I am trying to replace my Honeywell Prestige IAQ thermostats. I noticed that my downstairs thermostat has a dehumidification option (upstairs shows no such option). I checked the wiring at the Honeywell equipment module and saw nothing connected to the U section nor did I see any H, or DEHUM wires.
The thermostat shows that it does dehumidification using the high-speed fan of the AC. Does that mean my furnace which is a Trane XT80 doesn't have a whole house dehumidifier and the nest e can handle this. I think this is similar to the "Cool to Dry" feature of the nest.
