Operation
2) Fuzzy Operation for Dehumidification
• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 0.5°C or more below
the setting temp, the compressor is turned off. When 0.5°C or more above the setting temp, the compressor
is turned on.

➲
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.

• 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.
3) Fuzzy Operation for Heating
• According to the setting temperature selected by Fuzzy rule, when the intake air temp is 3°C or more above
the setting temp, the compressor is turned off. When below the setting temp, the compressor is turned on.

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 set to the high or the medium according to the
intake air temperature and the setting 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.

■
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.
• If the appliance is on pause at the time set by the timer, the pause continues.
