Dry mode (water drop)

The unit takes moisture out of the air with gentle cooling at a low fan speed, trying not to drop the room temperature much.

What pressing it does

For humid, mild weather. Daikin’s DRY “eliminates humidity while maintaining the indoor temperature as much as possible” and only lets you set 0.5–3 °C below the room temperature at the start. Midea and Gree run the fan at low speed and lock it; Panasonic says DRY runs at low fan speed for gentle cooling, with humidity control when the fan is on AUTO.

What it does not do

It is not a humidity setpoint: none of these remotes lets you pick a target humidity, and Samsung says dry mode cannot be used for heating because it is designed to produce a cooling side-effect.

Makes differ, check your unit’s manual: the same drawing can mean different things on different brands, and only your model’s manual says exactly what a button does and which modes it works in.

What it looks like
A single water drop, sometimes with the word DRY. Samsung prints the word Dry.
Names makers use
DRY (Midea, Daikin, Panasonic); Dehumidification (dry) (Airwell); Dry (Samsung)

Where makers differ

The set temperature works differently: Daikin works from the room temperature at start (STD), Airwell and Midea take an ordinary set temperature. Daikin notes that drying is less effective when it is colder outside than inside.

Often confused with

The unit cools the room towards the temperature you set, by moving heat from indoors to the outdoor unit.
