2nd Gen Nest Thermostat

[JcKobeLiam]

Good day. I have a goodman furnace and centralized AC. I wanted to install a nest thermostat. Hope someone can give me a hand with the wiring. 

My current setup is a Comfortzone. Talked to an agent we already figured out the common wire, Y and R Wire but there is one black wire that was marked "1". I have attached both my wiring and my thermostat board. 

Thanks so much.

Hey there,

Thank you for posting here. The label 1 indicates that this is a proprietary type of HVAC system. Proprietary systems aren’t compatible with Google Nest thermostats. However, some proprietary systems can be rewired by a pro installer to be compatible.

Regards,

Ryan
