New Install Compatability

[seventhree]

I have a brand new American Standard heat pump with variable speed fan.  I have 8 wires and the nest only has 6 connection points.  Will this thermostat not work?

Current config:

Blue Wire to C

Red Wire to R

White Wire to W1

Black Wire to W2

Orange Wire to 0/B

Green Wire to G

Yellow Wire to Y1

Brown Wire to BK

Hi seventhree, 

Thanks for posting here in the Community forum and for showing interest in our Nest Thermostats. Basing on the majority of your thermostat wires, I can confirm that it could be compatible with our Nest Learning Thermostat 3rd generaytion. However, we're unsure of the BK in your American Standard heat pump system since it is not listed as a common Nest Thermostat wire. Therefore, you may need to contact a pro to check compatibility and have your thermostat installed. You can check this link to know more about identifying a thermostat wire. 

Keep us posted.

Best,

Zoe
