Review on Transformer Thermostat Competible Versions Honeywell by Greg Sullivan

Revainrating 4 out of 5

Difficult installation

The instructions are very vague. I have a 3rd gen Nest thermostat as my rc has been used before. I used Rh instead but got an error and the thermostat got stuck in the error message so I found out the two white wires aren't what they are. different polarities there is one with black lines one is power and the other goes to C so I used Rh and C which gave me an error which I was allowed to ignore but the error was still there so I did researched further and tried to connect power (wires with black lines) to Rc with the one already present, that way Nest would not see anything on RH and would use an internal jumper to complete the circuit. I think I could use a matching jumper but my solution was better in my opinion, look at the photo attached to my configuration, works great 👌🏼
