About Mode Operation
AUTO:
COOLING MODEL
● When the room temperature is 2 °C higher than the set temperature, the mode
will switch between Cooling and Drying.
● During the Drying mode operation, the FAN setting should be switched to LOW
for a gently cooling effect during which the fan may temporarily stop rotating.
● If the mode automatically selected by the unit is not satisfactory, see page 7 for
instructions on changing the mode setting (COOL, FAN).
AUTO (* AUTO CHANGEOVER):
HEAT & COOL MODEL (Reverse cycle)
● When AUTO CHANGEOVER is selected, the air conditioner selects the appropriate operation mode (Cooling or Heating)
according to your room's present temperature.
● When AUTO CHANGEOVER is first selected, the fan will operate at very low speed for about one minute while the unit
determines the current conditions of the room and accordingly selects the proper operation mode.
● When the air conditioner has adjusted your room's temperature to near the thermostat 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
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 satisfactory, see page 7 for instructions on changing the mode setting
(HEAT, COOL, FAN).
● Do not select AUTO CHANGEOVER if the difference in the environmental temperatures of the master and slave units is over
2 °C. (Otherwise, the indoor fan may not be controlled correctly.)
* Heating:
● 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 selected fan set-
ting. This period of time is provided 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 performance may be reduced. In order to remove such frost, the unit will
automatically enter the defrost cycle from time to time. During defrosting (see
page 24), the heating mode will be temporarily interrupted. DEFROST will be
shown on the remote controller display **and indoor unit's OPERATION indica-
tor lamp (red) will flash.
Cooling:
● Use to cool your room.
Fan:
● Use to circulate the air throughout your room.

Setting temperature
* 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 mode:
Set the thermostat to a temperature set-
ting that is lower than the current room
temperature. The Cooling mode will not
operate if the thermostat is set higher than
the actual room temperature (in Cooling
mode, the fan alone will operate).
