    2) Above characteristics indicates heat pump heating operation, which does not include elctric heater operation. 3) Because this air conditioner heats a room by drawing in the heat of the outside air (heat pump system), the heating efficiency will fall off when the outdoor temperature is very low, which consequently makes the room temperature decrease.
