Was informed heat strips didn’t work. Turned on emergency heat at thermostat. Tested amp draw on both 5KW sections both drawing 20 A switched it off at the thermostat several times and retested with the same results. Took a temperature difference on the heat strips 20°. Tested heat pump and auxiliary heat at the same time. Auxiliary heat doesn’t come out with the heat pump with a 10° setpoint. Thermostat should be turning on the auxiliary heat at 2° below set point or more this thermostat needs to be replaced
