■ 

• 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.

■ 

• When the set time is reached after the on/off time is input by the remote control, the on/off-timer operation is

carried out according to the set time.

■ 

• When the sleep time is reached after <1,2,3,4,5,6,7,0(cancel) hr> is input by the remote control while in appli-

ance operation,  the operation of the appliance stops.

• While the appliance is on pause, the sleep timer mode cannot be input.
• While in cooling mode operation, 30 min later since the start of the sleep timer, the setting temperature

increases by 1°C.  After another 30 min elapse, it increases by 1°C again.

• When the sleep timer mode is input while in cooling cycle mode, the airflow speed of the indoor fan is set to

the low.

• When the sleep timer mode is input while in heating cycle mode, the airflow speed of the indoor fan is set to

the medium.

■ 

• By the Chaos Swing key input, the upper/lower vane automatically operates with the Chaos Swing or they are

fixed to the desired direction.

• While in Chaos Swing mode, the angles of cooling and heating cycle operations are different.

■ 

• When the Chaos Natural Wind mode is selected and then operated, the high, medium, or low speed of the air-

flow mode is operated for 2~15 sec. randomly by the Chaos Simulation.

■ 

• If the Jet Cool key is input at any operation mode while in appliance operation, the Jet Cool mode operates.
• 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 operation, the room temperature is controlled to the setting temperature, 18°C
• When the sleep timer mode is input while in the Jet Cool mode operation, the Jet Cool mode has the priority.
• When the Jet Cool key is input, the upper/lower vanes are reset to those of the initial cooling mode and then

operated in order that the air outflow could reach further.

■ 

• While in heating mode or Fuzzy operation, the Jet Cool key cannot be input.  When it is input while in the other
mode operation (cooling, dehumidification, ventilation), the Jet Cool mode is operated.
• 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 operation, the room temperature is controlled to the setting temperature, 18°C.
• When the sleep timer mode is input while in the Jet Cool mode operation, the Jet Cool mode has the priority.
• When the Jet Cool key is input, the upper/lower vanes are reset to those of the initial cooling mode and then

operated in order that the air outflow could reach further.

■ 

• When the power is restored after a sudden power failure while in appliance operation, the mode before the

power failure is kept on the memory and the appliance automatically operates in the mode on the memory.

• The slide switch on the main unit of the appliance should be on the Auto Restarting position in order that the

Auto Restarting operation is available.

• Operation Mode that is kept on the memory

- State of Operation ON/OFF
- Operation Mode/Setting Temp/Selected Airflow Speed
- Sleep Timer Mode/Remaining Time of Sleep Timer (unit of hour)

■

• 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 position (or test operation) or switched from the remote control posi-
tion 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.

• 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.(only LM-1966C2L/M)

■

• 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 posi-
tion 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 operation

condition is set according to the intake air temperature as follows.

■

• 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.

■

• 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.

■

• 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.
