Mode operation
AUTO (in COOLING model):
When AUTO (automatic changeover) operation first selected, the fan will operate at very low speed for about a few
l
minutes, during which time the indoor unit detects the room conditions and selects the proper mode.
Room temperature is higher than the defined temperature in
temperature setting → Cooling mode or dry mode
Room temperature is close to or lower than the defined temperature
in temperature setting → Monitor operation
l When the indoor unit has adjusted your room's temperature to near the temperature 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 indoor unit will once again select the appropriate operation (cooling) to adjust the temperature to the
value set in the temperature setting.
l
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]:
l When AUTO (automatic changeover) is selected, the air conditioner selects the appropriate operation mode (cool-
ing or heating) according to your room's present temperature.
When AUTO operation first selected, the fan will operate at low speed for about a few minute, during which time the
l
indoor unit detects the room conditions and selects the proper operation mode.
Room temperature is higher than the defined 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 defined temperature in
temperature setting → Heating mode
l
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 tem-
perature to the value set in the thermostat.
l
If the mode automatically selected by the unit is not what you wish, select one of the mode operation (HEAT,
COOL, DRY, FAN).
l
HEAT*: Use to warm your room.
l 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 beginning full operation.
l
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 unit will automatically enter the defrost cycle from time to
time. During automatic defrosting operation, the heat operation will be
interrupted.
l After the start of heating operation, it takes sometime before the room
gets warmer.
l
COOL: Use to cool your room.
l
DRY: Use for gently cooling while dehumidifying your room.
l You cannot heat the room during dry mode.
l
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.
l The fan speed cannot be changed manually when dry mode has been
selected.
FAN: l Use to circulate the air throughout your room.

During heating* mode:
Set the thermostat to a temperature set-
ting 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 set-
ting that is lower than the current room
temperature. The cooling and dry modes
will not operate if the thermostat is set
higher than the actual room temperature
(in cooling mode, the fan alone will ope-
rate).
During fan mode:
You can not use the unit to heat and cool
your room.
