Compatibility

Hi,

I currently have a IQ Drive thermostat. I also opened up the furnace and took a picture of the wiring which has the following:

R - C - DX+ - DX-

4 wire connection.

Please advise if this is compatible with the nest thermastat.

thank you

Your current thermostat uses a proprietary interface that is not compatible with any of the Nest thermostats.

Sometimes the control board will also have a terminal with the standard control wires. If there is one, then it would be compatible.

Thank you for the response.

Am I able to swap the current circuit board with another to support the nest thermostat?
