You’ve just purchased a new split system and the remote control has 20 buttons – and you only use three of them. Sound familiar? You’re not alone. Most Melbourne homes just hit the Power, Temperature Up and Temperature Down buttons and don’t use anything else.
This comprehensive guide breaks down all the symbols on an air conditioning unit – unlocking the full potential of your equipment, saving on energy bills and being comfortable all year round. Whether you have a Daikin, Mitsubishi, Panasonic, LG or any other brand, the symbols are basically universal.
Why Understanding AC Symbols Matters
Air conditioners are very complicated pieces of equipment these days. Your remote settings and modes are designed to put you in exact control of efficiency and comfort. Using the wrong mode incorrectly – such as leaving a unit on Cool mode on a cold Melbourne night costs electricity and lowers comfort.
Understanding the meaning of your AC remote symbols will help you utilise the proper mode at the right time and this can cut your energy consumption by up to 30 percent according to energy efficiency studies.
Every Air Conditioning Symbol Explained
The table below covers all major AC remote icons you will find on virtually every brand sold in Australia, including their meaning and what they actually do:
| Symbol / Button | Meaning | What It Does |
| Power | On / Off toggle | Turns the unit on or off; retains last settings |
| Mode | Operating mode selector | Cycles: Cool, Heat, Fan, Dry, Auto |
| Sun (Heating) | Heat mode | Warms the room — ideal for Melbourne winters |
| Snowflake (Cool) | Cooling mode | Lowers room temperature — essential in summer |
| Water Droplet | Dry / Dehumidify mode | Removes humidity without significant cooling |
| Fan / Arrows | Fan-only mode | Circulates air with no heating or cooling |
| Fan Speed (1-4) | Airflow strength | Low / Med / High / Turbo — higher = faster cool |
| Sleep | Sleep / Night mode | Gradually adjusts temp for comfortable sleep |
| Timer | Scheduled on/off | Set the AC to start or stop at a chosen time |
| Swing / Louvre | Airflow direction | Auto-swings vanes to distribute air evenly |
| Turbo / Boost | Maximum power mode | Reaches target temp as fast as possible |
| Eco / Leaf | Energy-saver mode | Reduces power use — lowers electricity bills |
| Lock | Child lock / Remote lock | Prevents accidental setting changes |
Key AC Mode Symbols — Explained in Detail
Cool Mode (Snowflake)
The snowflake is the most-used symbol on Australian AC remotes. It activates the primary cooling function, where the system extracts heat from indoor air and expels it outside. Set your temperature between 23 and 26 degrees Celsius for optimal efficiency during Melbourne summers.
Heat Mode (Sun)
The sun symbol activates reverse-cycle heating. The system draws heat energy from outside air — even in cold weather — and transfers it indoors. This is the most energy-efficient way to heat your home, far cheaper than gas or resistive electric heating. Perfect for Melbourne winters.
Dry Mode (Water Droplet)
Dry mode reduces indoor humidity without aggressively cooling the room. The fan runs at a lower speed and the compressor cycles on and off. It is ideal for Melbourne’s muggy late-summer days when the air feels sticky but the temperature is not excessively hot.
Fan Mode (Fan Blades / Arrows)
Fan mode circulates air using the indoor blower without activating the compressor. No cooling or heating occurs. This is useful for ventilation on mild days and is the lowest-cost mode to run.
Auto Mode (A or Circle with Arrows)
Auto mode lets the unit decide whether to heat or cool based on the gap between the current room temperature and your target setting. It is a hands-off, convenient option for Melbourne’s unpredictable spring and autumn weather.
Fan Speed, Swing, and Special Function Symbols
Fan Speed (1, 2, 3, Auto, Turbo)
Fan speed controls how fast air is pushed through the system. Low speed is quieter and suits bedrooms. High speed or Turbo cools or heats a room fast on extreme days. Auto fan speed lets the unit adjust based on how far the room temperature is from the set point.
Swing / Louvre
The swing symbol (usually illustrated as a fan with arrows) controls the direction of the airflow louvres. Activating this causes the vents to automatically move up and down, distributing conditioned air evenly across the room rather than in one direction only.
Sleep Mode (Moon)
Sleep mode gradually increases the set temperature by one degree per hour after you fall asleep, saving energy through the night without making you uncomfortable. A highly underused feature that can noticeably reduce overnight running costs.
Eco / Energy Saver
The Eco or leaf symbol activates an energy-saving algorithm. The compressor and fan operate at reduced capacity once the target temperature is reached, rather than cycling on at full power. Ideal for everyday use when comfort, not speed, is the priority.
Do All Brands Use the Same AC Symbols?
The short answer is yes mostly. While the physical appearance of each icon varies between Daikin, Mitsubishi Electric, Panasonic, LG, and Samsung, the underlying symbols and their meanings are standardised across the air conditioning industry in Australia.
The main exceptions are brand-specific smart features such as Daikin’s Intelligent Eye, Mitsubishi’s Weekly Timer, or Panasonic’s nanoe-X air purification mode. These are labelled differently and described in your product manual. If you have lost your manual, ND Cooling Solutions can help — our technicians are trained across all major brands.

Frequently Asked Questions
| What does the snowflake symbol mean on an AC remote? |
| A: The snowflake symbol represents Cool mode. When selected, your air conditioner activates its compressor to extract heat from your indoor air and release it outside, lowering the room temperature. It is the standard mode to use on hot days in Melbourne. |
| What is the difference between Dry mode and Cool mode on an AC? |
| A: Cool mode actively lowers the room temperature by running the compressor at full capacity. Dry mode targets humidity reduction rather than temperature drop — the compressor runs intermittently at a lower fan speed. Dry mode is ideal for humid days when the temperature is mild but the air feels uncomfortable. |
| What does the fan symbol on my AC remote mean? |
| A: The fan symbol activates Fan-only mode. In this mode, the air conditioner’s blower circulates air around the room without activating the compressor for heating or cooling. It is the most energy-efficient mode and is useful for ventilating a room on mild days. |
| Why should I use Sleep mode on my air conditioner? |
| A: Sleep mode gradually adjusts the set temperature upward (by one degree per hour) after activation, allowing you to fall asleep comfortably while the system reduces its energy consumption through the night. It is one of the most effective ways to cut overnight running costs without sacrificing sleep comfort. |
