Bryant Plus 90i Dual Fuel system

I am trying to connect the Nest Thermostat. Current thermostat is a Honeywell. See picture. Wondering if the B wire is actually the C common wire.

Hello hauser775,

Thanks for reaching out about your systems' compatibility with the Nest Thermostats. I'd be happy to take a look at this for you.

It appears that your heat pump system wiring setup is compatible. The blue wire would be your 24 V common. So, you should connect it to the C terminal for the Nest Thermostat. Also, please follow these guides for your wiring configuration so you have a reference:

W/W1 (white)
Y/Y1 (yellow)
R/Rc (red)
G (green)
O/B (orange)
C (blue)

Let me know if you need more help.

Best regards,

Mark
