3. Operating Instructions (GEBRAUCHSANLEITUNG)

Attention

Power on the indoor and outdoor units six hours before operation to protect the compressor. Operate the remote control slowly and steadily.

Guidelines for Room Temperature Settings

• COOL: 26 to 28°C
• DRY: 26 to 28°C
• HEAT: 22 to 24°C
• FAN: Temperature (TEMP) does not need to be set.

Operation

1. Press the ON/OFF button. The green operation indicator light turns on, and operation starts.
2. Press the MODE button to cycle through modes: AUTO, COOL, FAN, DRY, HEAT.
3. Press the TEMP button to adjust the temperature.

6. Press the L/R button (RCN-EK2 only) to adjust horizontal airflow direction.

Notes on Airflow

The movement of the air flap may not match the display; this is not an error. During heating preparation or defrosting, the air flap moves to a horizontal swing mode to prevent direct exposure to cold air. If diffuse airflow is selected, the airflow will be horizontal.

Attention

Do not direct the swing flap downwards for extended periods in cooling mode, as condensation may drip.

9. Press the HI POWER button to start/stop High Power Mode (cooling or heating). This mode quickly brings the room temperature to a comfortable level, operating at accelerated performance for 15 minutes before returning to normal. Note: Using a central control unit may override High Power Mode settings.
10. Press the SILENT button to start/stop Silent Mode Forts., which operates the outdoor unit as quietly as possible.
11. Press the NIGHT SETBACK button to start/stop Away Mode, which prevents significant temperature fluctuations when you are away. Default settings are provided, but can be changed.
