I have a Climate Master Tranquility 27 Model # TTV038AGC01ARKS Serial # 13316228 I am in need of a new thermostat and would like to know which would be the best one that is compatible . My current thermostat is the old 7 day programmable type and would like one with newer features and that would allow the system to run in stage 1 for more than 3-5 minutes. I don't know if the Climate Master IGate is compatible but would love the trouble shooting component of that one.

I used a Ecobee with mine. You can set the temp to stage timing and delays.
