Mitsubishi Electric Corporation is a Japanese brand. A world famous brand of a 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 companies in a common holding, nevertheless, they are interconnected conditionally.
The 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;
- car parts;
- and other electronic equipment.
Currently, the company develops and manufactures both narrow, specialized devices and consumer goods. The range of products covers almost all electrical equipment manufactured - 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. Only with the exception of Japan itself, there are more than 100 different structures in the world. Major research centers are located in Japan.
Air conditioning systems Mitsubishi Electric
The company produces a full range of climatic equipment. In many respects, conditional 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 expediency will be the price - acquisition, operation, rotation, subsequent disassembly and disposal.
Industrial air conditioners
We will not consider in detail. The choice of equipment depends largely on the purpose of the application. Such equipment is subject to increased requirements, both in terms of microclimate support and reliability. Such equipment is installed in server, medical, scientific laboratories, etc. Often, very accurate (up to one degree) temperature support is required, which is provided by precision systems. Usually they combine a whole cascade, which is synchronized through a special coordinator. The structure includes spare, duplicating equipment.
Such complexes are planned individually under the order and it is possible to talk about some series of industrial equipment relatively conditionally. 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 large cooling capacity, high power equipment, respectively, 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-threaded systems in which cooling and excess heat removal are implemented in one unit. To remove excess heat, either equipment is placed directly on the external wall or an air hose is laid.Such systems are for the most part classified as industrial (it is easier to increase accuracy in one device).
Two or more block systems became more widespread. The usual implementation scheme is one external vrv block and one or more internal ones (vrf is a multizone system). Sometimes the system closes and through several outdoor units in the calculation of duplication in the event of failure of one of the blocks.
The following system markings are accepted:
- PLA - cassette;
- PKA - wall mounted;
- PCA - ceiling;
- PEAD - channel;
- PEA - high pressure;
- PSA - columned.
The manufacturer even has specific models that are positioned exclusively for wine cellars.
Household wall appliances
Mobile air conditioners have also been added to household air conditioners. But this is rather the exception, such systems are practically not released by the company and it is difficult to find them on sale.
The labeling of household systems in the company is adopted as follows. First, information about the indoor unit is indicated, through a fraction about the outdoor:
- The first letter is a series (M or S);
- Second letter. U - outdoor unit, S - wall, F - floor, E - channel, L - cassette;
- Third letter. Z - inverter air conditioners, H - without inverter. The absence of a letter means that the system is inverter-free, it works only for cooling.
The remaining icons indicate different varieties 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

Instructions for the control panel and air conditioners Mitsubishi Electric
Instructions for air conditioners Mitsubishi Electric contains a description of the main modes of operation of the equipment, recommendations for installation, configuration, dismantling, service, as well as decoding of errors.
Mitsubishi Electric air conditioning must be installed by qualified personnel. Otherwise, various negative consequences may occur. Erroneous independent 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 completion, for example, installation of a winter kit, you also need to contact specialists.
Remote control for air conditioner Mitsubishi Electric can be of various modifications. The overview of functions on the remote depends on the specific equipment. All consoles provide control of the main operating modes: cooling, heating, drainage, ventilation. There is a timer mode. Other extensions are usually built into consoles that come with devices that turn on the appropriate modes: cleaning, ionization, fresh air.
Error codes for Mitsubishi Electric air conditioners
Mitsubishi Electric air conditioner error codes are standardized, universal. This means that the fault tables are largely 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 polls the status of sensors located in all the main components of the equipment (compressor, inverter board, fan motor, evaporator, etc.) and the results of the test indicate possible malfunctions.The reaction depends on the degree of criticality of the malfunction and on the specific model: equipment shutdown, partial blocking of functions, inclusion of the cleaner mode, etc. In any case, a notification will be generated for the user about how the system works.
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 regulatory, 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 the reflection on the remote control, messages can be duplicated on the indicator, which is located on the case of the indoor unit, or under the cover. In models in which there is no indicator and remote control, only a series of LEDs blink. The malfunction is indicated by the selection of combinations of duration, frequency and the order of flashing LEDs.
When indicating a malfunction (without obvious signs of failure), 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 does not recover, then contact the service. Mitsubishi Electric air conditioning must only be repaired by a specialist service. It is only allowed to change or clean the filter on its own, external cleaning, in some cases flushing the drainage channels. If you disassemble the equipment before the expiration of the warranty period, then it can be removed from the warranty.
User reviews
Customer reviews are mostly supportive. The undoubted advantage is high quality. The main drawback is the amount of remuneration to the manufacturer (high cost of equipment, when compared with competitors).
It is noted that the air conditioner is quiet, sometimes it is not even possible to distinguish that it works. Impeller balancing is such that fan operation is almost inaudible. Especially with the sub-ceiling version, when the air flow disperses smoothly throughout the entire volume of the room.
Users also note: design, functionality, ease of management, compliance with the declared characteristics.
