We have a Nest thermostat that we use to remotely control our vacation house HVAC, as we aren’t there for weeks at a time.
tonight, for no reason, the thermostat displayed ERROR on my app. It says Error e79. But nobody has even been there, Nothing has been changed or altered, and the thermostat has worked perfectly for the last 2+ years.
is there anything we can do remotely to figure out the issue? Is the thermostat still working locally? Or is the entire heating system offline as well?
