I'm submitting pictures of my old White/Rodgers Thermostat. I'm going to replace it with the Nest. Nest only model. Not the E or Learning model.
The configuration test gives it a go. I'm not sure. Want confirmation from a knowledgeable person, not a computer question, and answer test.
Thanks in advance. If you suggest any readings, please let me know what to check. There are only the two wires connected to the thermostat. One is White and the other is Red. As you see, there is electrical tape connecting the wires. Not wire nuts. Also, the wires are solid. There are two wires snipped and not used. I'm not too sure of the colors, as this is a very old thermostat. Seems that the cut, unused ones are Blue, and/or Green or Black. My heating system is Gas heated water to radiators. No Air Conditioning.
Thank you for taking the time to let us know about your inquiry. I'd be happy to take a look into this for you.
The Nest Thermostat (2020) version often requires a C wire to work. You might need to hook one bare wire available into the C terminal from your system control panel to your thermostat to consistently deliver power. You can also check your system’s compatibility before purchasing a Nest thermostat with our online Compatibility Checker.
Feel free to let us know if you have more questions.
