About Mode Operation
G
AUTO: Depending on the room temperature at the time operation begins, the
operating mode will be switched automatically as shown in the
accompanying table.
Also, depending on the operating mode, the room temperature setting
will cause the "standard" temperature to be set as shown.
Actual Room
Temperature
30°C or above
27°C-30°C
25°C-27°C
22°C-25°C
Below 22°C
The operating mode and standard thermostat settings are selected auto-
matically when operation begins.
G
When automatic operation is initiated, the fan will run at very low speed
for about one minute while the unit detects and selects the proper op-
erating mode.
G
Once the operating mode has been set, the mode will not change even
if the room temperature changes.
However, during the monitor operation mode, if the room temperature
changes to below 22°C, the mode will automatically switch to Heat,
and when it rises above 25°C the mode will automatically switch to
Dry.
G
When in the monitor mode, the fan will operate very slowly.
G
If the START/STOP button is pressed to recommence operation within
two hours after stopping automatic operation, the unit will begin oper-
ating from the same mode as before.
G
Heating: Use to warm your room.
G
When Heating mode is selected, the air conditioner 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.
G
When the room temperature is very low, frost may form on the outside
unit, and its performance may be reduced. In order to remove such
frost, the unit will automatically enter the defrost cycle from time to
time. During Automatic Defrosting operation, the OPERATION indica-
tor Lamp (red) will flash, and the heat operation will be interrupted.
G
Cooling: Use to cool your room.
G
Dry: Use for gently cooling while dehumidifying your room.
G
You cannot heat the room during Dry mode.

During Dry mode, the unit will operate at low speed; in order to adjust
room humidity, the indoor unit's fan may stop from time to time. Also,
the fan may operate at very low speed when detecting room humidity.

The fan speed cannot be changed manually when Dry mode has been
selected.
