2 wires only! Nest won’t work

My boiler zones for radiant heat just keep clicking on and off, on and off when the Nest is installed. The test of heat works fine, but when I’m out of test mode the boiler relays are not happy. There is no common ground wire, just a red and a white wire only. Is there a way to make this work properly, or is it incompatible with my system?

Hey Marcus571,

 

I would be more than happy to help you out. From what I can tell, there is a chance your system may not be compatible with the Nest Thermostat. If you are only showing the Red and White wire, I would recommend having a Nest Pro come out and take a closer look. They would be able to take a closer look at the system and install any wires that may need to be installed for the device to work. Please let me know if you have any other questions from here.

 

Best regards,

Jake
