Hey YD,

I am sorry for the late response. I wanted to follow up with you, and see if you still needed any help with the wiring on your thermostat. Please let me know if I can be of any help.

Best regards,

Yes, I am stilling needing help. There are two wires in the Y in my Honeywell thermostats. Not sure if I can put two wire in the Y on the nest.

Hey YD,

Glad to be of help, and sorry to hear you are still having trouble. You will only want 1 wire in the Y spot on the Nest Thermostat. Do you mind me asking if you have access to your HVAC system’s control board? This usually provides more details on what the wire is in control of. You can follow the article here, and it should help you identify both wires. You can also have a Nest Pro come out and take a closer look. They would be able to install the device and ensure it is working properly. Please let me know if the article helped, or if you are still having trouble finding out the wire label.

Best regards,

Jake
