Decoding Mitsubishi Air Conditioners Symbols: Why It Matters
Most Mitsubishi air conditioner remotes pack 20 or more icons onto a surface the size of a chocolate bar. If you have ever pointed one at your unit and genuinely wondered what the little swirling arrows or the blinking snowflake actually do, you are not alone. Understanding mitsubishi air conditioners symbols means the difference between running your system efficiently and accidentally leaving it in the wrong mode all night.
Both Mitsubishi Electric and Mitsubishi Heavy Industries use a largely shared visual language on their remotes, but there are a handful of differences worth knowing. Mitsubishi Electric tends to favour icon-only buttons, while Mitsubishi Heavy Industries remotes occasionally swap icons for text labels on certain functions.
This guide breaks the remote down into four groups: mode icons, fan and airflow icons, timer and sleep icons, and advanced feature icons. Work through each group and the whole remote will make sense.
Key takeaways
- Mitsubishi air conditioners symbols show which mode your unit is running and control fan speed, timers and energy settings.
- The five core modes are Cool, Heat, Dry, Fan Only and Auto, each with a distinct icon on your remote.
- Sleep mode and economy settings help reduce energy bills without sacrificing comfort overnight.
Mode Symbols: Cool, Heat, Dry, Fan, and Auto
The mode symbols on a Mitsubishi remote control which job the unit is doing. There are five core modes across both Mitsubishi Electric and Mitsubishi Heavy Industries models, each represented by a distinct icon. Pressing the 'MODE' button cycles through them in order, so knowing what each icon looks like stops you from accidentally running the heater on a 35-degree Sydney afternoon.
- Cool (snowflake icon): A six-pointed snowflake, usually white or blue. This is the mode that runs the compressor to actively cool the room. It is by far the most-used symbol in Australian summers, and the one most people recognise immediately. Set your target temperature and the unit will cool down to it and hold there.
- Heat (sun icon): A circle with short rays radiating outward, like a simple drawing of the sun. In this mode the refrigeration cycle reverses and the unit pumps warmth into the room. Most Mitsubishi split systems are reverse-cycle, so this mode is just as capable as a dedicated heater.
- Dry (water droplet icon): A single teardrop or water droplet shape. Dry mode runs the unit at low capacity to remove humidity from the air without dramatically dropping the temperature. It is useful on humid coastal days where the air feels sticky but is not actually that hot.
- Fan Only (fan or windmill icon): A stylised multi-blade fan or pinwheel shape. In this mode the compressor is off entirely and the unit simply circulates air around the room. No cooling, no heating, no dehumidifying. It uses very little electricity and is handy for moving air on mild evenings.
- Auto (circular arrows or 'A' icon): Either two curved arrows forming a loop, or simply the letter 'A' inside a circle. Auto mode lets the unit decide whether to cool or heat based on the room temperature versus your set point. Mitsubishi Heavy Industries remotes sometimes skip the icon altogether and print 'AUTO' in text instead, so do not be surprised if yours looks different.
One thing worth noting: Dry mode is not a substitute for a dedicated dehumidifier in very humid climates like Far North Queensland. It works well for mild humidity but will struggle to keep up in a room that is genuinely saturated with moisture.
For a broader look at how these same icons appear across other brands, the air conditioner symbols explained guide covers the full picture in a brand-agnostic format.
Fan Speed and Airflow Symbols on Your Mitsubishi Remote
The fan speed and airflow symbols on a Mitsubishi remote control how hard the unit blows and where that air goes. Fan speed is usually shown as a series of vertical bars or horizontal lines, with more bars meaning more airflow. Getting these settings right makes a bigger difference to comfort than most people realise, especially in larger rooms or open-plan spaces.
Fan Speed
Most Mitsubishi remotes offer four fan speed settings. Low is one bar or a short line, Medium is two bars, High is three bars, and Auto lets the unit choose the speed based on how far the room temperature is from your set point. Some models also include a 'QUIET' or 'SILENT' setting, shown as a crescent moon paired with a small fan icon. This mode caps the fan at its lowest possible speed to reduce noise, making it ideal for bedrooms overnight. The trade-off is slower cooling or heating, so it works best once the room is already close to your target temperature.
Vertical Swing
The vertical swing symbol is an up-and-down arrow, or a series of curved horizontal lines suggesting a louvre moving through an arc. Activating this makes the horizontal louvre oscillate continuously from near-horizontal to near-vertical, distributing air across the full height of the room. You can also press the button once to stop the louvre at a fixed angle if you prefer airflow directed at a specific spot.
Horizontal Swing
The horizontal swing symbol looks like a left-right arrow or a fan shape spreading sideways. This moves the vertical louvres side to side, spreading airflow across the width of the room rather than just straight ahead. Not all Mitsubishi models include motorised horizontal swing, so check your unit's spec sheet if you cannot find this button.
3D Auto Airflow
On select Mitsubishi Electric AP-series models, you may see a globe icon or a multi-directional arrow symbol labelled '3D AUTO'. This combines both vertical and horizontal swing simultaneously, letting the unit distribute air in all directions automatically. It is particularly useful in square rooms where a single airflow direction would leave corners feeling stuffy.
Timer, Sleep, and Economy Symbols
The timer, sleep and economy symbols on a Mitsubishi remote handle scheduling and energy management. These are the icons most people ignore, yet they are some of the most useful for cutting electricity bills and getting a comfortable night's sleep. Once you know what each one does, setting them takes less than a minute.
On Timer
The On Timer symbol is a clock face with an arrow pointing to the right, or the word 'ON' printed next to a clock. It schedules the unit to start at a time you choose. For Australian households, this is handy for pre-cooling a bedroom before you go to sleep, or warming up a living room before you get out of bed on a cold winter morning. You set the delay in 10-minute or 30-minute increments depending on the model.
Off Timer
The Off Timer symbol mirrors the On Timer but with the arrow pointing left, or 'OFF' next to the clock face. It tells the unit to shut down after a set period. Running the air conditioner for two hours after you fall asleep and then letting it switch off automatically is a practical way to save energy without sacrificing comfort at bedtime.
Sleep Mode
The sleep mode symbol is a crescent moon, sometimes with a small 'Z' or a star beside it. This is different from simply using the Off Timer. Sleep mode gradually shifts the set temperature by one or two degrees over a few hours, reducing energy use and fan noise as the night progresses. Mitsubishi Electric models typically raise the set temperature slightly in Cool mode and lower it slightly in Heat mode, following the natural drop in body temperature during sleep.
Economy and Econo Cool
The economy symbol varies between the two brands. Mitsubishi Heavy Industries remotes use a small leaf icon to indicate Economy mode, which caps the compressor's maximum power draw to reduce running costs. Mitsubishi Electric remotes instead use the text label 'ECONO COOL', which works similarly by limiting peak power consumption. Neither mode is as aggressive as simply raising your set temperature, but both take the edge off your electricity bill during long running periods. For a household running the air conditioner six or more hours a day through a Queensland summer, that adds up.
Other brands use comparable icons for these functions with slightly different visual styles. The Daikin air con remote symbols explained guide is a useful comparison if you have a mix of brands in your home or are trying to decode a remote from a different manufacturer.
Advanced and Brand-Specific Mitsubishi Remote Symbols
Beyond the everyday mode and fan icons, Mitsubishi Electric and Mitsubishi Heavy Industries remotes each carry a handful of brand-specific symbols that most owners never fully decode. These icons cover energy personalisation, air purification, app connectivity and service alerts. Knowing what they mean saves you from ignoring a useful feature or panicking over a light that is simply asking for a filter clean.
i-Save (Mitsubishi Electric)
The i-Save symbol appears as a small calendar grid or a stylised 'i' icon on Mitsubishi Electric remotes. It stores your preferred temperature setting so you can return to it with a single button press, rather than adjusting the temperature from scratch each time. Think of it as a personal preset. The Mitsubishi Electric split systems in the AP-series, including the Mitsubishi Electric 2.5kW Split System MSZAP25VGKD ($1,035) and the 5kW MSZAP50VGKD ($1,686), both feature this function alongside the 3D Auto Airflow symbol covered in the previous section.
Plasma / Nano Platinum Filter Indicator (Mitsubishi Heavy Industries)
On select Mitsubishi Heavy Industries models, a small diamond shape or the letter 'P' indicates that the Plasma or Nano Platinum filter is active. This is an air purification feature built into the indoor unit, and the icon simply confirms it is running. If the icon flashes or disappears, it usually means the filter needs cleaning rather than replacing.
Wi-Fi / Wireless Connectivity Icon
The Wi-Fi symbol, a series of curved arcs like an upside-down teardrop, confirms the unit is connected to its companion app. Mitsubishi Electric models connect via MELCloud, while Mitsubishi Heavy Industries models use the MHI Comfort Cloud app. The Mitsubishi Heavy Industries Avanti Plus 6kW Split System SRK60ZSXA-WF ($2,254) has built-in Wi-Fi and displays this icon on its remote when the connection is live. Both apps let you control the unit remotely from your phone, set schedules and monitor energy use.
Check / Service Light
A spanner icon or an exclamation mark inside a triangle is the service or check light. This symbol is easy to misread as a serious fault, but it most commonly appears as a routine filter clean reminder after a set number of operating hours. Check your filter first. If the light persists after cleaning and resetting, consult the fault code in your owner's manual before calling a technician, as many codes point to minor issues like a blocked drain or a brief sensor reading rather than a compressor problem.
| Symbol | Icon appearance | Brand | What it does |
|---|---|---|---|
| i-Save | Calendar grid or 'i' icon | Mitsubishi Electric | Recalls your stored preferred temperature setting |
| Plasma / Nano Platinum | Diamond or 'P' icon | Mitsubishi Heavy Industries | Confirms air purification filter is active |
| Wi-Fi / Wireless | Curved arc (Wi-Fi) symbol | Both brands | Shows app connectivity (MELCloud or Comfort Cloud) |
| Check / Service | Spanner or exclamation mark | Both brands | Filter clean reminder or fault code alert |
Frequently Asked Questions
What does the snowflake symbol mean on a Mitsubishi remote?
The snowflake symbol on a Mitsubishi remote indicates Cool mode. In this mode the unit runs its compressor to actively lower the room temperature to your chosen set point. It is the most commonly used mode in Australian summers and is available on all Mitsubishi Electric and Mitsubishi Heavy Industries reverse-cycle split systems.
What is the 3D Auto symbol on a Mitsubishi Electric remote?
The 3D Auto symbol, shown as a globe or multi-directional arrow icon, activates simultaneous vertical and horizontal louvre swing. This distributes conditioned air in all directions automatically, rather than in a single fixed direction. It is found on AP-series Mitsubishi Electric models and works best in square or open-plan rooms where a single airflow direction would leave parts of the space uncovered.
Why is there a flashing light on my Mitsubishi air conditioner remote?
A flashing light on a Mitsubishi remote or indoor unit most often signals a filter clean reminder, which triggers automatically after a set number of operating hours. Clean the filter, then hold the reset button (usually labelled 'FILTER' or shown as a small broom icon) for three seconds to clear the alert. If the light continues flashing after a reset, check the fault code in your owner's manual, as it may point to a sensor or drainage issue that needs attention.
What is the difference between Mitsubishi Electric and Mitsubishi Heavy Industries remotes?
Mitsubishi Electric and Mitsubishi Heavy Industries are separate companies with their own product lines and remotes, despite sharing a similar name. Mitsubishi Electric remotes tend to use icon-only buttons and include brand-specific features like i-Save and MELCloud Wi-Fi connectivity. Mitsubishi Heavy Industries remotes occasionally use text labels in place of icons and carry their own features such as the Nano Platinum filter indicator and Comfort Cloud app integration. The two remotes are not interchangeable between brands.
