Mitsubishi Electric Corporation is a Japanese brand. World renowned brand for the manufacturer of a wide range of various electrical equipment and technical systems. There are a number of companies that have Mitsubishi in their word. And although formally there is no scheme that includes all these firms in a common holding, nevertheless, they are conditionally interconnected.
- air conditioning equipment (household, 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;
- car parts;
- and other electronic equipment.
The company currently develops and manufactures 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, the use of a logo.
Numerous offices, production sites, 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.
Mitsubishi Electric air conditioning systems
The company produces a full range of climatic equipment. In many ways, conditionally, air conditioning systems are divided according to their purpose into industrial, semi-industrial and domestic. The border between them is vague. 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
Such complexes are planned individually under the order and it is rather conditional to talk about some series of industrial equipment. In fact, in many cases, the same standard semi-industrial equipment is used: multisplit systems, channel, cassette, etc. Most often, floor units are used as the end device. This is due to the need for high refrigeration capacity, large equipment power, respectively, the dimensions and weight of the equipment can be impressive. A system of water cooling pipes is supplied to it.
Semi-industrial models
Two or more block systems have become more widespread. The usual implementation scheme is one outdoor vrv-unit and one or more indoor (vrf - multi-zone system). Sometimes the system also closes through several outdoor units in the expectation of redundancy in the event of failure of one of the units.
The following system markings are accepted:
- PLA - cassette;
- PKA - wall-mounted;
- PCA - ceiling-mounted;
- PEAD - channel;
- PEA - high pressure;
- PSA - Columnar.
The manufacturer even has specific models positioned exclusively for wine cellars.
Household wall appliances
The marking of household systems in the company is as follows. First, information about the indoor unit is indicated, through the fraction of the outdoor:
- The first letter is a series (M or S);
- Second letter. U - outdoor unit, S - wall-mounted, F - floor-standing, E - duct, L - cassette;
- Third letter. Z - inverter air conditioners, H - without inverter. The absence of the letter means that the system is inverterless, it works only for cooling.
The rest of the icons represent different types of models. For example, the letter H means that a heating element is built into the pallet, which heats the outdoor unit in winter.

Mitsubishi Electric Control Panel and Air Conditioning Instructions
The manual for Mitsubishi Electric air conditioners contains a description of the main operating modes of the equipment, recommendations for installation, adjustment, dismantling, service, as well as an explanation of errors.
The Mitsubishi Electric air conditioner must be installed by certified specialists. Otherwise, various negative consequences may arise. Wrong self-connection by the user and subsequent operation can lead to equipment failure.
Split system Mitsubishi Electric, 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 revision, for example, the installation of a winter kit, you also need to contact the specialists.
The remote control for the Mitsubishi Electric air conditioner can be of various modifications. The overview of the functions on the console depends on the specific equipment. All consoles provide control of the main operating modes: cooling, heating, dehumidification, ventilation. There is a timer mode. Other extensions are usually built into the consoles that come with devices that enable the appropriate modes: cleaning, ionization, supply ventilation.
Mitsubishi Electric air conditioner error codes
Mitsubishi Electric air conditioner error codes are standardized, universal. This means that the fault tables are in many respects similar in the passports of different models. And although there are no fundamental differences, it is recommended to use only the native manual.
The multisystem of diagnostics is developed.The program interrogates the status of sensors located in all major components of the equipment (compressor, inverter board, fan motor, evaporator, etc.) and the test results indicate possible malfunctions. The reaction depends on the severity of the malfunction and on the specific model: equipment shutdown, partial blocking of functions, activation of the purifier mode, etc. In any case, a notification will be generated for the user about how the system is working.
The lineup is very diverse and each model may have its own characteristics. In most cases, the operating parameters are displayed on the remote control. In developed systems, not only critical failures can be displayed, but also various routine, informational messages can be displayed: the need to replace the filter, pressure in the tubes, the state of the motor, pump, adapters, etc.
In addition to being reflected on the control panel, 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 row of LEDs blinks. A malfunction is indicated by the selection of combinations of duration, frequency and the order of blinking of the LEDs.
If a malfunction is indicated (without obvious signs of breakdown), it is recommended to restart the system. To do this, turn off the automatic fuse (the specialist must put a separate machine in the electrical panel), wait a few minutes and turn it on again. If the performance is not restored, then contact the service. The Mitsubishi Electric air conditioner should be repaired only by a specialized service. It is only allowed to independently change or clean the filter, external cleaning, in some cases flushing the drainage channels. If the equipment is disassembled before the expiration of the warranty period, then it may be removed from the warranty.
User reviews
Customer reviews are mostly supportive. The undoubted advantage is high quality. The main drawback is the size of the manufacturer's remuneration (the high cost of equipment when compared with similar products from competitors).
It is noted that the air conditioner is quiet, sometimes you cannot even distinguish that it is working. The impeller is balanced so that the fan is hardly audible. Especially in the case of under-ceiling design, when the air flow is dispersed smoothly throughout the entire volume of the room.
Users also note: design, functionality, ease of management, compliance with the declared characteristics.
