Does your air conditioning remote scare you? Do you only press the power button and maybe the temperature up or down arrows in fear you may muck up the setting? Read on to find what your air conditioning remote symbols mean and what they do.
Do you look at the sun symbol and wonder if you use it on a sunny day to cool the room or on a winters day to heat the room? Most remotes for different brands of air conditioning units share the same features.
In this article we will explain what each symbol means and what it does.
The first button is the one that turns the air conditioning unit off and on. This is usually a different colour than the rest of the other buttons. It is usually orange or yellow but can also be red, blue or green.
It can have ON/OFF or START/STOP written on it or just have the POWER symbol which looks like the following.
One press to turn the unit on and another press to turn it off. Once turning the unit off the current settings will be kept and it will continue on these setting once the unit is turned back on.
The temperature buttons are usually up and down arrows with TEMP written by them. Pressing the UP button will increase the set temperature and pressing the DOWN button will decrease the temperature.
Most units have a MODE button which will cycle through the air conditioning units’ different operations. Fujitsu and Panasonic remotes have simplified things by having the words HEAT and COOL instead of small symbols to resemble the sun and a snow flake.
Most units will have a snow flake or ice symbol for the COOL mode. This mode is used to cool the room and would typically be used during summer.
The sun symbol represents HEAT mode. This is the opposite of the cool mode and is used to heat the room, usually during the cooler winter months.
A teardrop or water symbol is used to show the DRY mode. This mode is used to reduce the humidity in the room when the air is warm and very humid.
The indoor fan speed is automatically reduced in this mode so that the air spends longer moving across the indoor units cooling coils, to extract more moisture from the air. Dry mode can be an efficient and effective option in those conditions as reducing the humidity makes the air feel cooler and more comfortable. However if it’s very hot and only moderately humid, the cooling mode will be much more effective. The temperature cannot usually be increased or decreased in this mode.
The last symbol in the MODE setting is usually AUTO.
This mode will allow the unit to automatically select the cooling or heating mode depending on the set temperature. Unless you live in a climate where there are large temperature swings, (Melbourne) you are probably better of manually selecting the COOL or HEAT symbols.
The FAN setting is shown by a fan blade symbol.
This mode allows the unit to run as a fan only. As it just recycles the air in the room it neither heats or cools. The air may feel cool as it does the same job as a ceiling fan and the evaporation of body sweat on a hot day may feel like it is slightly cool.
The indoor fan speed can be controlled by pressing the FAN button. Each time you press the button the fan speed will increase as represented by the fan symbol on the remote screen. Most units have a minimum of 3 manual fan speeds and most newer units have up to 5 speeds. If you keep pressing the fan button you should eventually come to an AUTO FAN symbol. With this setting selected the unit will automatically select the fan speed depending on the current and set temperature. The unit will make the fan run at a high speed when it is first turned on and as the temperature approaches the set temperature it will reduce the fan speed, until eventually it is just ticking over on low speed. If the temperature in the room increases (in cooling mode) the fan will automatically adjust the fan speed to suit.
Some units also have a QUIET or SILENT fan option where the unit will run the indoor fan speed at a very low settings. This could be used at night time.
A POWERFUL or TURBO button can sometimes be found on some units.
This allows the unit to run the fan at maximum fan speed for maximum cooling or heating and to push the air further around the room. Some brands have a timer where after a set amount of time the unit will go back to its previous fan setting.
We suggest always leaving the fan on AUTO and let the indoor unit automatically select the correct speed.
The POWERFUL button should be used to quickly bring the room to the required set temperature.
Selecting a manual LOW fan speed should not be used when first turning the unit on as the unit will take a lot longer to cool/heat the room. Having the unit initially set to a low fan speed may not be enough to cool or heat the room. Higher fan speeds (or AUTO) allow the unit to quickly push the cool (or hot) air throughout the room. The greatest energy savings are once the room is close to the set temperature and the fan has automatically started to run on low settings. Not only is the unit running most economically it is also running very quiet.
Most units have a button that can control the vertical position of the louver. The louver is the horizontal blade that runs across the front of the unit. Pressing this button usually allows the blade to move to the next position up or down.
Each push allows another small movement and then the blade will move back up the other way. Sometimes each push of the button will eventually get to the auto mode where the louver will continually move up and down by itself. Sometimes there is a separate auto louver button on the remote that will do the same thing.
Some units also have an AUTO mode where the unit will select the best position for the blade – this is usually pointing across the room for cooling and down for heating.
Some units may have a button that allows the horizontal louver to move left and right to allow the air to move in this direction.
Sometimes each push of the button will eventually get to the auto mode where the louver will continually move up and down by itself. Sometimes there is a separate auto louver button on the remote that will do the same thing.
Most modern units have a timer function that allow the unit to turn on or off at or after a pre-set time. Some units have built in sensors that scan the room for movement. If no movement is detected after a certain amount of time, it will raise or lower the temperature to reduce energy costs.
Some brands like Panasonic have nanoe X technology that help in the inhibition of virus, bacteria, pollens and mould. Some units have special filtration that allows the removal of dust and can inhibit the growth of bacteria, mould and deodorise the air. SELF CLEANING functions can also be found on some units. This function is used once the unit is turned off and allows the indoor fan motor to be run at a very low speed to dry any moisture left in the air conditioning unit. This supposedly prevent mould build up.
