What do pictorial settings mean on an air conditioner?

Pictorial settings on an air conditioner refer to the visual icons or images displayed on the unit or its remote control, representing various modes and functions. These may include symbols for cooling, heating, fan, dehumidification, or specific temperature settings. Such visual cues help users easily understand and select the desired operation mode without needing to read text instructions. This design enhances usability, especially for individuals who may not be familiar with technical terminology.
