The auxiliary heat is turned off before the first stage of the thermostat is satisfied, so the heat pump continues to run. Since the refrigeration system can-not provide enough heat below the balance point to meet the load, the first stage heating thermostat will not be satisfied. The auxiliary heat will cycle on and off to maintain a temperature just below the thermostat set point.
