Regarding the heating operation
G Heat pump type heating
Heat pump type heating means to heat the indoor air by utilizing the refrigerant to pick up the heat in the
outdoor air.
G Defrosting operation
When heating the indoor air with the heat pump type heating, frost will accumulate on the air inlet of the outdoor
unit as the outdoor temperature drops. Since the accumulated frost reduces the heating efficiency, the operation
is automatically switched to the defrosting mode. During the defrosting operation, the blowers on the both the
indoor and the outdoor units are stopped and the "HOT KEEP" message is displayed on the indication board.
G Outdoor air temperature and heating capacity
During the air conditioning by the heat pump type heating, the heating capacity drops along with the drop of the
outdoor air temperature.
Therefore, it is necessary to operate an additional heating equipment when the outdoor air temperature dropped
excessively.
G Necessary time to raise the indoor air temperature
Air conditioning by the heat pump type heating takes time a little longer because the entire air in a room is
heated by circulating hot air.
You should start the heating operation sufficiently earlier especially in a very cold morning.
