Nest thermostat compatiblity

[StevenS]

I have a Lennox heat pump and air handler with an icomfort thermostat. The wiring on the icomfort thermostat has 4 wires labeled  ( R i+ i- C ). Same in the air handler control board. No orange, blue wires. Not sure what to do next.

Hey there StevenS, 

I can definitely understand the confusion when it comes to thermostat issues as it can be very odd to figure out sometimes, but I'm happy to look into this for you. 

First off, I would suggest using the Compatibility Checker to see if your system is compatible. Then, if it is, I would suggest contacting a pro to come out to help you with this since I know that the Nest thermostat is not compatible with stranded wires, every wire has to be connected to the Nest Thermostat system.

Please let me know if you have any further questions or concerns. 

Best regards, 

Garrett DS
