I have a gas heating system with an old Honeywell thermostat. There are only 2 wires - R and W (W currently unhooked). I'm trying to see if I can replace the thermostat with a Google Nest Thermostat. And if so, which model? Do I need one with or without a C-wire?
I wanted to follow up and see if I could be of any help. I found an article with more details on compatibility. Please let me know if you are still having any trouble from here, as I would be happy to take a closer look and assist you further.
