As soon as my Nest Thermostat is set onto the base the fan starts
running even if the unit is set to off. The thermostat was just
installed in place of another existing one. Heat Pump system. Trying to
run it on heat, compressor is running too.
So I got the heating to work. I have a 4th gen nest. There are no error
codes. Everything works but the fan runs nonstop. If I remove the Nest
from the base the fan shuts off.
