Operation

■Airflow Speed Selection

•The airflow speed of the indoor fan is set to high, medium, low, or chaos (auto) by the input of the airflow speed selection key on the remote control.

■Sleep Timer Operation

•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 appliance 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 tempera- ture 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.

■Chaos Natural Wind Mode

•When the Chaos Natural Wind mode is selected and then operated, the high, medium, or low speed of the airflow mode is operated for 2~15 sec. randomly by the Chaos Simulation.

■Jet Cool Mode Operation (C/O Model)

•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.

■Jet Cool Mode Operation (H/P Model)

•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.
