Hello,

The compatibility checker sent me this way. Couldn’t find much out there on this combination- any help would be great! Thanks!

Hello Csh2000, 

Thank you so much for posting in this community. I understand that you have some concerns regarding whether your wiring system is compatible with our thermostat's model. Don't worry, it’s a pleasure to be able to assist you.

To provide you with accurate information, please help me out by answering the following question: 

• What HVAC system do you have in your home?

• Could you check where the blue wire comes from in your system’s control board?

• Have you acquired a Nest Thermostat? If so, which is the model? For your reference, you can consult this article: How to tell which Nest thermostat you have.

Any additional details you can provide will be helpful.

Regards,

Daniel

Looks like you might have an old Trane heat pump.

Try this wiring,

White - W to W

Blue - B to C

Green - G to G

Red - R to R

Black - O to */OB

Yellow - Y to Y
