1.Is this connected to a heat pump outside?

2.If so is the outdoor coming on

3.Do you see EM Heat or AUX heat on thermostat?

Customer: replied 1 year ago.
I don't it is connected to an outside heat pump. It is sort of warm air. Not like it is normally. No EM or aux heat on the thermostat. Just auto or on

Do you have a multi meter for troubleshooting?

Also just to make certain about the het pump give me model on your outdoor unit. Looks like the heat kit is only 5KW
