as shown in the diagram.
•
•
•
• The louver does not swing when the Indoor Fan Motor
stops during operation at the upper limit.
•
•
•
• When stopped with remote control, the discharge vent is
reset, and stopped at the closing position.
8.7. Vertical Airflow Direction Control
1. There is no swinging while indoor fan motor is stopped during Cooling and Soft Dry operation.
8.8. Delay ON Timer Control
•
•
•
• When the Delayed ON Timer is set by using the remote control, the unit will start operate slightly before the set time, so that
the room will reach nearly to the set temperature by the desired time.
•
•
•
• For Cooling and Soft Dry mode, the operation will start 15 minutes before the set time.
•
•
•
• For Automatic mode, the indoor fan will operate at SLo speed for 20 seconds, 15 minutes before the set time to detect the
intake air temperature to determine the operation mode. The operation indication lamp will blink at this time.
8.9. Remote Control Signal Receiving Sound
•
•
•
• Long beep sound will be heard when:-
−
−
−
− Stopping the Air Conditioner using ON/OFF switch.
•
•
•
• Short beep sound will be heard for others.
•
•
•
• To switch off the beep sound:-
Press the “Automatic Operation Button” continuously for 10 seconds or more (“beep” “beep” will be heard at the 10th second).
Repeat the above if you want to switch ON the beep sound.
However, if the “Automatic Operation Button” has been pressed the Automatic operation will be activated.
If you do not require this operation, you may change it by using the remote control.

9 Operation Details (CS-SC9CKH & CS-SC12CKH)
9.1. Cooling Mode Operation
•
•
•
• When the compressor is stopped by Remote Control, it restarts after 3 minutes when the Remote Control is turned ON.
•
•
•
• When 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.
•
•
•
• When 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 the temperature difference between intake air and
indoor heat exchanger is 2.5°C or less for 2 minutes, compressor will stop and restart automatically.

9.2. Random Auto Restart Control
•
•
•
• If there is a power failure during air conditioner operation, operation will be automatically restarted after 3 to 4 minutes when the
power is resumed.
It will start with previous operation mode and airflow direction.
•
•
•
• Restart time is decided randomly using 4 parameter:-
Intake air temperature, setting temperature, fan speed and Air Swing Blade position.
•
•
•
• This control can be omitted by open the circuit of JX2. (Refer Circuit Diagram)
