8 Operation Details 8.1. Cooling Operation • Cooling operation can be set using remote control. • This operation is applied to cool down the room temperature reaches the setting temperature set on the remote control. • The remote control setting temperature, which takes the reading of intake air temperature sensor, can be adjusted from 60.
8.2.1. Soft Dry Operation Time Diagram 8.2. Soft Dry Operation • Soft Dry operation can be set using remote control. • Soft Dry operation is applied to dehumidify and to perform a gentle cooling to the room. • This operation starts when the intake air temperature sensor reaches the setting temperature on the remote control.
8.3. Automatic Operation • Automatic operation can be set using remote control. • This operation starts to operate with indoor fan at SLo speed for 20 seconds to judge the intake air temperature. • After judged the temperature, the operation mode is determined by referring to the below standard.
8.4. Operation Control 8.4.1. Restart Control (Time Delay Safety Control) • W hen the thermo-off temperature (temperature which compressor stops to operate) is reached during:- − Cooling/Heating operation - the compressor stops for 3 minutes (minimum) before resume operation.
8.4.5. Anti-Freezing Control • If the temperature of the indoor heat exchanger falls below 35.6°F continuously for 4 minutes or more, the compressor turns off.
• Anti-Dew Formation is control by:- • Increasing Air Flow Volume 1. Lo fan speed. Lo fan speed is changed to Lo+ after 30 min to prevent dew formation. 2. QLo fan speed. Dew formation m ay occur at QLo cool, therefore QLo cool is operated only 1hr 30min (1 hr QLo, 30 min QLo + 80 rpm).
During Anti-Dew condensation prevention, Airflow Direction Manual Control angle change from 10°, 15°, 20°, 26°, 32° to 22°, 24°, 26°, 28°, 30°.
8.5.2. Automatic Fan Speed Control • W hen set to Auto Fan Speed, the fan speed is adjusted between maximum and minimum setting as shown in the table. − Fan speed rotates in the range of Hi and Me. − Deodorizing Control will be activated. • Auto Fan Speed during cooling operation: 1.
• W hen the vertical airflow direction is set to Auto using the remote control, the louver swings up and down as shown in the diagram. • W hen stop operation using the remote control, the discharge vent is reset, and stop at the closing position.
8.8. Horizontal Airflow Direction Control • The horizontal airflow direction louvers can be adjusted manually by hand. 8.9. Powerful Operation • The Powerful operation is to achieve the setting temperature quickly. • W hen Powerful operation is set, the setting temperature will be automatically decreased 5.
8.10. Quiet Operation (For Cooling Operation or cooling region of Soft Dry Operation) • The Quiet operation is to provide quiet/cooling operation condition compare to normal operation. • Once the Quiet Mode is set at the remote control, the Quiet Mode LED illuminated.
8.11. Timer Control • There are 2 types of timer, ON and OFF timer. • Both ON and OFF timer can be set by pressing ON or OFF button respectively. • By pressing ON/OFF operation button, ON Timer or OFF Timer will not be cancelled. • To cancel the previous timer setting, press CANCEL button.
8.14. Economy Mode Operation • Purpose of this operation is to save or reduced electrical power consumption of the room air conditioner. However consumer is advised to use Economy Mode operation after the room temperature reaches the desired temperature.
