Hi...I have a Honeywell thermostat that controls a dual fuel unit.
Wiring g diagram attached. I need assistance wiring a new nest learning
thermostat 3rd gen with a blue bubble level.Thanks!!
Thanks for the reply. That does not make much sense, since I installed
the older Honeywell dual fuel thermostat myself. If I have to pay a pro
installer several hundred dollars to install it, it negates the reason I
bought the thermostat - to save on...
