Have no idea what I'm doing changing out thermostats and need help please.
OK, Got a new Honeywell Vision Pro 8000 Model # TH8320U1008 7day 3/h 2/c thermostat, going to swap out our old Trane thermostat and I'm not sure what wire goes where.
This is a Trane Heat pump unit with auxiliary heat. I thought it would have the same letters as the old one but it does not. Please look at the attached pictures and help me please.
The top picture is our current thermostat. Please let me know the correct placement for the old wires to the new thermostat.
I really appreciate the help. Thank You.
