8 Operation Details
8.1. Heating Operation
• Heating operation can be set using remote control.
• This operation is applied to warm 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 heating operation, the compressor will stop running and restart as shown in below figure.
8.1.1. Heating Operation Time Diagram
17
CS-A9DKA CU-A9DKA / CS-A12DKA CU-A12DKA /

8.2. 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.

8.3.1. Soft Dry Operation Time Diagram
8.3. 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.
19
CS-A9DKA CU-A9DKA / CS-A12DKA CU-A12DKA /

8.4. Automatic Operation
• Automatic operation can be set using remote control.
• This operation starts to operate with indoor fan at SLo speed for 25 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.
• Operation mode will be determine again for judgement after 1 hour of operation, if the room temperature reaches to set
temperature and compressor off time is over 7 minutes 30 seconds continuously.
The present operation mode will be continued, if the room temperature does not reach to set temperature (Compressor keeps running)
eventhough after 1 hour from automatic operation mode started.

Automatic Set Temperature
Refer as below.
• Automatic Set Temperature
For each operation, set temperature will automatically set as shown below.
However it can be selected 2°C higher or 2°C lower from standard set temperature by pressing the “Room Temperature Setting
button”.

• 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.
