be used with applicable thermostats in 1 Heat/1 Cool
retrofit applications where only 4 wires are available. 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 reroute it to operate the compressor,
and/or fan for normal operation. See the THP9045 manual for further details.
