Compatibility with Nest thermostat

[Jfcaron]

Looking to see if my system is compatible with a Nest thermostat:

I have a blue a white and a red wire ... no "C". No stranded wires, no 110/120 Volt label. Apparently I can't upload an image of my wiring setup.

Thanks,

John

Hi Jfcaron, 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. You may upload the image of your current thermostat wiring configuration to your Google Drive or Google Photos, then send the link to the file here. Make sure that you allow access to anyone with the link so I can view it from here. Also, you may use our compatibility checker to determine if a Nest thermostat is compatible with your system.

Keep us posted. We're happy to help. 

Best,

Zoe
