Forced Operation (H/P Model)

• 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.

• The forced operation is carried out in cooling mode with the setting temperature 22°C and the high speed of

airflow.

• 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

≤

Intake Air Temp

➲

Cooling Mode Operation, 22°C, High Speed

21°C

≤

Intake Air Temp<24°C

➲

Dehumidification Operation, 23°C, High Speed

Intake Air Temp<21°C

➲

Heating Mode Operation, 24°C, High Speed

• While in forced operation, the key input by the remote control has no effect and the buzzer sounds 10 times to

indicate the forced operation.

■

Remote Control Operation Mode

• When the remote control is selected by the slide switch on the main unit, the appliance operates according to

the input by the remote control.

■

Protection of the evaporator pipe from frosting

• If the indoor pipe temp is below 0°C in 7 min. after the compressor operates without any pause while in cool-

ing cycle operation mode, the compressor and the outdoor fan are turned off in order to protect the indoor
evaporator pipe from frosting.

• When the indoor pipe temp is 7°C or higher after 3 min. pause of the compressor, the compressor and the

outdoor fan is turned on according to the condition of the room temperature.

■

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.
• When a key is input by the remote control while the slide switch on the main unit of the appliance is on the

forced operation position, the error sound "beep-beep-beep-beep-beep-" is made 10 times to indicate that the
remote control signal cannot be received.
