System 2 and 4 - Electric air-source heat pumps shall be modeled with electric auxiliary heat and an outdoor air thermostat. The systems shall be controlled to energize auxiliary heat only when the outdoor air temperature is less than 40°F. The air-source heat pump shall be modeled to continue to operate while auxiliary heat is energized.
The rule logic does not include any logic pertaining to auxiliary heat. Data elements heatpump_auxilliary_heat_type, and heatpump_auxilliary_heat_high_shutoff_temperature are not used.
