I tried setting up nest thermostat from my old lennox icomfort Wi-Fi
thermostat after setting it up the heating is not working. is it even
possible to set up nest thermostat from Lennox icomfort Wi-Fi?
Thermostat.
I have Nest Learning Thermostat - 3rd gen (latest). Location:
California(United States). It is connect to Wi-Fi and No errors are
showing up. Looks like it is not able to communicate to the HVAC.
