About Mode Operation
Heating:
Use to warm your room.
When Heating mode is selected, the indoor unit will operate at very low
fan speed for about 3 to 5 minutes, after which it will switch to the selected
fan setting. This period of time is provided to allow the indoor unit to warm
up before begin full operation.
When the outdoor temperature is very low, frost may form on the outdoor
unit, and its performance may be reduced. In order to remove such frost,
the air conditioner will automatically enter the defrost cycle from time to
time. During Automatic Defrosting operation, the OPERATION Indicator
Lamp will ash, and the Heat operation will be interrupted.
After the start of Heating operation, it takes some time before the room
gets warmer.
Cooling:
Use to cool your room.
Dry:

You cannot heat the room during Dry mode.
During Dry mode, the indoor unit will operate at low speed; in order to ad-
just room humidity, the indoor unit’s fan may stop from time to time. Also,
the fan may operate at very low speed when adjusting room humidity.
The fan speed cannot be changed manually when Dry mode has been
selected.
