Google Nest Thermostat, am I missing a wire?

Krystian2 — Sat, 24 Feb 2024 21:51:22 GMT

Hi! I am trying to install my Nest Thermostat and I think I am missing the Y wire. My old thermostat has it but it was connected to the old thermostat box itself. Is this normal? What can I do? I also tried to connect a different yellow wire that was not previously connected to my thermostat but it doesn’t detect it either and gives me the N260 error. Thanks for your help!

Hi Krystian2,

Thanks for reaching out and for being a step ahead of us. I'd like to take a closer look at it. To confirm, in what country are you located? What is the make and model of your system? Please take a photo of the wires connected to your thermostat and to your system's control board. Ensure that the labels of the wires are visible.

For your reference, you can visit this support article about the N260 code.

Best,

Jenelyn
