Hello. I have the above wiring. R = red wireI+ = green wireI- = brown
wireW = white wireCan someone guide me to the compatible Nest wiring I
would need. 4 wire to Nest. Thank you.
Thank you everyone. I did call an HVAC technician who had to work from
the control panel downstairs before installing the Nest. Worth the price
of a service call. 45 minutes labour. Thanks again.
