Air Conditioner Remote Symbols Explained: Cool, Fan, Auto and More

Start with the mode, not the temperature

Air conditioner remote symbols usually identify the operating mode, fan setting, airflow direction or timer. They are not completely standardised, so your model's manual is the final reference.

If the room isn't cooling as expected, check the mode before repeatedly lowering the temperature. A low temperature displayed alongside fan-only mode will not make the system actively cool.

Snowflake: cooling mode

A snowflake commonly represents cooling. In this mode, the system aims to cool towards the selected temperature, within its operating capabilities. It may reduce output or pause when the target is reached.

Do not confuse the target temperature on the remote with the room's current measured temperature. Some models show one, some the other, and some let you switch the display.

Sun: heating mode

A sun commonly indicates heating on reverse-cycle systems. Not every air conditioner supports heating, even if a universal remote has a heat button or symbol.

If a replacement remote offers a function the unit does not support, selecting it will not add that feature to the appliance.

Fan and auto: two different questions

A fan symbol can indicate fan-only operation or fan-speed selection, depending on where it appears. Fan-only circulates air without active cooling or heating.

Auto can also mean different things. Auto operating mode may let the system choose its operation, while auto fan adjusts fan speed. Check whether you are changing the operating mode or only the fan setting.

Swing, timer and lock symbols

Swing usually controls a moving airflow louvre. Some units offer separate vertical and horizontal controls; others support only one direction.

A clock commonly relates to a timer, but it might represent the current clock, a delayed start or a scheduled stop. A padlock can indicate locked remote buttons. Use your model's instructions rather than guessing a button combination.

Droplet, moon and leaf symbols

A droplet often indicates dry mode, a moon may indicate sleep mode, and a leaf may relate to an economy setting. Their behaviour varies by model. These modes are not interchangeable, and no symbol guarantees a particular reduction in electricity use.

Frequently asked questions

Why does my remote show symbols my air conditioner doesn't support?

Some remotes are designed for multiple models. Check which functions your indoor unit supports.

Will a replacement remote use the same symbols?

Not always. Match compatibility and required functions first, then check the replacement's instructions. Keep your indoor unit's model number handy when comparing options at Office Catch.
