• The cooling preset temperature is greater than the heating preset temperature.
• The difference between the cooling and heating preset temperatures is equal or greater than the minimum temperature difference that varies depending on the indoor
unit model to be connected.
The settable temperature range varies with the model of outdoor units and remote controller.
Note:
Even if you press the ON/OFF button immediately after shutting down the operation is progress, the air conditioner will not start for about 3 minutes.
This is to prevent the internal components from being damaged.

The mode icon will blink when other indoor units in the same refrigerant
system (connected to the same outdoor unit) are already operated in a
different mode. In this case, the rest of the unit in the same group can
only be operated in the same mode.

During heating mode, the air conditioner stops before the set room tem-
perature is reached. When the outdoor temperature is low and the humidity is high, frost
may form on the outdoor unit. If this occurs, the outdoor unit performs
a defrosting operation. Normal operation should begin after approxi-
mately 10 minutes.

A cracking or creaking sound is heard. These sounds can be heard when parts rub against each due to ex-
pansion and contraction from temperature changes.
The room has an unpleasant odor. The indoor unit draws in air that contains gases produced from the
walls, carpeting, and furniture as well as odors trapped in clothing, and
then blows this air back into the room.
A white mist or vapor is emitted from the indoor unit. If the indoor temperature and the humidity are high, this condition may
occur when operation starts.
