(For 8.5.3. to 8.5.7. information applies only to Cooling and Soft Dry Operation)8.5.3. 7 Minutes Time Save Control• The compressor will start automatically if it has stopped for 7 minutes and the intake air temperature falls between thecompressor ON temperature (A) and compressor OFF temperature (B) during the period.• This phenomenon is to reduce the built up humidity inside a room.8.5.4. 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.8.5.5. Starting Current Control• When the compressor, outdoor fan motor and indoor fan motor are simultaneously started, the indoor fan motor will start tooperate at 1.6 second later.• The reason of the difference is to reduce the starting current flow.8.5.6. 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 exchanger from freezing and to prevent higher volume of refrigerant in liquid formreturning 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.20CS-A18DKD CU-A18DKD / CS-A24DKD CU-A24DKD
