DESCRIPTION
COOLING
Cools, dehumidifies and filters the room air. Maintains desired room temperature.
FAN ONLY
Re-circulates and filters the room air. Maintains constant air movement in the room.
The appliance automatically selects the indoor fan speed in accordance to the room temperature. At the start, the appliance operates at high fan speed. As the room AUTO FAN temperature gets closer to the set temperature, the fan switches to a lower speed for quieter operation.(For Electronic Type)
FAN SPEED The appliance can set at different indoor fan motor speed by pressing the FAN HIGH SPEED button on the remote controller.(Only For Electronic Type) MEDIUM LOW
TEMP. SET UP DOWN
Press DOWN button once, the set temperature is decreased by 1℃. Press UP button once, the set temperature is increased by 1℃. (For Electronic Type)
TIMER
Automatically switches the appliance ON at preset time intervals, ensuring a comfortable environment before you return home, or switches OFF the appliance automatically when you sleep without wasting electricity. (For Electronic Type)
ENERGY SAVING
When the room temperature is higher than the setting temperature 2 ℃ , the compressor is on. When the room temperature is lower than the setting temperature, the compressor is off and the fan motor runs low speed.. When the room temperature is lower than 19℃, the unit turns off. (For Electronic Type)
