Operation

Forced Operation

To operate the appliance by force in case that the remote control is lost, the forced operation selection switch is on the main unit of the appliance to operate the appliance in the standard conditions.

When the power is supplied while the slide switch is on the forced operation position, or when the slide switch position is switched to the Auto Restarting (or test operation) position or switched from the remote control position to the forced operation position while the power is on, the forced operation is carried out.

When the slide switch position is switched from the forced operation position to the Auto Restarting position or the remote control position, the forced operation is canceled and the appliance stops operating.

In the forced operation mode, the indoor fan is operated at low speed for around 15 sec and then the opera- tion condition is set according to the intake air temperature as follows.

24°C(75.2°F)Intake Air Temp

Cooling Mode Operation, 22°C(71.6°F), High Speed

21°C(69.8°F)Intake Air Temp<24°C(75.2°F)

Dehumidification Operation, 23°C(73.4°F), High Speed

Intake Air Temp<21°C(69.8°F)

Heating Mode Operation, 24°C(75.2°F), High Speed

Buzzer Sounding Operation

When the appliance-operation key is input by the remote control, the short "beep-beep-" sounds.

When the appliance-pause key is input by the remote control, the long "beep—" sounds.
