Help with installing Trane TZEMT400AB32MAA Thermostat
Happy Holidays everyone!
I'm trying to install a new thermostat and am totally confused on the wiring from old to new. Can anyone offer any advise? Do I need to run a wire from RC to RH and stick the red wire coming out of the wall into either?
Not sure what to do with the Red wire.
Thanks in advance!!
