8 Operation Details
8.1. Cooling Mode Operation
Cooling in operation according to Remote Control setting.
Time Delay Safety Control (3 minutes)
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.
7 minutes Time Save Control
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.
Starting Current Control
When the compressor outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will operate 1.6
second later.
Anti-Freezing Control
If the temperature of the indoor heat exchanger 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
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. (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.
Anti-Dew Formation Control
Purpose is to prevent dew formation on indoor unit air discharge area.
When the following conditions accur for 30 minutes continuously, anti-dew formation is controlled by indoor fan speed shift to
low (CLo to HLo):
Indoor intake air temperature is more than 24°C and less than 30°C.
Remote Control setting temperature is less than 25°C.
Compressor is on.
Cooling operation mode.
Indoor Fan motor operate at Low fan speed.
This control is cancelled immediately when above condition is changed.
17
CS-C12BKPG CU-2C24BKP5G / CS-C14BKPG CU-2C23BKP5G / CS-C9BKPG
Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during cooling operation.
Fan speed rotates in the range of Hi to Me.
Deodorizing Control.

CS-C12BKPG CU-2C24BKP5G / CS-C14BKPG CU-2C23BKP5G / CS-C9BKPG
8.2. Soft Dry Mode Operation
The unit starts cooling operation until the room temperature reaches the setting temperature set on the Remote Control, and
then Soft Dry operation will start. During Soft Dry operation, the Indoor Fan will operate at SLo speed.
The operation will be switched on and off for up to 10 minutes ONand 6 minutes OFF. Once Soft Dry operation is turned
off, it stops for 6 minutes.
Time Delay Safety Control
Once the compressor stops, it will not start for 3 minutes during Cooling operation.
Starting Current Control
Same as Starting Current Control for Cooling Mode operation.
Anti-Freezing Control
Same as Anti-Freezing Control for Cooling Mode operation. (For Soft Dry region, 6 minutes waiting is valid during compressor
stops.)
Compressor Reverse Rotation Protection Control
Same as Compressor Reverse Rotation Protection Control for Cooling Mode Operation. (For Soft Dry region, 6 minutes waiting
is valid during compressor stops.)
Anti-Dew Formation Control
Same as Anti-Dew Formation Control for Cooling Mode operation.
Automatic Fan Speed Mode
When Automatic Fan Speed is selected at Remote Control during Soft Dry operation.
Fan speed off and on at SLo speed.
Deodorizing Control.

8.3. Air Circulation Mode Operation
When the temperature near the ceiling reaches the setting temperature, Air Circulation Mode operation commences at low
airflow volume. It stops when the temperature drops to 2°C below the setting temperature.
Air Circulation Mode Operation Time Diagram
8.4. Automatic Mode Operation
Standard for Determining Operation Mode
Indoor fan operates at SLo fan speed for 25 seconds.
After judging indoor air temperature, the operation mode is determined and operation continued at the mode determined.
After the operation mode has been determined, the mode does not change. However, Soft Dry mode operation includes
Cooling mode operation. Room temperature adjustment.
The following are added to the setting temperature specified as above.
The mode judging temperature and standard setting temperature can be increased by 2°C, by open the circuit of JX1 at indoor
electronic controller.
