Operation

2)Fuzzy Operation for Dehumidification

• According to the set point temperature selected by Fuzzy rule, when the intake air temp is 0.5°C(0.9°F) or

more below the set point temp, the compressor is turned off. When 0.5°C(0.9°F) or more above the set point temp, the compressor is turned on.

Compressor ON Temp

➲ Set point Temp + 0.5°C(0.9°F)

Compressor OFF Temp

➲ Set point Temp+0.5°C(0.9°F)

•At the beginning of Fuzzy mode operation, the set point temperature is automatically selected according to the intake air temp at that time.

26°C(78.8°F) ≤ Intake Air Temp

➲ 25°C(77°F)

24°C(75.2°F) ≤ Intake Air Temp<26°C(78.8°F)

➲ Intake Air Temp+1°C(1.8°F)

22°C(71.6°F) ≤ Intake Air Temp<24°C(75.2°F)

➲ Intake Air Temp+0.5°C(0.9°F)

18°C(64.4°F) ≤ Intake Air Temp<22°C(71.6°F)

➲ Intake Air Temp

Intake Air Temp<18°C(64.4°F)

➲ 18°C(64.4°F)

•When the Fuzzy key (Temperature Control key) is input after the initial set point temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the set point temperature automatically according to the Fuzzy rule.

•While in Fuzzy operation, the airflow speed of the indoor fan repeats the low airflow speed or , except in dehu- midification mode where the indoor fan may pause.

3)Fuzzy Operation for Heating

•According to the set point temperature selected by Fuzzy rule, when the intake air temp is 3°C(37.4°F) or more above the set point temp, the compressor is turned off. When below the set point temp, the compressor is turned on.

Compressor ON Temp

➲ Set point Temp

Compressor OFF Temp

➲ Set point Temp + 3°C(5.4°F)

•At the beginning of Fuzzy mode operation, the set point temperature is automatically selected according to the intake air temp at that time.

20°C(68°F)≤Intake Air Temp

➲ Intake Air Temp + 0.5°C(0.9°F)

Intake Air Temp<20°C(68°F)

➲ 20°C(68°F)

•When the Fuzzy key (Temperature Control key) is input after the initial set point temperature is selected, the Fuzzy key value and the intake air temperature at that time are compared to select the set point temperature automatically according to the Fuzzy rule.

•While in Fuzzy operation, the airflow speed of the indoor fan is set to the high or medium according to the intake air temperature and the set point temperature.

■Airflow Speed Selection

•The airflow speed of the indoor fan is set to high, medium, low, or power (auto) by the input of the airflow speed selection key on the remote control.

■On-Timer Operation

•When the set time is reached after the time is input by the remote control, the appliance starts to operate.

•The timer LED is on when the on-timer is input. It is off when the time set by the timer is reached.

•If the appliance is operating at the time set by the timer, the operation continues.

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

■Off-Timer Operation

•When the set time is reached after the time is input by the remote control, the appliance stops operating.

•The timer LED is on when the off-timer is input. It is off when the time set by the timer is reached.
