Special functions
Auto Changeover
(Setup Function 0300): When set to Auto, the thermostat automatically selects
heating or cooling depending on the indoor temperature. Heat and cool settings must be at least 2
degrees apart.
Adaptive Intelligent Recovery
(Setup Function 0530): Allows the thermostat to “learn” how long
the furnace and air conditioner take to reach programmed temperature settings, so the temperature is
reached at the scheduled time.
Compressor Protection
(Setup Function 0580): Forces the compressor to wait a few minutes before
restarting, to prevent damage. During this time, the message “Wait” is on the display.
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.
