We had a new Harmon Accentra installed this year and I'm attempting to install a wifi thermostat. I ran the line to the thermostat, bought an adapter for the c-wire and attempted to wire it up. When the thermostat is not "on" there a warning that the backup sensor is not detected. When the thermostat is on indicating heat is needed, the error goes away. Once thermostat turns off, the error returns but the stove continues to run. Any ideas? My connection involved just cutting one of the probe wires and wiring the thermostat in line. Did I miss something, should the stove not be in automatic? Thanks for the help!
