CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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°F to 86°F. • During cooling operation, the compressor will stop running and restart as shown in below figure. 8.1.1.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. • When operation begins, Soft Dry will be switched “ON” for a maximum 10 minutes, then Soft Dry operation will be turned “OFF” for a minimum 6 minutes.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. • Then, the unit start to operate at determined operation mode, until it is switched off using remote control, with the setting temperature as shown in below table.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 8.4. 8.4.1. Operation Control Restart Control (Time Delay Safety Control) • When 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. − Soft Dry operation - the compressor stops for 6 minutes (minimum) before resume operation.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. The fan speed setting remains the same. • This phenomenon is to protect the indoor heat exchanger from freezing and to prevent higher volume of refrigerant in liquid form returning to the compressor. • Compressor will restart again when the indoor heat exchanger temperature rises to 50°F (Recovery).
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU • 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 may occur at QLo cool, therefore QLo cool is operated only 1hr 30min (1 hr QLo, 30 min QLo + 80 rpm). After that, it operates at QLo + 160 rpm (However Quiet LED remains on). • Narrowing 1.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. Indoor Fan Speed Control • Indoor Fan Speed can be set using remote control. 8.5.1.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 8.5.2. Automatic Fan Speed Control • When 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. Indoor fan will rotate alternately between off and on as shown in below diagram. 2.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU • Auto Fan Speed during Soft Dry operation: 1. Indoor fan will rotate alternately between off and Lo-. 2. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing purpose. 3. When compressor at turn off condition for 6 minutes, indoor fan will start fan speed at Lo- to circulate the air in the room. This is to obtain the actual reading of intake air temperature. 8.5.3.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. • When Powerful operation is set, the setting temperature will be automatically decreased 5.4°F internally against the present setting temperature (Lower temperature limit: 60.8°F).
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. The sound level will reduce around 2 dB for Lo fan speed or 3 dB for Hi/Me fan speed against the present operation sound level.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. • To activate the previous timer setting, press SET button once again. • If main power supply is switched off, the timer setting will be cancelled. 8.11.1.
CS-C9DKU CU-C9DKU / CS-C12DKU CU-C12DKU 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. 1. Cooling and Soft Dry Mode • When the Economy Mode is set, the set temperature will be automatically increased 0.9°F against the present setting temperature.
