Wiring thermostat compatibility

[Joseph2]

Can’t tell if it’s compatible with current thermostat

If you need assistance for compatibility post a photo of the wiring for your current thermostat. Include additional helpful information like HVAC type and any peculiarities with your system.

You can also use the Compatibility Checker .

My wires to the Carrier thermostat are listed simply as W O G R C(blue) Y in that order. I have a Carrier heat pump system about 12 years old. How do I wire the Nest 3rd gen. when their letters are different (Y1, Y2, Rc, etc)?
