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 settingtemperature 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 temperatureas 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°CSoft 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 thecircuit 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 operationstop, 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 conditioner is turned on, the compressor will not stop within 60 seconds in a normal operation although the intakeair temperature has reached the thermo-off temperature. However, force stop by pressing the OFF/ON operation button at theremote 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 andreturn back to the outdoor unit.18CS-V18DKE CU-V18DKE / CS-V24DKE CU-V24DKE
