T is controlled by setting temperature up/down key of
remote control
2. COOL MODE : The unit operates according to the
difference between the setting and room temperature.
(18°C~30°C)
3. HEAT MODE(In case of Heat pump model) :
The unit operates according to the difference between the
setting and room temperature.(16°C~30°C)
*Prevention against cold wind : In order to prevent the
cool air from flowing out at the heat mode, the indoor fan
does not operate or operates very slowly in the following
cases. At this time, the indoor heat exchanger will be
preheating.
- For 3~5 minutes after the initial operation
- For deicing operation
- The operation of an indoor fan in accordance with the
temperature of an indoor heat exchanger
*High temperature release function : It is a function to
detect an outdoor overload by the sensor of an indoor
heat exchanger and to turn the outdoor fan or the
compressor ON/OFF for safety.
*Deice : Deicing operation is controlled by indoor unit's
heat exchanger temperature and accumulating time of
compressor's operation.
Deice ends by sensing of the processing time by deice
condition.
4. DRY MODE : Has 3 states, each determined by room
temperature.
The unit operates in DRY mode.
*Compressor ON/OFF Time is controlled
compulsorily(can not set up the fan speed, always
breeze).
*Protective function : Low temperature release.
(Prevention against freeze)
5. TURBO MODE : This mode is available in AUTO, COOL,
HEAT, DRY, FAN MODE.
When this button is pressed at first, the air conditioner is
operated "powerful" state for 30 minutes regardless of the

*In COOL mode : The setting temperature is automatical-
ly raised by 1°C each 1hour When the temperature has
been raised by total of 2°C, that temperature is
maintained.
*In HEAT mode : The setting temperature is automatically
dropped by 1°C each 1hour.
When the temperature has been dropped by total of 2°C,
that temperature is maintained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending on both the
difference between setting and the room temperature.
8. COMPULSORY OPERATION :
For operating the air conditioner without the remote
control.
*The operating is the same function that AUTO MODE in
the remote control.
9. SWING : BLADE-H is rotated vertically by the stepping
