The OPERATION indicator lamp will go out.
MODE Operation
● When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling or
AUTO:
heating) according to your room's present temperature.
● When AUTO (automatic changeover) operation fi rst selected, the fan will operate at low speed for about a few
minute,during which time the indoor unit detects the room conditions and selects the proper operation mode.
Room temperature is higher than the defi ned temperature in temperature
setting → Cooling mode or dry mode
Room temperature is close to the defi ned temperature in temperature set-
ting→ Determined by outdoor temperature
Room temperature is lower than the defi ned temperature in temperature
setting → Heating mode
● When the air conditioner has adjusted your room's temperature to near the thermostat setting, it will begin monitor
operation. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently
changes, the air conditioner will once again select the appropriate operation (heating, cooling) to adjust the tempera-
ture to the value set in the thermostat.
● If the mode automatically selected by the unit is not what you wish, select one of the mode operation (HEAT, COOL, DRY, FAN).
HEAT: ● Use to warm your room.
● 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 se-
lected fan setting. This period of time is provided to allow the indoor unit
to warm up before beginning full operation.
● 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 indicator lamp
will fl ash,and the heat operation will be interrupted.
● After the start of heating operation, it takes some time before the room
gets warmer.
● Use to cool your room.
COOL:
● During cooling mode, the indoor unit's fan may stop from time to time.
(Indoor unit fan control for energy saving)
DRY: ● Use for gently cooling while dehumidifying your room.
● 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 adjusting room humidity.
● The fan speed cannot be changed manually when Dry mode has been selected.
● Use to circulate the air throughout your room.

Heating
During Heating mode:
Set the thermostat to a temperature setting
that is higher than the current room tem-
perature. The Heating mode will not oper-
ate if the thermostat is set lower than the
actual room temperature.
During Cooling/dry mode:
Set the thermostat to a temperature setting
that is lower than the current room tem-
perature. The Cooling and dry modes will
not operate if the thermostat is set higher
than the actual room temperature (in Cool-
ing mode, the fan alone will operate).
During Fan mode:
You can not use the unit to heat and cool
your room.
Indoor unit fan control for energy sav-
ing:
With stopping rotation of the indoor unit fan
when the outdoor unit is stopped, it ena-
bles power-saving operation.
In initial setting, this function is activated.
To inactivate the function, consult the in-
staller or authorized service personnel.
Even if the setting is changed, if the fan
speed in cooling or dry operation is set to
"AUTO", this function still works to sup-
press the diffusion of circulated indoor hu-
midity.
