Nest wiring

[Krandol]

I have a geothermal unit that has a heat pump I have two wires left over on my new Nest Thermostat wiring block. A W-2 and a Y2 there's still one terminal left on the wiring block it's a star OB which one goes in it and what do I do with the other one. Thank you for any help. I posted this a couple weeks ago and I did not see a reply by the by the time I did it was too late to reply myself. I will attach pictures this time if I can figure it out thank you

Your system appears to only be compatible with the Nest Learning Thermostat. 3r Gen.

Post a picture of the original thermostat's wiring.

It doesn't look like it's going to allow me to post a picture that I've already taken. But it will allow me to post one that I take so when I get home tonight I will take another picture and send it to you

Yup, your system is not compatible with the Google Nest Thermostat, which is what they sent you.

Hiya Krandol,

Of course! In that case, I'll go ahead and lock this thread. If you have any issues with the new Thermostat when it arrives, please feel free to create a new thread.

Have a good one!

Best regards,

Jeran
