Installing Honeywell Lyric T5 Smart Thermostat
Posted: Sun Dec 29, 2019 12:07 pm
I hope I'm in the right forum. I'm trying to install a smart thermostat. Last month I had to have a repair to the old Coleman furnace and the technician said I have the necessary "C" wire. However, my old thermostat which is digital doesn't have a "C" terminal. I know "C" wires are often blue and the only blue wire is attached to the "Rc" terminal. Do you all know if that would be the "C" wire? I cannot find any information online for this.
