Two or more indoor units can be served by one outdoor unit.
When several indoor units operate simultaneously, they should be used for
the same task (heating or cooling). If heating is selected on one and
then the second one turns on in cooling mode, then the first one goes into standby mode (standby).

OPERATING MODES
I FEEL mode
In this mode, the air conditioner itself selects the type of operation, depending on the temperature in
indoors. If the temperature is higher than the set one (for example 25° C, but 24 is set), then it
switches to COLD mode. When it reaches 24 ° C, it automatically switches to
DRY . If the temperature is below 23° C, the air conditioner will switch to HEATING mode.
Note:
When operating in COLD mode, it is impossible to change the set room temperature if
its value is higher by more than 2° C. It is necessary to wait until the air cools and only
then change this value.
COOL mode
Cooling the air in the room to a given temperature and maintaining it at a given temperature
level.
DRY mode
Dehumidifying your premises. The air may cool down a little. Desired temperature
cannot be set at all in dry mode.

CHARACTERISTICS

Mitsubishi Electric Corporation is a Japanese brand. Worldwide famous brand 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 ways, 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 and high power of the equipment; 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 error codes.

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.
