Compatibility

[cyndy]

Will the thermostat in this photo be compatible with the nest thermostat? Seems like two connected wires don't work with this system unless I can use the unconnected green one which is probably a ground and not a safe idea. Please advise. Thanks so much. Bought three of these and probably can't use. Can't seem to get picture up but will try again.

Hi cyndy,

Thanks for reaching out. Google Nest thermostats are designed to work with most 24 V systems, even older systems. They work with all common fuel types including natural gas, oil, and electricity. You can also click on this link to learn more about this.

Thanks,

Thanks for replying Edward, the video indicated I need a common wire and I only have two wires. Did you see the photo of my thermostat?

Hi cyndy,

Thanks for the response. Yes, I can see the photo of your thermostat and the unused green wire. Could you also check the control board of your HVAC system so we could check if the green wire is connected to a terminal?

Thanks,

Edward
