Notes:

• The "Changeover Under Control" icon prevents Cool/Heat mode changes.
• In Heating operation, the fan may continue to run for approximately 1 minute after stopping to remove residual heat.
• Wait at least 5 minutes after stopping operation before turning off the power to allow the drain pump to complete its cycle.

Characteristics of Cooling Operation:

• In Cooling mode with horizontal or downward airflow, the flap may adjust automatically to prevent condensation.
• If the room temperature is low during Cooling operation, frost may form, reducing cooling capacity. The system may automatically enter Defrost operation.
• Cooling may take longer to reach the set temperature when outdoor air temperature is high.

Characteristics of Heating Operation:

• Heating operation may take longer to reach the set temperature compared to cooling. Using the timer for advance operation is recommended.
• The system automatically enters Defrost operation to maintain heating capacity when frost accumulates on the outdoor unit. The indoor unit fan may stop during this period.
• Heating capacity decreases with lower outdoor temperatures. Consider using an auxiliary heating appliance if needed.
• The system warms the entire room through hot air circulation. It may take time for the room to feel warm.
• If warm air collects near the ceiling, a circulator fan may improve comfort.

Dry Operation

1. Preparation: Turn on power at least 6 hours before operation. Dry mode may not be selectable depending on the unit's eligibility.
2. Operation: Press the Mode Selector button until Dry mode is selected.
3. Press the ON/OFF button to start operation. The air conditioner automatically controls temperature and airflow rate; manual adjustments are not available in Dry mode.

Note: Wait at least 5 minutes after stopping operation before turning off the power.

Setting the Cool/Heat Selection Eligibility (VRV only)

This feature allows a designated remote controller to manage Cool/Heat/Auto mode selection for multiple connected units. The controller with eligibility will not display the "Changeover Under Control" icon. Other controllers will display it and follow the selected mode. Vent mode can be set regardless of eligibility. If a "Cool/Heat selector" is used, it overrides remote controller eligibility.

Precautions:

• For Heat Pump Systems with multiple indoor units connected to one outdoor unit, set eligibility on one remote controller for Cool/Heat/Fan modes.
• For Heat Recovery Systems with multiple indoor units connected to one BS unit, set eligibility on one remote controller for Cool/Heat/Auto/Fan modes.
