Trane AC thermostat and Google Nest Compatibility

Community Member

I stepped through the Google Nest thermostat compatibility checker and it suggested that I present my question here.  The checker failed to confirm compatibility with my existing Trane thermostat since I could not indicate current use of a C (common) connection.  I believe the B (blue) will suffice as a common for the Google Nest. (Please see attached image.)  Can anybody confirm compatibility?  Thanks in advance for any input you might be able to offer.

Never mind.  I believe I have found the answer to my question elsewhere in the forum.

Specifically, here
