Since the air conditioner carries out the heating operation by drawing on the heat of the outside air (through
heating pump), the heating capacity may decrease if the temperature outside the room is too low. If the
heating effect is not so satisfying, use some other heating device together.
·
Anti-freezing function during cooling
When the temperature of the air from the indoor outlet is too low, the unit will run for some time under the
fan mode, to avoid frost or ice forming in the indoor heat exchanger.
·
Cold air prevention
In several minutes after the heating mode is started, the fan of the indoor unit will not run until the heat
exchanger of the indoor unit reaches a high enough temperature. That is because cold air prevention system
is operating.

When the outdoor temperature is too low, frost or ice may form in the outdoor heat exchanger, reducing
heating performance. When this happens, a defrosting system of the air conditioner will operate. At the same
time the fan in the indoor unit stops(or runs at a very low speed in some cases), a few minutes later, the
defrosting is over, and the heating operation restarts.
