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.

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.
