Compatibility and connection

[SandyLed]

How do I connect my wiring to the 3rd generation Nest thermostat?  

[Wondrack]

A. There are instruction included. 
b. You’re not compatible - like me - because of the V wire. 

[SandyLed]

Thanks for your reply but it’s a Y wire not a V wire.

A heating technician looked at my furnace and said the Nest is not compatible due to the O and B wires.

Hi folks,

I appreciate the help, @Wondrack.

@SandyLed, Thank you for taking the time to let us know about your inquiry. I did find a helpful article to identify a thermostat wire that would explain why Nest isn't compatible with your system.

Feel free to let us know if you have more questions in mind.

Best regards,

Mark
