Is this compatable??

[txredbird59]

Is this compatible with the learning thermostat? I do know it is a 2 stage system.

Looks like a Rheem Econet thermostat. E1 and E2 are a (proprietary) serial communication bus, talking to a controller in the furnace. Not going to work with a Nest (or another smart thermostat for that matter).

Hello folks,

Thanks for posting your thermostat wiring diagram. I'd be happy to take a look into this for you.

I appreciate your help here, @Zouf.

@txredbird59, to determine your system's compatibility with the Nest Thermostats. Could you also share with us a photo of your system's control panel showing how the wires from your thermostat are labeled? Also, what's the make and model of your HVAC system?

I'll look forward to your response.

Regards,

Mark
