l
When AUTO CHANGEOVER is fi rst selected, the fan will
operate at a very low speed for about 1 minute while the
unit determines the current conditions of the room and
selects the proper operation mode.
If the difference between thermostat setting and actual
room temperature is more than +2 °C

OPERATING TIPS
Mode operation: AUTO
About Mode Operation
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.
* Heating:
l
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 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 heat operation will
be interrupted.
l
After the start of heating operation, it takes sometime before the room
gets warmer.
Cooling:
l
Use to cool your room.
Dry:
l
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.
COOLING MODEL
l
When the room temperature is 2 °C higher than the set
temperature, the mode will switch between Cooling and
Drying.
l
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.
l
When the room temperature is near the thermostat set-
ting, the air conditioner will begin monitor operation. In
the monitor operation mode, the fan will operate at a
very low speed. If the room temperature subsequently
changes, the air conditioner will once again select the
appropriate operation (Heating or Cooling) to adjust
the temperature to the value set in the thermostat. (The
monitor operation range is ±2 °C relative to the thermostat
setting.)
