Operating Instructions

2-1-1 Name & Function of Key in remote control

1. AUTO MODE : In this mode, operation mode(COOL, HEAT) is selected automatically by the room temperature of initial operation.

Room Temp Tr≥ 21°C+∆T 21°C +∆T>Tr

∆T= -1°C, -2°C, 0°C+1°C+2°C ∆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 : 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

The temperature of

indoor heat exchanger

28˚C~below 34˚C

34˚C~below 40˚C

*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.

Cool Operation (Set Temp:24˚C+∆T) Heat Operation (Set Temp:22˚C+∆T)

Setting Speed

*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 set temperature, room temperature. When this button is pressed again, or when the operating time is 30 minutes, turbo operation mode is canceled and returned to the previous mode. *But, if you press the TURBO button in

DRY or FAN mode that is changed with AUTO mode automatically.

6. SLEEP MODE : Sleep mode is available only in COOL or HEAT mode. The operation will stop after 6 hours. *In COOL mode : The setting temperature

is automatically 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.

Operating Instructions

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 air conditioner starts up in the most

suitable mode for the room temperature:

Room Temperature

Less than 21ûC

21ûC or above

Operating Mode

Heat Cool

Temperature Setting

22ûC approx. 24ûC approx.

9. SWING : BLADE-H is rotated vertically by the stepping motor. *Swing Set : Press the button under the

remote control is displayed on LCD the

and the blades move up and down. If the one more time press the button, blades location is stop.

10. SETTING THE ON/OFF TIMER. : *ON TIMER : The On Timer enables you
