Instructions for Mitsubishi Electric air conditioners. Review of Mitsubishi Electric air conditioners: error codes, comparison of inverter duct, cassette and floor-ceiling models Remote control for Mitsubishi air conditioner instructions for use
Mitsubishi Electric Corporation is a Japanese brand. A world-famous brand of manufacturer of a wide range of various electrical equipment and technical systems. There are a number of companies that have the word “Mitsubishi” in their name. And although formally there is no scheme that includes all these companies in a common holding, nevertheless, they are conditionally interconnected.
Main production of Mitsubishi:
- air conditioning equipment (domestic, semi-industrial, industrial air conditioners);
- heating equipment (heat pumps, heaters, boilers, etc.);
- industrial automation;
- information and communication equipment;
- power equipment;
- equipment for apartments, kitchen, home;
- automobile spare parts;
- and other electronic equipment.
Currently, the company develops and produces both narrow, specialized devices and consumer goods. The range of manufactured products covers almost all manufactured electrical equipment - from batteries to space technology. The company's products meet the highest standards.
The company is the undisputed world leader. Therefore, you can often find fakes using the logo.
Numerous offices, production sites, and service centers are scattered almost all over the world. With the exception of Japan itself, there are more than 100 different structures around the world. The main research centers are located in Japan.
Air conditioning systems Mitsubishi Electric
The company produces a full range of climate control equipment. In many respects, air conditioning systems are conventionally divided according to their purpose into industrial, semi-industrial and household. The border between them is blurry. This means that the equipment is applicable in different places and rather the determining factor of feasibility will be the price - acquisition, operation, rotation, subsequent disassembly and disposal.
Industrial air conditioners
We will not consider it in detail. The choice of equipment largely depends on the purpose of the application. Such equipment is subject to increased requirements, both in terms of microclimate support and operational reliability. Such equipment is installed in server rooms, medical, scientific laboratories, etc. Very precise (up to one degree) temperature support is often required, which is provided by precision systems. Usually they combine a whole cascade, which is synchronized through a special matcher. The composition includes spare, backup equipment.
Such complexes are planned individually to order and talking about some series of industrial equipment can be quite conditional. In fact, in many cases the same standard semi-industrial equipment is used: multi-split systems, duct, cassette, etc. Most often, floor blocks are used as the final device. This is due to the need for high cooling capacity, high power of the equipment, and accordingly the dimensions and weight of the equipment can be impressive. A water cooling pipe system is supplied to it.
Semi-industrial models
They are divided into monoblock and multiblock. Monoblock systems are single-flow systems in which cooling and removal of excess heat are implemented in one unit. To remove excess heat, it is necessary to either place the equipment directly on an external wall or install an air hose. Such systems are mostly classified as industrial (it is easier to increase accuracy in one device).
Two or more block systems have become more widespread. The usual implementation scheme is one external vrv unit and one or more internal ones (vrf - multi-zone system). Sometimes the system is closed through several external units in anticipation of duplication in the event of failure of one of the units.
The following system markings are accepted:
- PLA – cassette;
- PKA – wall mounted;
- PCA – ceiling;
- PEAD – channel;
- PEA – high-pressure;
- PSA - columnar.
The manufacturer even has specific models positioned exclusively for wine cellars.
Household wall appliances
Mobile air conditioners have also been added to household air conditioners. But this is rather an exception; the company practically does not produce such systems and it is difficult to find them on sale.
The company has adopted the following markings for household systems. First, information about the indoor unit is indicated, followed by a fraction about the outdoor unit:
- The first letter is series (M or S);
- Second letter. U – outdoor unit, S – wall-mounted, F – floor-mounted, E – duct, L – cassette;
- Third letter. Z – inverter air conditioners, H – without inverter. The absence of a letter means that the system is non-inverter and works only for cooling.
The remaining icons indicate different types of models. For example, the letter H means that a heating element is built into the pan, which heats the outdoor unit in winter.
Comparative characteristics of several models
For comparison, we present the characteristics of several models.

Instructions for the control panel and air conditioners Mitsubishi Electric
The instructions for Mitsubishi Electric air conditioners contain a description of the main operating modes of the equipment, recommendations for installation, configuration, dismantling, service, as well as explanation of errors.
Installation of the Mitsubishi Electric air conditioner must be carried out by specialists who have the appropriate certificates. Otherwise, various negative consequences may occur. Incorrect independent connection by the user and subsequent operation may lead to equipment failure.
The Mitsubishi Electric split system, as well as multi split systems, consist of an external unit, which is usually mounted on a bracket to the wall of the house. Work can only be carried out by installers with the appropriate equipment and skills; in case of modifications, for example, installation of a winter kit, it is also necessary to contact specialists.
The remote control for the Mitsubishi Electric air conditioner can be of various modifications. The overview of functions on the remote control varies depending on the specific equipment. All remote controls provide control of the main operating modes: cooling, heating, dehumidification, ventilation. There is a timer mode. Other extensions are usually built into remote controls that come with devices that enable the corresponding modes: cleaning, ionization, fresh ventilation.
Error codes for Mitsubishi Electric air conditioners
Mitsubishi Electric air conditioner error codes are standardized and universal. This means that the fault tables are largely similar in the data sheets of different models. And although there are no fundamental differences, it is recommended to use only the native manual.
The multi-diagnostic system has been developed. The program queries the status of sensors located in all main components of the equipment (compressor, inverter board, fan motor, evaporator, etc.) and based on the test results, possible faults are indicated. The reaction depends on the severity of the malfunction and on the specific model: stopping the equipment, partially blocking functions, turning on the purifier mode, etc. In any case, a notification will be generated for the user about how the system works.
The model range is very diverse and each model may have its own characteristics. In most cases, operating parameters are displayed on the remote control. In developed systems, not only critical failures can be displayed, but also various regulatory and informational messages can be displayed: the need to replace the filter, pressure in the tubes, condition of the motor, pump, adapters, etc.
In addition to being reflected on the remote control, messages can be duplicated on the indicator, which is located on the body of the indoor unit, or under the cover. In models that do not have an indicator and a remote control, only a number of LEDs blink. A malfunction is indicated by selecting combinations of duration, frequency and order of LED flashing.
If a malfunction is indicated (without obvious signs of failure), it is recommended to restart the system. To do this, turn off the automatic fuse (a specialist must install a separate circuit breaker in the electrical panel), wait a few minutes and turn it on again. If performance is not restored, contact service. Repair of the Mitsubishi Electric air conditioner should only be carried out by a specialized service center. You can only change or clean the filter yourself, external cleaning, and in some cases flushing the drainage channels. If the equipment is disassembled before the warranty period expires, it may be voided from warranty.

To do this, you need to successively press the “Mode” button (No. 3). To set the temperature, use buttons No. 2.
Description of modes.
"AUTO" mode. To maintain the temperature, the air conditioner independently heats or cools the air supplied to the room, depending on the ambient temperature. Note: do not use this mode with a multi-split system when several indoor units are connected to one external unit. If one of them is turned on in heating (cooling) mode, all the others can only work in the same mode and therefore will not be able to switch between modes.
Heating - “HEAT” mode. Air heating. Note: when starting this mode, there may be a delay in the air supply at the beginning and stops for up to 10 minutes in operation - this is necessary to defrost the external unit.
Cooling - “COOL” mode. In this mode, the air is cooled and its temperature is maintained at a given level. Note: Do not use this mode when the outdoor temperature is below -10 degrees Celsius. This may damage the external unit.
Drying - “DRY” mode. In this case, the air conditioner cools minimally, drying the air in the room. You cannot set the temperature level in this mode.
Ventilation - “FAN” mode. The air conditioner circulates air in the room.
Additional settings for work
The indicator lights on the front panel can indicate three modes. Both light up when the mode has not yet been reached and the difference from the set temperature is more than 2 degrees. One is on, the other is off - the set temperature has been reached. The third mode can only be seen when the multi-split system is running. One is on, the second is blinking - this indoor unit has switched to standby mode, since the other is turned on in the opposite mode (for example, this one was cooling, and the other was turned on for heating).
Autorun function.
If the network was de-energized when the air conditioner was operating in the mode you specified, then after the power supply appears, it will automatically turn on in the same mode.
If it is not possible to use the remote control.
To control the air conditioner without a remote control, you can use the emergency button. By pressing it successively, you turn on the air conditioner in the cooling-heating-off mode. For the first 30 minutes after startup, the ventilation mode is set to maximum and the set temperature is not taken into account - the device operates in the maximum possible cooling/heating mode.
By pressing the FAN button you can set the fan operating mode. These can be Auto, quiet, weak, medium, strong, forced. By pressing the VANE button you can select one of the following operating modes: Auto, manual with five tilt options, “Swing” (regular rocking of the guide).

Cleaning your air conditioner
Memo.
Before cleaning, do not forget to turn off the air conditioner from the network.
Do not touch metal parts.
Do not use gasoline, abrasive powders, or insecticides.
Do not dry air conditioner parts in the sun or near heat sources.
Do not use water hotter than 50 degrees.
Nanoplatinum filter.
This is a ceramic product coated with platinum microparticles. It purifies the air better than a catechin filter. Additional air purification is provided by an electrostatic air filter; it must be washed every three months. Monitor the condition of the filters to improve the quality of the air conditioner. Be careful as plastic parts are easily scratched, affecting their appearance.
If you think there is a problem
It is not possible to issue a single command using the remote control - check the operation of the remote control, the correct installation and the serviceability of the batteries.
The horizontal flap does not move. This may be normal for some operating conditions. Check for foreign objects or damage. Press the RESET button on the remote control.
It is not possible to control the position of the damper in some modes, when the electronics itself determine its position and movement.
After restarting, the air conditioner does not work for 3 minutes - this is normal and necessary for the safety of the air conditioner.
When heating the room starts, the air conditioner does not work for 10 minutes or stops operating for this time. This is necessary to defrost the external unit.
If you are using a multi-split (two indoor units), then keep in mind that both indoor units must operate in the same mode (both for cooling or both for heating), so if the second one is turned on in a different mode, the first one goes into standby mode.
If you think that the device does not cool or heat the air well enough, please check the following points. Are the doors and windows closed, is it too hot outside - this reduces the efficiency of the air conditioner, are the filters clean and are there any obstacles to the air escaping from the external/indoor units. If the problem persists, call a professional as there is a possibility that it is a refrigerant leak. This substance may lead to the formation of harmful substances in contact with fire.
Sounds. If sounds are heard during operation, this may be normal. When the temperature of the indoor unit changes, its plastic elements will make sounds. Also, the movement of condensate or refrigerant can also cause sounds.
If a strange smell appears in the exhaust air, check first of all its possible sources - the carpet, wall and other objects adjacent to the indoor unit.
When the air conditioner will not be used for a long time
Before turning it off for a long time, turn it on in heating mode for 3-4 hours. During this time, moisture will be completely removed from the indoor unit, which can cause fungal growth. Next, you need to turn off the device by pressing the shutdown button on the remote control. Then you should remove the batteries from the remote control and disconnect the air conditioner plug from the outlet.
To connect after a long period of inactivity, you need to wash the filters, check whether there are any obstacles to air movement at the outdoor and indoor units, insert batteries and set the time in the remote control.
Selecting an installation location and carrying out electrical installation work
Installation location
The air conditioner should not be installed in the following places.
Where there is a lot of machine oil.
In salty climates such as the coast.
In places where hydrogen sulfide gas is formed.
In places where there are emissions of petroleum products into the atmosphere.
Where high frequency or wireless equipment is used.
Where the air outlet from the external unit will be disrupted.
Where the noise from the operation of the external unit may disturb other people.
Precautionary measures.

Make sure that the plug and cord are intact and clean, and use only the original power cord. Do not remove the plug from the socket or turn off the switch while the air conditioner is running - you must first turn it off using the remote control. The device must be powered from a separate outlet. Do not stand in the way of the flow of cooled air, as this may have a negative impact on your health. The product should be used by people who have studied the instructions and do not have age or health restrictions that limit their ability to understand it. Children should use the air conditioner under adult supervision.
Installation work must be performed by service center specialists - do not do it yourself! Since refrigerant will be pumped during installation, all operations must be performed by qualified personnel. Before use, ensure that the device is properly grounded.
Do not insert fingers, pencils, or any other foreign objects into the openings on the air conditioner body as this may cause injury. Do not stand on the external and internal blocks, do not place foreign objects on them. Cleaning the indoor unit is permitted only to specialists with appropriate training.
Do not spray flammable substances or insecticides on or near the air conditioner. Observe correct polarity when using batteries in the remote control. Change both batteries at the same time.

Preparation before starting work
The air conditioner should only be connected to an outlet of the required rating; grounding is required. Install batteries (not rechargeable batteries) into the remote control. Do not use batteries of different types and charge levels for joint installation.
Selecting operating modes
Selecting operating modes
The following modes are available for the Mitsubishi Electric MSZ-HC25VA model:
automatic mode selection;
heating the room;
room cooling;
air dehumidification;
ventilation (taking into account the operation of the air filter, this mode cleans the air).
To start the mode that suits you, press the mode selection button on the remote control. Automatic temperature control mode is used to maintain the room temperature within the range you specify. When it rises above the required level, cooling is turned on, and if the room becomes colder, heating is turned on.
Heating will come in handy when it's cool. It should be remembered that when the mode starts, the fan in the indoor unit will not turn on immediately, but only when the heat exchanger warms up - this is the protection against the flow of cold air. In addition, in this mode, freezing may occur on individual elements of the external unit, so operation will stop from time to time to remove ice from the external unit.
Cooling mode reduces temperature and dampness. If you want to dehumidify a room without cooling it, then you need a dehumidification mode.
The dehumidification mode is fundamentally different in that the electronics try to extract moisture from the air while minimizing its temperature.
By ventilating the room, the air conditioner uses filters to simultaneously clean the air in it.
Additional modes and settings
Thanks to the presence of an inverter motor control system, this model has minimal impact on electrical wiring. To operate in any mode and start the engine, exactly the power that is needed is taken.
Due to the presence of bioactive substances similar to those found in green tea, the catechin filter copes more effectively with microorganisms than other types of filters.
Another important property of this model is the presence of an antioxidant filter. Special components destroy free radicals in the air, while working as a catalyst - without being consumed. Therefore, it will protect your health for a very long time without requiring replacement.
To save energy, there is an “Econo cool” mode. When operating in this case, the air conditioner consumes less.
Automatic restart. For your convenience, the system remembers the last operating mode and after an emergency power outage it will automatically start operating in the same mode.
Timer. To make it more convenient for you to use the air conditioner, a timer is provided for turning it on and off. You can specify the start and stop times of the device in advance, so that it will then turn on and off independently at the time you specify.
Useful tips
Avoid overcooling the room - this will be bad for your health and will cause waste of energy.
Watch the vertical damper - when heating, the air should be directed downwards, when cooling horizontally.
Close windows and doors to keep cold air indoors. Close curtains to prevent direct sunlight from heating up the room. Too many people in the room and heating devices on make it difficult for the air conditioner to work.
Keep your air filter clean - clean it every 2 weeks.
Ventilate the room regularly to avoid oxygen starvation.
To ensure cooling or heating reaches the desired level faster, first use the “Turbo” fan operating mode.
Cleaning your air conditioner
Be sure to use a stable support for work.
Before you start, unplug the air conditioner.
Do not use abrasives, solvents (including gasoline), or hot water. - this can damage the appearance of the plastic.
The filter in this model can be washed by hand and used many times. All parts of this conditioner must be dried in the shade after washing.
If you think there is a problem
If your air conditioner is not working, check that the plug is connected to the outlet and that there is voltage. The operation may have been disabled by the timer.
If you cannot turn on the device 3 minutes after turning it off, this is the work of the system that protects the air conditioner from frequent starts.
When dehumidifying, the indoor unit is constantly switched off. In this mode, the electronics dries the air by cooling it to a minimum, so the indoor unit will periodically stop.
When heating starts, the air conditioner does not work immediately. This is protection against the release of cold air - first the heat exchanger warms up, and then the fan turns on.
During heating mode, the air conditioner stops periodically for 10 minutes. This is necessary to defrost the ice of the external unit, which in this mode is periodically covered with ice.
In heating mode, white smoke comes out of the external unit. Cold air coming out of the outdoor unit causes condensation to appear in the air.
There is fog coming from the indoor unit. Cold air from the indoor unit in a room with high humidity will cause fog to appear in the contact area.
After the energy appeared, the air conditioner began to work on its own. The auto-restart system will automatically start the air conditioner to operate in the mode in which it was operating before the power supply was cut off.
Water is leaking from the outdoor unit. This is a normal phenomenon - when heating and cooling, there will be parts in it that are colder than the surrounding air, on which condensation or even ice will appear.
The image on the remote control has become worse or disappeared. Check the presence and condition of batteries. Check that they are installed correctly.
The air conditioner does not heat/cool. This may be due to a refrigerant leak, please contact your service company.
The air conditioner does not cool the room well. If there are too many people in the room or there are heating devices, then its operation will be difficult. Make sure that the windows in the room are locked. If the curtains are open, sunlight will heat the room and interfere with the operation of the air conditioner. Check the condition of the air filter - if it is dirty, it creates a barrier to air movement. Check whether the operating mode is selected correctly.
There is a smell in the air from the unit. Check how clean the air filter of the indoor unit is. The smell may linger from surrounding objects (walls, wallpaper).
A cracking sound is heard. When plastic expands when heated, it will make similar sounds.
The sound of flowing water and dripping is heard. The flow of condensate and refrigerant may well cause these sounds. If the device is turned off, the sounds may be caused by the operation of the exhaust ventilation - air is sucked into the room through a hose to remove condensate.
When the air conditioner will not be used for a long time
Clean your air conditioner.
Turn on the heating for 2-3 hours. This will help dry the indoor unit and stop possible mold and bacteria growth.
Turn off the device using the remote control.
Disconnect the plug from the outlet.
To enable
Make sure there is somewhere for air to escape from the outdoor unit.
Connect the plug to the network, make sure that the grounding works correctly.
Install batteries (rechargeable batteries will not work) into the remote control.
Installation location and electrical work
Do not install the air conditioner in places with a salty, humid climate, where there is a lot of machine oil and hydrogen sulfide. It should not be placed in places where flammable gases may appear in the atmosphere and where the noise of the external unit will disturb residents.
Please note that it is necessary to provide where to drain the condensate from the external unit. The connection must be made by experienced specialists.
Precautionary measures
Do not operate the air conditioner in places with a salty and humid climate, where there is a large amount of machine oil and hydrogen sulfide. It should not be placed in places where there may be flammable gases in the atmosphere, or where noise from operation will disturb residents.

Air conditioning has become an integral part of the daily lives of most people. It is used at home, in offices, shopping centers - almost everywhere. With its help you can easily and quickly both cool and heat a room. But with huge demand, most consumers do not really know about all its capabilities. No fewer people have little understanding of the symbols of the buttons on the air conditioner remote control. This article will help you understand this issue.
Types and features
Air conditioner remote controls are divided into:
- infrared;
- wired.
Infrared remote controls are those that transmit a signal through radiation. This system is used in wall-mounted split systems, cassette, ceiling air conditioners, as well as in some models of window air conditioners. Infrared remote controls are convenient to use, but their range is limited to 8 meters, and it must be taken into account that after 5 meters malfunctions may occur due to bright lighting. This type of control is not suitable for systems installed above the recommended values, as well as for those models whose internal units are hidden behind suspended ceilings or plasterboard structures.
Infrared remote controls have a self-diagnosis system, so during a failure, the indicator lights on the internal unit of the split system begin to flash, thanks to which the service department will need less time for diagnostics and repairs.
Wired ones control the air conditioner at any distance. If there is a malfunction, an error code is displayed on the display, which makes diagnostics even easier than with an infrared remote control. The wired type of control allows you to control the operation of 4-8 air conditioners. Some models also include a temperature sensor to help ensure optimal performance.
NEAT
Regardless of the manufacturer of the split system, you can highlight the main symbols on the air conditioner remote control.
NEAT - heating, temperature up to 30 degrees. This mode is used to heat indoor air. It is marked on the air conditioner control panel in the form of a sun. The program automatically adjusts the temperature to the set temperature as soon as it starts to drop. It is important to know that each device has its own limitations when used in cold weather. Operational restrictions can range from -5 to -15 degrees depending on the technical characteristics of the air conditioner. Do not neglect the rules for operating the device to avoid breakdowns. When choosing an air conditioner, it is important to know the conditions under which it can be used. There are models that have no restrictions.
COOL
This mode cools the room in hot weather to 16-18 degrees. This function is considered the main one and is present in any air conditioner. It is marked on the air conditioner remote control in the form of a snowflake. Cooling occurs thanks to the filled refrigerant, which slowly takes heat from the room due to gas formation and releases warm air to the street. The power of the air conditioner should be selected at the rate of one kilowatt per 8-10 square meters, under such conditions the device will work most optimally. When using the cool mode, the most favorable temperature is 16-18 degrees; if this is not enough, you can turn on the fan.
DRI
The dehumidification function is designed to change the set temperature by several degrees for active removal in the room. This mode is identical to COOL, but at very low fan speeds of the indoor unit of the split system. Combining the function with room cooling means providing more comfortable air. The DRI mode helps to quickly dry the space and get rid of high humidity, make it easier to tolerate heat and stop the development of mold. Some air conditioner models have special sensors that automatically turn on this function if there is a deviation from the norm. For example, there is this designation on the Gree air conditioner remote control. In this mode, humidity levels cannot be programmed and maintained.
Air dehumidification occurs in this way:
- The fan is active for the first 10 minutes.
- The next 5 minutes are on pause.
- Then intensive ventilation is carried out for 2 minutes.
This mode should not be used near open sources of moisture, such as a swimming pool. In this case, other drying methods should be used.
FAN
The function is similar to a fan; it is used to change the blowing speed of the air conditioner. In this mode, cooling and heating equipment does not function, but only air is taken from the street. Suitable for houses with central heating. In some models, you can only turn on the ventilation of the room without taking air from the street. Manufacturers most often provide customers with a choice of 3 rotation speeds, and the mode independently selects the most suitable blowing speed.
AUTO
The function maintains a room temperature of 22-24 degrees, as it is considered the most comfortable for humans. The set value is adjusted every half hour. In this mode, temperature indicators are not displayed on the control panel display.
TURBO
A mode in which air flows at high speed throughout the room. If it is possible to turn off the air intake from the street, you can quickly mix the layers of air. This way the room temperature will be the same.
SLEEP
The mode is used during sleep to create favorable conditions. In this mode, the temperature changes over 6-8 hours, gradually increasing or decreasing the air temperature by 1 degree in order not to overcool or overheat a sleeping person. If the air conditioner works for heating, then the temperature increases, if for cooling, it drops.
SWING
Using this mode, you can fix or change the position of the split system blinds. Thanks to this mode, the air is distributed evenly throughout the room. Some remote controls display the movement of the blinds.
AUTORESTART
This mode is not indicated on the control panel, but its presence is very important. This program is triggered in the event of an unexpected power outage, automatically resuming the operation of the air conditioner in the specified mode when electricity appears again.
Standard modes
The main functions of an air conditioner are: dehumidification, cooling and heating of indoor air. The modes and their designation on the air conditioner remote control should be studied in advance in order to know the technical capabilities of the equipment. Cooling occurs due to the transition of the liquid state of the refrigerant into the gaseous state, which is carried out due to the intake of warm air from the room, and when heating the process occurs in the opposite way.
Each air conditioner has basic modes and additional ones, which directly depend on the manufacturer and model of the device. Designation of icons on the air conditioner remote control:
- Cool - cooling, looks like a snowflake.
- Heat - heating, indicated on the air conditioner remote control with a sun.
- Dry - drying, image of a drop.
- Fan - a fan with a corresponding design.
- Sleep - night mode, star image.
- Lock - child protection.
- Led - display backlight for working in the dark.
Special abilities
Some manufacturers, in pursuit of consumers, are trying to improve air conditioners with additional options. Some of them become very useful after use. So, special features include:
- Comfort setting - can turn on the air conditioner to calculate the optimal mode. As a rule, in this mode, 20 degrees is considered optimal for heating, 25 degrees for cooling the room.
- Air purification - occurs thanks to built-in filters of varying degrees of purification. It can be coarse - it helps to remove large particles of dirt, and fine - it can even cope with flower pollen. In addition, the air conditioner can be equipped with filters that absorb odors. Street dust settles on the filters, and the air in the room always remains fresh. This designation can be found on the Samsung air conditioner remote control.
- 3D flow - directs vertically. The consumer uses this function when he is afraid of catching a cold. It will be marked lfeel on the air conditioner remote control.
- Ionization - saturates the room with ions with negative charges. The option is intended to improve a person’s immunity and well-being. Reviews from some consumers say that during ionization a feeling of breeze appears. There is this designation on the LG, Mitsubishi air conditioner remote control in some models
- Filtration and air purification - this function is not available in all air conditioner models; it is carried out using step filters. It helps clean the air from dust, dirt and various microorganisms, and also helps get rid of unpleasant odors. This function is indispensable for people prone to allergies and pet owners.
- Defrosting the heat exchanger - maintains the performance of the air conditioner for a long time. In this mode, during cooling, the load on the refrigerant during cold collection is reduced.
The set of additional functions directly depends on the manufacturer and model of the split system. The symbols on the Mitsubishi air conditioner remote control will differ from the same meanings from other manufacturers. Before purchasing a unit, you need to consult with the seller or familiarize yourself with the options using the instructions included in the kit.
So, each air conditioner is equipped with the following functions: dehumidification, heating and cooling of air. In addition, each manufacturer tries to surprise the consumer and diversify the capabilities of the device. Therefore, when choosing an air conditioner, it is important to study the set of functions of the model you like.
