Decoding Mitsubishi Air Conditioner Symbols: Why It Matters
You pull out your Mitsubishi remote, squint at a row of tiny icons, and guess. Most people do. But misreading those Mitsubishi air conditioner symbols can mean running your unit in the wrong mode for hours, wasting electricity and never quite hitting the comfort level you're after. Getting familiar with what each symbol actually does takes about five minutes and pays off every time you use the unit.
This article covers the four main symbol groups you'll find on a Mitsubishi Electric remote: mode icons, fan speed symbols, airflow direction controls, and the timer and special function buttons. By the end, you'll know exactly what you're pressing and why.
Mode Symbols: The Most Important Icons on Your Mitsubishi Remote
These are the symbols you'll find on all Mitsubishi Electric split systems, regardless of the series. The mode button cycles through five operating modes, each represented by a distinct icon. Getting this right is the single biggest factor in how efficiently your unit runs. The exact icon style can vary slightly between the MSZ-AP and MSZ-LN series remotes, but the symbols represent the same functions across both ranges.
Cool Mode (Snowflake Symbol)
The snowflake icon activates cooling mode. Press it and the compressor kicks in, pulling heat out of the room and pushing it outside until the air temperature drops to your target setting. This is your go-to mode for Australian summers. For most people, a target temperature of 22 to 24°C hits the sweet spot between comfort and running costs. Setting it lower than you need won't cool the room faster, it'll just run the compressor longer and push up your power bill.
Heat Mode (Sun Symbol)
The sun symbol switches the unit into heating mode. Mitsubishi Electric split systems are reverse-cycle, meaning the same refrigerant circuit that cools in summer can extract heat from outside air and bring it indoors during winter. This makes them far more efficient than a resistive heater. For winter comfort, most households find 20 to 22°C plenty warm. Running it higher than that tends to create a stuffy feeling and draws more power without adding much comfort.
Dry Mode (Water Droplet Symbol)
This one trips people up constantly. The water droplet does not mean the unit adds moisture to the air. It means the opposite: Dry mode runs the system as a dehumidifier. The fan operates at a low speed and the compressor cycles on and off to remove excess humidity without aggressively dropping the room temperature. It's particularly useful on those muggy coastal Australian days where the air feels heavy and uncomfortable but it's not actually hot enough to justify full cooling mode.
Fan and Auto Mode Symbols
The fan or windmill icon runs the indoor fan only, with no heating or cooling active. The compressor stays off entirely, so you're just circulating air around the room. It's handy for mild days when you want airflow without the energy cost of running the refrigerant circuit. Auto mode, usually shown as circular arrows or the word 'AUTO', hands control to the unit itself. It reads the room temperature against your set temperature and decides whether to heat or cool to get there. It's a convenient set-and-forget option, though some people prefer to stay in manual mode for more predictable behaviour.
Fan Speed and Airflow Symbols on Mitsubishi Remotes
Fan Speed Settings
Fan speed is usually shown as a series of bars or lines that increase in height, similar to a mobile signal icon. Some remotes label the levels as LOW, MED, and HIGH, while others add two extra settings at either end: QUIET (or SILENT) and TURBO (or POWERFUL). AUTO fan speed, shown as circular arrows or the word 'AUTO', lets the unit choose the right speed based on how far the room temperature sits from your target.
QUIET or SILENT mode is worth knowing about. It's represented by a crescent moon or a 'Q' icon on many Mitsubishi remotes, and it drops the fan to its lowest possible speed to reduce noise. It's ideal for bedrooms at night when a humming fan is more annoying than the temperature itself. TURBO or POWERFUL mode does the opposite: it runs the fan and compressor at maximum output for around 20 minutes to hit your target temperature as fast as possible, then steps back to normal operation. Use it when you walk into a sweltering room and want results quickly, not as an all-day setting.
Vertical and Horizontal Airflow Swing
The vertical swing symbol looks like a louvre blade with arrows pointing up and down, or sometimes just a set of horizontal lines with a curved arrow. Pressing it sets the louvres to sweep continuously from top to bottom, distributing air across the whole room. If you press it again, the louvres stop at whatever angle they're currently pointing, locking in a fixed position. Horizontal swing works the same way but moves the airflow left and right, and is typically a separate button showing side-to-side arrows.
The angle you choose actually affects how efficiently the unit heats or cools. In cooling mode, aim the louvres upward toward the ceiling. Cool air is denser than warm air, so it naturally falls and spreads across the room without you needing to blast it directly at people. In heating mode, point the louvres downward toward the floor. Warm air rises on its own, so directing it low means it travels up through the room evenly rather than pooling uselessly at ceiling height. Higher-end models like the MSZ-LN series take this further with 3D Auto airflow, which combines both vertical and horizontal swing simultaneously so the unit distributes air in all directions automatically without any manual adjustment.
Timer, Sleep, and Economy Symbols Explained
These symbols sit in the less-visited corners of the remote, but they're some of the most useful for managing comfort and running costs day to day.
The ON Timer is shown as a clock face with an arrow pointing inward, or sometimes the word 'ON' next to a clock. It lets you schedule the unit to start at a set time, so you can walk into a cool room after work without leaving the system running all day. The OFF Timer is the reverse: a clock with an arrow pointing outward. Set it before you go to bed and the unit shuts itself off after your chosen delay, typically anywhere from 30 minutes to 12 hours depending on the model.
Sleep mode, shown as a crescent moon or 'ZZZ' icon, does something more subtle than just running quietly. It gradually raises the set temperature by one or two degrees over a few hours as your body temperature naturally drops during sleep. This means the unit works less hard through the night without you waking up uncomfortable. It's a smarter option than simply leaving the unit on at a fixed temperature all night.
Economy mode, labelled 'ECONO' or shown as a leaf icon, caps the maximum power draw of the unit. It won't cool or heat as aggressively, but it prevents the compressor from running at full load, which smooths out your electricity consumption. It's a practical setting for mild days when you don't need full output. If you want to understand how much your air conditioner costs to run, our real-numbers guide breaks it down for Australian households.
Some MSZ-LN series models also include a Weekly Timer function, shown as a small calendar grid icon. This lets you program different on and off times for each day of the week, which is genuinely useful if your schedule varies between weekdays and weekends.
Which Mitsubishi Model Are You Using? Symbols Can Vary
Most Mitsubishi Electric remotes share the same core symbols for mode, fan speed, and swing. But there are real differences between the entry-level MSZ-AP series and the premium MSZ-LN series that are worth knowing about, especially if a symbol on your remote doesn't match what you've read online.
The MSZ-AP series, such as the Mitsubishi Electric 2.5kW MSZ-AP25VGKD starting from $1,040, uses a straightforward remote with the standard mode icons, fan speed bars, and basic swing controls. It covers everything most households need, but the LCD display is compact and the button layout is minimal. If your remote looks simple and uncluttered, you're almost certainly holding an AP series remote.
The MSZ-LN series is a different story. The Mitsubishi Electric 2.5kW MSZ-LN25VGV at $1,901 comes with a more detailed remote that adds icons you won't find on the AP: a 3D Auto airflow button (combining vertical and horizontal swing in one press), a Weekly Timer function shown as a small calendar grid, and a larger backlit display with more information visible at a glance. If your remote has noticeably more buttons and a busier screen, you're likely on the LN series.
Both series are also compatible with MELCloud, Mitsubishi Electric's Wi-Fi control app, though built-in Wi-Fi is standard on the LN and optional on select AP models. MELCloud replaces the physical remote symbols entirely with clearly labelled on-screen controls, which many users find far easier to navigate than the physical icons. If you're regularly confused by your remote, setting up MELCloud is a practical fix. For larger spaces, the Mitsubishi Electric 5kW MSZ-AP50VGKD at $1,653 is a popular AP series option that follows the same remote layout as the 2.5kW model.

FAQ: Mitsubishi Air Conditioner Symbols
What does the snowflake symbol mean on a Mitsubishi air conditioner?
The snowflake symbol activates Cool mode, which runs the compressor to remove heat from the room and lower the air temperature. It's the standard setting for Australian summers. Set your target temperature between 22 and 24°C for the best balance of comfort and running costs.
What is the Auto mode symbol on a Mitsubishi remote?
Auto mode is typically shown as circular arrows or the word 'AUTO' on the display. In this mode, the unit reads the room temperature and decides whether to heat or cool to reach your set temperature, without you needing to switch modes manually. It's a convenient option for shoulder seasons when the temperature swings between warm days and cool nights.
What does the water droplet symbol mean on a Mitsubishi remote?
The water droplet represents Dry mode, which runs the unit as a dehumidifier rather than a cooler. The fan operates at low speed and the compressor cycles on and off to reduce humidity without aggressively dropping the room temperature. It's most useful on humid days where the air feels heavy but full cooling isn't needed.
Why does my Mitsubishi remote have symbols I don't recognise?
Less common symbols are usually tied to advanced features on premium models. A calendar grid icon indicates a Weekly Timer, a leaf or 'ECONO' label caps the unit's power draw, and a crescent moon activates Sleep mode, which gradually adjusts the temperature overnight. If a symbol still isn't clear, check your model's manual on the Mitsubishi Electric Australia website using your model number.
