Cooling in operation according to Remote Control setting. Time DelaySafety Control (3 minutes) 7 minutes TimeSave Control Starting Current Control Anti-Freezing Control • If the temperature of the indoor heat exchan ger falls continuously below 2°C for 4 minutes or more, the compressor turns off to protect the indoor heat exchanger from freezing. The fan speed setting remains the same. • Compressor will restart again when the indoor heat exchanger temperature rises to 10°C (Recovery). 3 minutes waiting of Time Delay Safety Control is valid for Cooling Operation. Compressor Reverse Rotation Protection Control 8 Operation Details 8.1. Cooling Mode Operation • W hen the compressor is stopped by Remote Control, it restarts after 3 minutes when it is turned ON by Remote Control. • W hen the setting temperature is reached during cooling operation, the compressor stops and it will not start for 3 minutes. • The compressor will start automatically if it has stopped for 7 minutes even if the room temperature is between the compressor ON temperature and OFF temperature. • W hen the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6 second later. • If the compressor is operating continuously for 5 minutes or longer and thetemperature differen ce between intake air and indoor heat exchan ger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically. (Time Delay Safety Control is valid) T = Intake air temperature - Indoor heat exchanger temperature This is to protect reverse rotation of the compressor when there is a instantaneous power failure. 17 CS-W7CKP CU-W7CKP 5 / CS-W9CKP CU-W9CKP 5 / CS-W12CKP CU-W12CKP5
Compressor Protection Control Automatic Fan Speed Mode • After the compressor starts for 50 seconds but the outdoor fan motor is still OFF, the compressor will stop and restart automatically. (Time Delay Safety Control is valid). • If the above phenomenon is repeated for 3 times, the compressor will stop totally. • The above phenomenon is reset when there is a change to heating mode or stopped by Remote Control Switch. WhenAutomatic Fan Speed is selected at Remote Control during cooling operation. • Fan speed rotates in the range of Hi to Me. • Deodorizing Control. 18 CS-W7CKP CU-W7CKP 5 / CS-W9CKP CU-W9CKP 5 / CS-W12CKP CU-W12CKP5

Quiet Operation Control (For Cooling Mode or cooling region of Soft Dry Mode) • Purpose of this operation is to provide quite cooling operation compare to normal operation. • W hen the Quiet Mode is set at the remote control, Quiet Mode LED illuminates, the sound level will be automatically decreased 2 dB (Lo), decreased 3 dB (Hi, Me), against the present sound level operation. • Quiet setting of fan speed rpm refer to Indoor Fan Speed Control. • Dew formation become severe at Quiet Lo cool, therefore Quiet Lo cool is operated only 1h 30 min (1h QLo, 30 min QLo + 50). After that, it goes back to Lo cool (However Quiet LED remains on). • Manual Airflow Direction:- − RPM control during Lo cool − RPM control during Hi & Me cool • Auto Airflow Direction:- • Quiet Mode Operation will stop if:- − Quiet mode button is pressed again. − Stopped by ON/OFF switch. − Timer OFF activates. − Powerful mode button is pressed. − W hen change mode to Air Circulation mode. 20 CS-W7CKP CU-W7CKP 5 / CS-W9CKP CU-W9CKP 5 / CS-W12CKP CU-W12CKP5
