I have a Trane ac/heat pump that has a 7 wire connection. The nest app
says not compatible but my AC server says it is but wants to charge 500
to install 1 of my 2 thermostats. Please help me know how to connect it.
See photo.
Thanks. Edward. After doing some research I figured out which wire went
where and it is working perfectly. I have 3rd gen learning thermostat.
See photo of correct wiring which may help others. Thanks!
