Changing the Air Flow Rate Setting:

Press the FAN setting button.
In AUTO, HEAT, COOL, or FAN modes, you can select from five levels of air flow rate, indicated by different fan icons, plus an "A" for automatic.
In DRY mode, the air flow rate setting is not variable.
Note that smaller air flow rates result in a smaller cooling effect.

Notes on Operation Modes:

HEAT Mode: Heating capacity decreases in lower outdoor temperatures. If heating is insufficient, supplementary heating may be needed. The heat pump system circulates hot air, so it takes some time for the room to warm up. Frost may form on the outdoor unit in heating operation, triggering a defrosting operation during which hot air will not flow from the indoor unit.
DRY Mode: This mode dehumidifies the indoor air when humidity is high.
AUTO Mode: The system automatically selects a temperature setting and an appropriate mode (COOL or HEAT) based on the room temperature at the start of operation. It periodically reselects settings to maintain the desired temperature. If AUTO mode is not preferred, you can manually select the mode and settings.
