When it’s over 30 degrees outside and almost as sweltering inside, you probably want some instant cooling relief, not to scratch your head and stare at buttons on an air con remote. Some symbols may make sense at a glance, but others can be puzzling, and some can even mean there’s a problem with your unit. So, how do you know which is which?
As experienced air conditioning technicians, we know that understanding how an AC works can make all the difference in helping it run efficiently and keeping your power costs down. This can be as simple as running your system on the optimal mode for air conditioning in Sydney, and the first step is identifying the right symbols for that setting.
In this guide, we’ll cover the most common Daikin aircon symbol meanings, when each mode is most suitable, and what to look out for if you want to keep your system running well for years to come.
What Are Daikin Air Conditioning Symbols?
Simply put, the symbols on Daikin air conditioners are there to show you the current operating mode, airflow settings, fan controls, and energy-saving features of your air conditioning unit.
They’re visual shortcuts designed to help you manage your indoor climate, so you can find the right balance between your comfort and personal preferences, energy efficiency and household costs, and the demands of the Australian climate.
Most Daikin air con symbols are universal (or standard) across models and other major air conditioner brands, so you shouldn’t have a steep learning curve if you ever upgrade or replace your home unit.
Understanding the Basics of Daikin Operating Mode Symbols
The most important Daikin remote control symbols are the five operating mode symbols.
These indicate what your unit is actually doing to your home’s interior climate. They’re what help you find the right settings for a cool home in the summer, or a warm sanctuary in the colder months, without sending your power bill through the roof.
For your reference, the five core operating symbols on a Daikin air con remote are Auto, Cool, Heat, Fan Only, and Dry:
| Symbol (Icon) | Operating Mode | Function | Best For |
| 🔁
“A” with four arrows framing clockwise |
Auto | Auto mode lets your AC unit decide the right settings based on your set desired temperature | Transitional seasons (spring and autumn), when temperatures are likely to change throughout the day |
| ❄️
Snowflake |
Cool | Cool mode lowers room temperature by actively removing heat from the air | Uncomfortably hot days (or nights) when you need fast and reliable cooling relief |
| ☀️
Sun |
Heat | Heat mode uses reverse cycle heating to raise room temperatures | Cold days or chilly mornings when temperatures drop uncomfortably low |
| 🌀
Fan blades |
Fan Only | Fan Only mode circulates air without adjusting the temperature of a room | When indoor temperatures are comfortable but you want airflow to move stale or stuffy air |
| 💧
Two water droplets in a box |
Dry | Dry mode reduces the humidity level in a room without major temperature changes | When temperatures are mild, but the air indoors feels heavy, sticky, or humid |
Fan Speed and Airflow Symbols Explained
The fan speed and airflow symbols on your Daikin air con remote are what determine the strength your unit blows air with, and where that air is supposed to go.
If you’re sitting in one corner of a hot room and your air con is blowing cool air in the opposite direction, you won’t be enjoying optimal conditions, but having the right fan and airflow settings can help.
Symbols to Adjust Fan Speed
The fan speed (also known as airflow rate or airflow level) options on your remote are most commonly displayed as a series of horizontal lines or vertical bars, and grow progressively bigger as speed increases.
Most Daikin air conditioners have four speed settings: Auto, High, Medium, and Low.
If you’re trying to cool or heat a room quickly, then you’ll want to set your fan speed to high. However, keep in mind that higher settings will use more power and be more expensive to run.
For basis day-to-day comfort and efficiency, it’s recommended that you set your systems to “Auto”, and allow your Daikin unit to manage its own speed based on your preferred temperature settings.
Managing Airflow with Swing and Louvre Symbols
The swing symbol on your Daikin air conditioner’s remote is most likely a curved arrow, or a single up-and-down arrow next to a set of louvres (the angled blades controlling your airflow).
When you enable the swing function, the horizontal louvres will move up and down continuously to distribute air across the whole room for even temperature distribution.
Some models will let you lock the louvres in a fixed position for better control over your indoor climate. For example:
- An upward tilt (or straight horizontal angle) in Cool mode means the cold air will fall and spread evenly across the room
- A downward tilt in Heat mode means that warm air will actually reach where you are (as hot air rises)
Select Daikin units also have a symbol to control horizontal swing, and this is usually displayed as a left-to-right arrow. It can also be set for continuous oscillation, or locked, and gives you full control over which corner of the room the air will reach.
Special Feature Symbols on Daikin Remotes
While there are five core operating mode symbols on most Daikin remotes, many mid- to premium-range models have a series of special function symbols.
These advanced modes add an extra layer of personalisation to your air conditioning system, from rapid cooling after a sweltering day outside to scheduling your heating to come on 10 minutes before you walk in the door.
The most commonly used special Daikin air conditioner remote control symbols include:
| Symbol (Icon) | Advanced Mode | Function | Best For |
| 💪
Person flexing |
Powerful | Powerful mode temporarily runs at full capacity (~20 minutes) to rapidly cool or heat a room | When you need to cool or heat a room as quickly as possible |
| 🌙
Moon and stars |
Sleep | Sleep mode gradually adjusts the set temperature over a few hours and reduces fan noise | Nights when the temperature is too hot or too cold for a comfortable sleep |
| ⬇️
Downward arrow with a line below |
Econo | Econo mode limits the AC’s maximum power draw | When you’re running other high-draw household appliances (like ovens, washing machines, or dryers) |
| 🌲
Tree and moon |
Quiet | Quiet mode reduces the noise of an indoor unit’s fan speed | When you want to maintain an already comfortable room temp with less noise |
| 🕓
Clock with “ON” or “OFF” |
Timer | Timer mode lets you schedule a time each day for the unit to turn on or off | When you know what time you’ll arrive home each day and want a room to be ready for you (some models even support weekly schedules) |
Daikin Aircon Symbols Explained by Model
It’s important to note that some Daikin air conditioning systems won’t have all five modes available.
This is most common across entry-level and cooling-only AC units, where “Dry” mode may not be an option, “Auto” and “Fan” are often combined, and many advanced features (like weekly timers) are omitted.
If the symbols on your remote are not what you expect, we recommend checking your operating manual to see what’s included for your specific Daikin model.
What You Need to Know About Daikin Warning and Fault Symbols
Most warning symbols and maintenance alerts on your Daikin aircon remote or wall display are not an immediate cause for alarm.
They’re designed to let you know when something is preventing your unit from working to its full potential, or simply that it’s time to clean your AC’s filters.
However, there can also be cases where these alerts mean there is a serious fault with the unit, and you will have to call a professional for air conditioning maintenance and support.
Understanding these fault and maintenance symbols can help you determine the best steps to protect your unit in the long run, and we’ve broken down some of the most common warning alerts for you:
| Symbol (Icon) | Alert Type | Purpose | Prompt |
| 🔳
Small square grid |
Maintenance | To notify you when the filter is due for a routine clean (after ~250 hours of use) | Clean or replace your AC’s dirty filter to maintain efficiency |
| 🔧
Spanner (flashing or accompanied by an error code) |
Fault | To notify you when the AC unit has detected a technical system fault | Retrieve the fault code and contact a licensed air conditioning technician |
| 🟢
Blinking operation lamp |
Fault | To let you know there is an abnormality with the unit | Retrieve the fault code and contact a licensed air conditioning technician |
Retrieving a Fault Code From Your Daikin Remote
If your Daikin air conditioning remote is alerting you to a fault and you’re looking for a solution, you’ll first need to find the specific fault (or error) code.
On a standard Daikin wireless remote, you can retrieve this code by:
- Holding the “CANCEL” button until you see a flashing “00” on the screen (this may take around 5 seconds)
- Repeatedly pressing the “CANCEL” button to cycle through error codes (this will prompt the unit to emit beeps)
- Listening to the beeps (short beeps or two consecutive beeps mean an incorrect code, while a long continuous beep indicates the correct active fault code)
- Taking note of the on-screen code (this should look like a letter and a number, e.g. U4 for communication issues or A6 for an overloaded fan)
