OPERATION
Instructions relating to heating (*) are applicable only to "HEAT & COOL MODEL" (Reverse Cycle).
To Stop Operation
Press the START/STOP button.
The OPERATION indicator lamp (green) will go out.
Mode Operation
AUTO (in COOLING model):
When AUTO (automatic changeover) operation fi rst selected, the fan will operate at very low speed for about a few
●
minutes, during which time the indoor unit detects the room conditions and selects the proper mode.
Room temperature is higher than the defi ned temperature in temperature
setting → Cooling mode or dry mode
Room temperature is close to or lower than the defi ned temperature in
temperature setting → Monitor operation
When the indoor unit has adjusted your room's temperature to near the temperature setting, it will begin monitor opera-
●
tion. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently changes,
the indoor unit will once again select the appropriate operation (cooling) to adjust the temperature to the value set in the
temperature setting.
If the mode automatically selected by the unit is not what you wish, select one of the mode operation (COOL, DRY, FAN).
●
AUTO [in HEAT & COOL (Reverse Cycle) model]:
When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cooling or
●
heating) according to your room's present temperature.
● When AUTO 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 defined temperature in temperature
setting → 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 op-
●
eration. In the monitor operation mode, the fan will operate at low speed. If the room temperature subsequently chang-
es, the air conditioner will once again select the appropriate operation (heating, cooling) to adjust the temperature 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.
COOL: 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.

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.
