AUTO :
• When AUTO CHANGEOVER operation first
selected, the fan will operate at very low speed
for about one minute, during which time the unit
detects the room conditions and selects the prop-
er operating mode.
If the difference between thermostat setting and
actual room temperature is more than +2°C
Cooling or dry operation
When the outside temperature is lower than
10°C, cooling or dry mode operation is not per-
formed. Monitor operation

actual room temperature is within ±2°C
Monitor operation

operation
• When the air conditioner has adjusted your
room's temperature to near the thermostat set-
ting, it will begin monitor operation. In the moni-
tor 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 temperature to the value
set in the thermostat.
(The monitor operation range is ±2°C relative to
the thermostat setting.)
• If the mode automatically selected by the unit is
not what you wish, select one of the mode opera-
tion (HEAT, COOL, DRY, FAN).
About Mode Operation
Heating :
• Use to warm your room.
• When Heating mode is selected, the air condi-
tioner 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 provid-
ed to allow the indoor unit to warm up before
begin full operation.
• When the room temperature is very low, frost
may form on the outside unit, and its perfor-
mance 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 (red) will flash, and the heat operation will
be interrupted.
Cooling :
• Use to cool your room.
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.
Fan :
• Use to circulate the air throughout your room.
During Heating mode :
Set the thermostat to a temperature setting that is
higher than the current room temperature. The
Heating mode will not operate 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 temperature. The
Cooling and Dry modes will not operate if the ther-
mostat is set higher than the actual room tempera-
ture (in Cooling mode, the fan alone will operate).
During Fan mode :
You can not use the unit to heat and cool your
room.
