6.3 Auto Operation (Artificial Intelligence)

• When any of operation mode is not selected like the moment of the power on or when 3 hrs has passed since the op-

eration off, the operation mode is selected.

• When determining the operation mode, the compressor, the outdoor fan, and the 4 way valve are off and only the in-

door fan is operated for 15 seconds. Then an operation mode is selected according to the intake air temp at that mo-

ment as follows.

24°C ≤ Inatake Air Temp ‘ Fuzzy Operation for Cooling

21°C ≤ Inatake Air Temp < 24°C ‘ Fuzzy Operation for Dehumidification

Inatake Air Temp < 21°C ‘ Fuzzy Operation for Heating

• If any of the operation modes among cooling / dehumidification / heating mode operations is carried out for 10 sec or

longer before Fuzzy operation, the mode before Fuzzy operation is operated.

6.3.1 Fuzzy Operation for Cooling

• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below the set-

ting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor is turned on.

Compressor ON Temp ‘ Setting Temp + 0.5°C

Compressor OFF Temp ‘ Setting Temp + 0.5°C

• At the beginning of Fuzzy mode operation, the setting temperature is automatically selected according to the intake air

temp at that time.

26°C≤ Intake Air Temp ‘ 25°C

24°C≤ Intake Air Temp<26°C ‘ Intake Air Temp + 1°C

22°C≤ Intake Air Temp<24°C ‘ Intake Air Temp + 0.5°C

18°C≤ Intake Air Temp<22°C ‘ Intake Air Temp

Intake Air Temp<18°C ‘ 18°C

• When the Fuzzy key (Temperature Control key) is input after the initial setting temperature is selected, the Fuzzy key

value and the intake air temperature at that time are compared to select the setting temperature automatically accord-

ing to the Fuzzy rule.

• While in Fuzzy operation, the airflow speed of the indoor fan is automatically selected according to the temperature.

6.2 Auto cleaning operation

• Function used to perform Self Cleaning to prevent the Unit from Fungus and bad odor.

• Used after the Cooling Operation before turning the unit off, clean the Evaporator and keep it dry for the next opera-

tion.

• The function is easy to operate as it is accessed through the Remote controller.
