Operating Mode Symbols

❄️ Cooling Mode (Snowflake)

The snowflake symbol activates cooling mode. This setting lowers the room temperature by producing cool air and is commonly used during Australia’s hot summer months.

☀️ Heating Mode (Sun)

The sun icon represents heating mode. Reverse-cycle air conditioners use this setting to provide warm air during winter, making them a versatile year-round solution.

💧 Dry Mode (Water Droplet)

Dry Mode focuses on removing excess moisture from the air rather than significantly lowering the temperature. It is ideal during humid weather and can make a room feel more comfortable without excessive cooling.

🌀 Fan Mode

Fan Mode circulates air throughout the room without heating or cooling. This setting consumes less energy and is useful when you simply want improved airflow.

🔄 Auto Mode

Auto Mode automatically adjusts temperature and fan speed based on room conditions. This feature helps maintain consistent comfort while optimising energy efficiency.
