O- Orange

R- Red

Y1- Yellow

E/W1-- Brown

C- Blue

G- Green

W2- White

Please advise the proper wiring setup

I am sorry to barge in on someone else's post, but I didn't see how to start a new post. Mea Culpa. That said, the above Honeywell Color thermostat is attached to my US, heat pump/A/C. It is a Trane American Standard unit. On the Honeywell w and o/b are one terminal. On the Nest they are separate. In any case the heat doesn't work with the orange wire in O/B regardless of whether I've selected 'O' or 'B'

Again, sorry for interrupting a thread, but can you help please?

Psloss

Hi @psloss

I'm really sorry that you are having this type of issue with your Nest Thermostat and I apologize for the long time it took for you to get a response. If you still need assistance I will need some additional information from you that would be best shared privately.

I'm sharing a link to a form for you to fill out so we can look into this further. This form is only meant for you to use, so let me know once you're done.

All the best,

Josh
