Nest pro wiring help

where do I connect my X2 O T U F B wires on my nest pro thermostat when I only see Y C W G R OB outlets

Hey there,

Thank you for posting here. The wire for X2, O, T U and F 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.

Check out this link for more details.

Regards,

Ryan
