NEST Thermostat Functioning Well after Wiring Change
NEST Thermostat Functioning Well after Wiring Change:
Over a month on since I changed my NEST v1 thermostat wiring to include the “C” or 24Vac Common wire, it is working flawlessly again. We have had several cycles of cold (-20C) and warm (+8C) and there have been no problems with charge levels, network communication or connectivity.
I wonder why NEST does not strongly recommend the use of the “C” wire when it is so simple to install? BTW, if you are looking for a wiring diagram of your furnace and controller, check the back side of the access panel (Doh!!) on the furnace; it should be there.
I have e found a couple of very useful links for anyone in a similar situation and seeking a solution:
