True air replacement thermostat

[imnprsd]

Thanks for reviving this thread. I read all about Duner's upgrade and learned something important about those 2 grey wires connected to the Coleman-Mach Thermostat an the condenser freezing over when you call the heat pump to run in sub-40F weather.

Here's a thermostat wire diagram with labels that match previous discussions.

Note: The Coleman-Mach has 12 total wires. 9-wires go to the Coleman-Mach (2-Ton) Basement AC & Heat Pump and 3-wires go to the Suburban Heater.
