Cooling Mode Operation

When the intake air temperature reaches 0.5°C(32.9°F) below the setting temp, the compressor and the outdoor fan stop.

When it reaches 0.5°C(32.9°F) above the setting temp, they start to operate again.

Compressor ON Temp

Setting Temp+0.5°C(32.9°F)

Compressor OFF Temp

Setting Temp-0.5°C(31.1°F)

While in compressor running, operating with the airflow speed set by the remote control. While compressor is off fan operates at low speed regardless of the setting.

Soft Dry Operation Mode

When the dehumidification operation input by the remote control is received, the intake air temperature is detected and the setting temp is automatically set according to the intake air temperature.

26°C(78.8°F) Intake Air Temp

25°C(77°F)

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

Intake Air Temp-1°C(30.2°F)

18°C(64.4°F) Intake Intake Air Temp<24°C(75.2°F)

Intake Air Temp-0.5°C(31.1°F)

Intake Air Temp<18°C(64.4°F)

18°C(64.4°F)

While compressor off, the indoor fan repeats low airflow speed and stop.

While the intake air temp is between compressor on temp. and compressor off temp., 10-min dehumidification operation and 4-min compressor off repeat.

Compressor ON Temp. Setting Temp+0.5°C(32.9°F) Compressor OFF Temp. Setting Temp-0.5°C(31.1°F)

In 10-min dehumidification operation, the indoor fan operates with the low airflow speed.

Heating Mode Operation

When the intake air temp reaches +3°(37.4°F)…above the setting temp, the compressor is turned off. When below the setting temp, the compressor is turned on.

Compressor ON Temp. Setting Temp. Compressor OFF Temp. Setting Temp.+3°C(37.4°F)

While compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C(68°F), when above

27°C(80.6°F) , it operates with the low or setting speed. When the indoor pipe temp is between 20°C(68°F) and
