11 Operation And Control
11.1. 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.

- Automatic operation 27
- 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 27
- For 11 to 11 information applies only to cooling and soft dry operation 27
- Once the air conditioner 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 27
- Operation control 27
- Restart control time delay safety control 27
- 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 27
- 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 27
- 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 27
- 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 27
