Part 2 Functions & Controls

3. Special Mode Controls

3.1 Jet Cool operation

• In the heating mode or Auto Changeover operation, the Jet cool function does not work.

When it is input while in other mode of operation (cooling, dehumidification, Air purification, Air circulation), the Jet cool operation takes place.

• In the Jet cool mode, the indoor fan is operated at super-high speed for 30 min. at cooling mode operation.

• In the Jet cool mode, the room temperature is maintained at a setting temperature of 18°C(64.4°F).

• When the sleep timer mode is input during the Jet cool operation, the Jet cool mode has the priority.

• When the Jet cool button is pressed, the horizontal vane of the unit is reset to those of the initial cooling mode and then operate so that the air outflow could reach further.

3.2 Jet Heat operation

• While in cooling mode or Auto Changeover operation, the Jet Heat function does not work.

When it is input while in the Heating mode operation (dehumidification), the Jet Heat mode operation takes place

• In the Jet Heat mode, the indoor fan operated at super-high speed for 60 min. at Heating mode operation.

• In the Jet Heat mode, the room temperature is maintained at a temperature of 30°C(86°F).

• When the sleep timer mode is input during the Jet Heat mode operation, the Jet Heat mode has the priority.

• When the Jet Heat button is pressed, the horizontal vane of the unit is the unit reset to those of the initial Jet heating mode and then operates so that the air outflow could reach under flow.

3.3 Energy saving operation in cooling mode

• During cooling and dehumidification mode of operation, the Energy saving button can be input.

• In this operation, before we feel cold the set temperature and air volume is set automatically to save energy.
