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 16°C
to 30°C.
• During cooling operation, the compressor will stop running and restart as shown in below figure.
8.1.1. Cooling Operation Time Diagram
16
CS-V18DKE CU-V18DKE / CS-V24DKE CU- V24DKE
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. After that, the Soft Dry operation will be “ON” and “OFF” based on the setting temperature as shown
in below figure.
• However after 3 minutes of compressor off, during Soft Dry “OFF” (within 6 minutes Soft Dry restart control), the indoor unit will
start to operate at normal Cooling mode if the intake temperature is higher than Cooling “ON” point.
8.2.1. Soft Dry Operation Time Diagram
17
CS-V18DKE CU-V18DKE / CS-V24DKE CU- V24DKE
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.
• The setting temperature for all the operations can be changed one level up or one level down from the standard temperature
as shown in below table by pressing on the temperature up or temperature down button at remote control.
Operation Hi (Standard) Lo
(+2°C) (±0°C) (-2°C)
Cooling 27°C 25°C 23°C
Soft Dry 24°C 22°C 20°C
• The operation mode judging temperature and standard setting temperature can be increased by 2°C permanently, by open the
circuit of JX1 at indoor electronic controller.
8.4. Operation Control
(For 8.5.1 to 8.5.7 information applies only to Cooling and Soft Dry Operation)
8.4.1. Restart Control (Time Delay Safety Control)
• When the thermo-off temperature (temperature which compressor stops to operate) is reached during:-
− Cooling operation - the compressor stops for 3 minutes (minimum) before resume operation.
− Soft Dry operation - the compressor stops for 6 minutes (minimum) before resume operation.
• If the operation is stopped by the remote control, the compressor will not turn on within 3 minutes from the moment operation
stop, although the unit is turn on again within the period.
• This phenomenon is to balance the pressure inside the refrigerant cycle.
8.4.2. 60 Seconds Forced Operation
• Once the air conditio ner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intake
air temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at the
remote control is permitted.
• The reason for the compressor to force operate at minimum 60 seconds is to allow the refrigerant oil run in a full cycle and
return back to the outdoor unit.
18
CS-V18DKE CU-V18DKE / CS-V24DKE CU- V24DKE
8.4.3. 7 Minutes Time Save Control
• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between the
compressor ON temperature (A) and compressor OFF temperature (B) during the period.
• This phenomenon is to reduce the built up humidity inside a room.
8.4.4. Anti-Freezing Control
• If the temperature of the indoor heat exchanger falls below 2°C 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 exchan ger 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 10°C (Recovery).
• Restart control (Time Delay Safety Control) will be applied in this Control if the recovery time is too short.
8.4.5. 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 continuous 2 minutes, compressor will stop and restart automatically.
• Time Delay Safety Control is activated before the compressor restart.
▲ T = Intake air temperature - Indoor heat exchanger temperature
• This is to prevent compressor from rotate reversely when there is an instantaneous power failure.
8.4.6. Starting Current Control
• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start to
operate at 1.6 second later.
• The reason of the difference is to reduce the starting current flow.
19
CS-V18DKE CU-V18DKE / CS-V24DKE CU- V24DKE
8.4.7. Anti-Dew Formation Control
• Purpose is to prevent dew formation on indoor unit air discharge area.
• The following conditio ns occur for 30 minutes continuously, anti-dew formation will activate:
− Remote Control setting temperature is less than 25°C.
− Compressor is on.
− Cooling operation mode.
− Indoor fan motor operate at low fan speed or QLo.
• This control is cancelled immediately when above condition is changed.
• Anti-Dew formation is control by:
1. Lo fan speed
Lo fan is changed to Lo+ fan
2. QLo fan speed
8.5. Indoor Fan Speed Control
• Indoor Fan Speed can be set using remote control.

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 and Lo-.
− 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. At the beginning of each compressor start operation, indoor fan will increase fan speed gradually for deodorizing purpose.
3. For the first time the compressor operate, indoor fan will be switched to Hi fan speed from Lo- after 70 seconds from the
start of compressor. This cause the room temperature to achieve the setting temperature quickly.
4. During compressor stop, indoor fan will operate at Lo- for the beginning 20 seconds to prevent higher volume of refrigerant
in liquid form returning to the compressor.
5. After the compressor at turn off condition for 3 minutes, indoor fan will start to operate at Lo- to circulate the air in the room.
This is to obtain the actual reading of the intake air temperature.
6. When the compressor resume operation, indoor fan will operate at Me fan speed (after 70 seconds from the restart of
compressor) to provide comfort and lesser noise environment.
21
CS-V18DKE CU-V18DKE / CS-V24DKE CU- V24DKE
• 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. Manual Fan Speed Control
• Manual fan speed adjustment can be carried out by using the Fan Speed selection button at the remote control.
• There are 3 types of fan speed settings: Lo, Me, Hi.
8.6. Outdoor Fan Speed Control
• There is only one speed for outdoor fan motor (V18DK).
• There is 2 speed for outdoor fan motor, outdoor fan speed can be changed to Hi or Lo according to outdoor temperature
(V24DK).
• When the air conditioner is turned on, the compressor and the outdoor fan will operate simultaneously .
• Likewise, both compressor and outdoor fan will stop at the same time if the unit is turned off.
8.7. Vertical Airflow Direction Control
8.7.1. Auto Control
(Cooling and Soft Dry Operation condition)
• When the vertical airflow direction is set to Auto using the
remote control, the louver swings up and down as shown in
the diagram.
• When stop operation using the remote control, the
discharge vent is reset, and stop at the closing position.
• During Cooling operation or Soft Dry operation, indoor fan
motor may stop to rotate at certain periods. At that
condition, the louver will stop swinging and rest at the upper
