Air conditioning has become a part of everyday life for 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 homes 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 setpoint 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. Thus, the temperature in the room 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 consoles 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 by an unexpected power outage, independently resuming the operation of the air conditioner in the specified mode, when the electricity appears again.
Standard modes
The main functions of the air conditioner are: dehumidification, cooling and heating the air in the room. 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 a gaseous state, which is carried out due to the intake of warm air from the room, and when heated, the process occurs vice versa.
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 by the sun.
- Dry - dehumidification, image of a drop.
- Fan - a fan with a corresponding pattern.
- Sleep - night mode, star image.
- Lock - child protection.
- Led - backlight display 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 as a result of operation. So, the special features are:
- Comfort setting - is able to turn on the air conditioner in the mode of calculating the optimal mode. As a rule, in this mode, 20 degrees for heating is considered optimal, 25 degrees for cooling the room.
- Air purification - occurs thanks to the built-in filters of various degrees of purification. It can be rough - it helps to remove large particles of dirt, and fine - it can even cope with 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. In the reviews of some consumers it is said that during ionization there is a feeling of a breeze. There is this designation on the LG, Mitsubishi air conditioner remote control in some models
- Air filtration and purification - this function is not available in all models of the air conditioner, it is carried out due to stepped filters. It helps to clean the air of dust, dirt and various microorganisms, and also helps to 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 the collection of cold 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.
1. Saving electricity consumption
Controlling "felt temperature"
I SEE is an infrared sensor that scans the temperature at the floor surface in a 150-degree segment, and the control system can calculate the temperature perceived by a person.
Traditional air conditioners measure the level of air temperature at the entrance to the unit, and it is usually located high, and the temperature below the room may not always be optimal for the user. I SEE remotely measures the temperature in the lower sector of the room, which makes this function indispensable for children's rooms.
Zoned heating and cooling
I SEE - an infrared sensor - scans the temperature near the floor surface in a selected zone and reduces the area where the temperature differs significantly from the target values. This mode zone-conditions rooms, providing comfort and reducing energy consumption.
Econo Cool mode
Increasing the set temperature by 2C during cooling reduces energy consumption by 20%. And in order for the user not to pay attention to the increase in temperature and loss of comfort, the air conditioner provides a special algorithm for the operation of the blinds.
The air is supplied either vertically or horizontally downwards, in turn. The microprocessor calculates and sets the intervals and duration of the cycles, taking into account the temperature of the evaporator and the temperature in the room at the moment.
"I Feel" mode
When not knowing the comfortable temperature level for a person, the user often sets a very low temperature on the remote control - 16C in summer, and 26C and higher in winter. “I Feel”, using a microprocessor, independently determines the optimal temperature for the user, self-learning taking into account the previous parameters.
Performance mode
An external signal can limit system performance and, as a result, power consumption. In this mode, power consumption is reduced to the value set by switches SW7-1, SW7-2 located on the control board of the external unit:
0% (off) – 50%-75%-100% (no restrictions).
2. Appearance
Decorative panels
Elements of decorative panels made of plastic and metal are painted in bright white, appropriate in the color schemes of any interior.
Automatic damper
The damper is horizontal and closes automatically when switched off. Completely closes the hole from which air and parts of the air distribution system come.
3. Air purification
Double plasma cleaning
Dual Plasma - a filtration system - works on the principle of the disintegration of large molecules in an electric field, ionization of molecules, and neutralization of radicals with a catalyst. Due to this, the system captures micro- and nanodust particles and aromatic compounds.
Filtration
The air is cleaned of dust and pollutants, creating a healthy atmosphere in the home.
Antioxidant filter
A filter with a catalytic coating from the group of flavonoids reduces free radicals to chemically inactive molecules. The substance itself is not consumed. Due to this, the filter operates for up to 10 years.
Mitsubishi Electric has introduced an antioxidant into ceramic fibers embedded in a polypropylene mesh, so the filter can be easily washed and wiped, unlike filters in which catalysts are applied to polypropylene in the form of a film that is quickly erased during operation.
Oil filter
Holds oil suspensions and prevents oil from entering the block.
Air flow
Fresh air enters the room, which improves its composition and quality.
Enzyme anti-allergen filter
Eliminates bacteria and dust. Allergens do not accumulate in the filter, being decomposed by catalysts into safe compounds.
Long life filter
Polypropylene filter fibers are specially “activated” for filtration and increase the interval between service treatments.
High efficiency filter
Additionally, it filters the air and retains small particles that have passed through the pre-filter.
Filter check reminder
At selected intervals, a reminder appears to prompt you to clean the filter.
4. Air distribution system
Swing of the horizontal damper
The presence of this mode allows you to evenly distribute air throughout the room.
Swing of vertical guides
This mode supplies air to all areas of the room evenly.
High ceiling rooms
For them, an increase in the flow rate and speed of air flow at the outlet of the indoor unit is provided in order to achieve the required air mobility at the bottom of the room.
Low ceiling rooms
They are designed to reduce the flow rate and air flow rate at the outlet of the indoor unit in order to achieve low air mobility in the working area of the room.
Automatic fan speed
When approaching certain temperature parameters, the fan speed in the indoor unit decreases automatically.
Powerful air flow
To condition a large area or complexly shaped rooms, a wide air flow is required (150 degrees when heating, 100 degrees when cooling. “Wide Swing” button on the remote control with a choice of air supply method from seven proposed options) and a long flow length (“Long Airflow” button , when pressed, the length of the air jet increases to 12 m).
5. Comfort and convenience
24 hour week timer
Organizes the automatic operation of the air conditioner during the week. For each day of the week there are 4 on/off switches and a change in the set temperature.
12 hour timer
The timer is set for the next 12 hours. The discreteness of its installation is 10 minutes.
“I Save” mode
One press of a button puts the system into a low power consumption mode. This is convenient to use when the user goes to bed and uses the “I Save” mode button to change the air conditioner to heat the air to 18C. In the morning, the same button will reset the system to the previous setting of 22C.
This function is also convenient when used in economical standby heating, for example, in a country house. Models MSZ-GE/MUZ-GE are able to maintain a standby temperature of +10C.
Automatic mode change
The system automatically switches cooling or heating modes to maintain the set temperature.
autorun
The air conditioner returns to the previous set mode automatically if, for example, the power was previously turned off.
Cooling at low temperature
The outdoor unit control changes the fan speed to stabilize the refrigerant condensation pressure, allowing the room to be cooled when the outside temperature is low.
"Night" mode (external unit)
The noise level of the external unit is reduced. It is necessary to take into account that productivity in this mode is also reduced.
Limiting electricity consumption
A DIP switch on the control board of the outdoor unit sets the power consumption limit.
Fixing the operating mode
The DIP switch on the control board of the external unit can fix the operating mode. For example, in summer users will not be able to turn on the air conditioner in heating mode, or in winter - in cooling mode.
6. Management and control
Control panel PAR-21MAA or PAR-30MAA
It is possible to connect these remote controls with many functions, a built-in weekly timer and a Russified interface.
Central on-off
Air conditioners are connected to the central controller MAC-821SC-E, which is responsible for switching on/off and indicating the status of groups (no more than 8).
Group management
One remote control can set operating parameters simultaneously for several (up to 16) air conditioning systems.
Connection to MXZ multi-systems
The indoor unit can be used as a component of inverter multisystems based on MXZ external units.
Synchronous multisystem
From two to four (depending on modification) internal units can be connected to one external one. The indoor units in this system will work synchronously. This multi-system is optimal in large mono-volume rooms.
M-NET signal line
The described devices can be connected to the signal line of multi-zone system controllers (M-NET controllers), for example the AG-150A controller.
Rotation, inclusion of an additional system and redundancy
Rotation and redundancy: 1. The main and backup systems alternately operate at a given interval, equalizing the operating time. 2. If the working system fails, the standby system is switched on.
Additional system: 1. When the temperature rises and exceeds the set value by a set value (4, 6, 8C), the backup system is turned on in addition to the operating main one. 2. When the set temperature drops by 4C, the backup temperature is turned off. 3. This function only works when the backup is in cooling mode with the rotation function active.
Automatic connection correction function
Determines the compliance of connections of freon wires and signal lines. In case of discrepancy, correctness is automatically restored - programmatically. It takes 10-30 minutes to check for correctness.
*the function is used only in cooling mode when the outside temperature is above 0C. Sometimes the mode cannot determine the correctness - when the valves are closed, there is a refrigerant leak, expansion valves are faulty, etc.
Built-in drain pump
Organizes the rise of the drainage line and effectively removes condensate.
Collecting refrigerant into the outdoor unit
To condense freon from the line into the external unit (when dismantling or moving the system), a “Refrigerant collection” button is provided.
Flange connections
They simplify installation without requiring soldering of freon wires.
7. Service
Collapsible body
Elements of the air distribution system can be removed for cleaning without using special tools. Cleaning interior parts promotes cleanliness and comfort in the room and increases energy efficiency.
Self-diagnosis
The fault code is displayed on the remote control display, which simplifies diagnostics.
Fault code archive
When the system is operating, fault codes are recorded in non-volatile memory and can be checked during diagnostics.
Anti-mould coating for drainage tray
The drain pan is coated with a compound that prevents the appearance and growth of mold.
Mitsubishi wall-mounted air conditioners are available in two series:

Inverter air conditioners mitsubishi (Mitsubishi)
Mitsubishi semi-industrial inverter air conditioners are represented by 3 types of outdoor modules. These are the Standard, Zubadan and Power series.
Power range from 3.5 to 25 kW. Each series has models operating on 220 and 380 Volts.
Semi-industrial inverter air conditioners mitsubishi (Mitsubishi) are distinguished by increased routes up to 120 meters, with a height difference of up to 50 meters.
One external module is able to serve 4 internal ones.
- Models of the ZUBADAN series operate at external temperatures up to -25 for heating and up to -15 for cooling;
- Advanced self-diagnosis system;
- When installing mitsubishi Power series inverter air conditioners, you can use tubes of several sections. These models are suitable instead of outdated ones that were charged with R22 refrigerant;
- The power of Mitsubishi air conditioners of the ZUBADAN series does not change when the outside temperature drops to -15 degrees. Further, the figure gradually decreases, but it is higher than that of conventional other inverters, including the Power series.
Split systems mitsubishi (Mitsubishi)
Mitsubishi split air conditioner is one of the market leaders. The success is explained by the high reliability of models in all price ranges. During the production process, split systems are subjected to serious tests, which significantly exceed the loads possible in real life.
Operating at maximum power in dusty air, in frost or heat is not a problem for Mitsubishi split air conditioners. The advantage over equipment from other manufacturers is the ability to use even at low temperatures. Air conditioners (Mitsubishi Heavy) will not be damaged by temperatures below -20 degrees.
The length of the route during installation can reach 25 meters, and the difference in heights can be up to 12 meters.
Very easy control of air conditioners, innovative solutions for mitsubishi air conditioner remote controls make their use simple and comfortable.
The minimum noise level and quiet modes allow them to be used at night and in children's rooms.
Mitsubishi air conditioners purify indoor air thanks to plasma filtration and an antioxidant purification system.
Most mitsubishi heavy air conditioners operate in hot-cold mode. You can also find economy class models that only cool the air. Without exception, all models of Mitsubishi air conditioners operate on safe R410a freon.
Multi-split systems are the ability to connect several indoor modules to one outdoor module and simultaneously serve the entire apartment or multi-room office. This is not a cheap technique, but you have to pay for quality.
Mitsubishi cassette air conditioners
The corporation produces single-flow and four-flow Mitsubishi cassette air conditioners, all models operate on inverter control.
Single-flow cassette air conditioners Mitsubishi MLZ-KA-VA series are convenient for installation in rooms equipped with a suspended ceiling. The indoor unit fits in the opening between the main and false ceiling, which is at least 17.5 centimeters.

Duct air conditioners Mitsubishi
Mitsubishi duct air conditioners are designed for halls of complex shape, multi-room offices or apartments. Cooled air enters rooms through ducts or ducts. The air conditioner module is mounted in a utility room or under a suspended ceiling, and the air ducts are also located here. For proper installation, it is advisable to plan this type of climate system at the stage of building construction. During installation, the data from the Mitsubishi air conditioner instructions is used.
Mitsubishi duct air conditioners are able to renew indoor air by sucking in fresh air from the street. To use this function, you need to install a separate channel with access to the street.
Remote control for mitsubishi air conditioner
The control panel looks very ordinary. The location of the buttons is quite convenient, and even a child can understand the functions. To the extreme, all functions are always described in the operating instructions for the remote control.
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.
