I have wires labeled. G, Y, Rh, R and W. Can I replace my honeywell labeled this way with a nest smart thermostat?

Hello lsmtairy,

Thanks for reaching out to the Community. I’m sorry for the delayed response here. I’d be happy to help you with your question.

If you have a jumper wire between the R and Rh wires, your system may be compatible with the Nest Thermostat, the Nest Learning Thermostat, and the Nest Thermostat E.

On the other hand, if you don’t have a jumper wire between the R and RH wires, your system may work with just the Nest Learning Thermostat.

You can use our handy compatibility checker tool to help determine if a Nest thermostat is compatible with your heating and cooling system.

Let me know if you have any questions.

All the best,

Lance
