Operation Details

1) Fuzzy Operation for Cooling

• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C(33°F) or more

below the setting temp, the compressor is turned off. When 0.5°C(33°F) or more above the setting temp, the

compressor is turned on.

Compressor ON Temp. => Setting Temp+0.5°C(33°F)

Compressor OFF Temp. => Setting Temp+0.5°C(33°F)

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

intake air temp at that time.

26°C(78°F) ≤ Intake Air Temp => 25°C(76°F)

24°C(76°F) ≤ Intake Air Temp < 26°C(78°F) => Intake Air Temp+1°C(34°F)

22°C(72°F) ≤ Intake Air Temp<24°C(76°F) => Intake Air Temp+0.5°C(33°F)

18°C(64°F) ≤ Intake Air Temp<22°C(72°F) => Intake Air Temp

Intake Air Temp<18°C(64°F) => 18°C(64°F)

• 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 according to the Fuzzy rule.

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

2) Fuzzy Operation for Dehumidification

• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C(33°F) or more

below the setting temp, the compressor is turned off. When 0.5°C(33°F) or more above the setting temp, the

compressor is turned on.

Compressor ON Temp. => Setting Temp+0.5°C(33°F)

Compressor OFF Temp. => Setting Temp+0.5°C(33°F)

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

intake air temp at that time.

26°C(78°F) ≤ Intake Air Temp => 25°C(76°F)

24°C(76°F) ≤ Intake Air Temp < 26°C(78°F)=> Intake Air Temp+1°C(34°F)

22°C(72°F) ≤ Intake Air Temp<24°C(76°F) => Intake Air Temp+0.5°C(33°F)

18°C(64°F) ≤ Intake Air Temp<22°C(72°F) => Intake Air Temp

Intake Air Temp < 18°C(64°F) => 18°C(64°F)

• 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 according to the Fuzzy rule.

• While in Fuzzy operation, the airflow speed of the indoor fan repeats the low airflow speed or pause as in

dehumidification operation.
