Mitsubishi Heavy air conditioner review: error codes, inverter models

Mitsubishi Heavy Industries is a Japanese concern that has been at the forefront in the field of HVAC equipment for industrial and domestic needs for many decades. The most successful project, which was developed by the best Mitsubishi engineers, is a multi-split system that allows you to connect to one outdoor unit. up to 5 indoor devices for microclimate control in several rooms.

Let us consider detailed information about the features of these systems, about the classification and recommendations of the manufacturer for the use of one or another modification.

Basic classification of air conditioning systems

Mitsubishi Heavy air conditioners are the optimal solution for any task requiring control and management of the microclimate both in an apartment and in a semi-industrial or industrial building. This is due to the fact that the systems are represented by the following modifications:

1. Mitsubishi Heavy wall air conditioners (SRK25ZXA-S / SRC25ZXA-S, SRK35ZS-S / SRC35ZS-S, SRK80ZSPR-S / SRC80ZSPR-S).
2. Floor (ceiling) inverter-type split systems for offices or shopping centers (SRF25ZMX-S / SRC25ZMX-S, FDEN125VD / FDC125VN, FDEN140VD / FDC140VNX).
3. Duct systems for integration with a centralized ventilation system (FDUM140VF / FDC140VN, FDU200VD / FDC200VS, FDU140VD / FDC140VN).
4. Column devices for semi-industrial buildings (FDF125VD / FDC125VS, FDF125VD / FDC125VSX, FDF100VD / FDC100VNX).
5. Mitsubishi cassette air conditioners for built-in installation in sales areas, exhibition areas, office premises, etc. (FDT140VD / FDC140VNX, FDT125VD / FDC125VS, FDT100VD / FDC100VNX).

Wall mounted air conditioner

This class of equipment is mainly installed in apartments, houses or offices. The competitive advantage of this particular class of equipment can be called:

1. The presence of special filters with enzymes patented by Mitsubishi, which purify the air entering the room from various bacteria and fungi.
2. An automated self-cleaning system that starts when the device stops working to dry the indoor and outdoor control unit and prevent the formation of mold and pathogenic bacteria.
3. Quiet operation in night mode. This effect was achieved through the use of special stabilizers, which, in addition to the uniform distribution of the air flow, ensure minimal contact of the air mass with the fan.
4. The presence of 8 operating modes: air conditioning, heating, turbo mode, automatic, dehumidification, air purification, ventilation, night.

Among the climatic equipment of Mitsubishi Industries, 3 models are in the widest demand (SRK20HG-S, SRK35ZMP-S, SRK25MA-S), the main technical characteristics are given in the table.

Duct air conditioners

This class of equipment for industrial and semi-industrial buildings is in extraordinary demand among legal entities and companies, since the Mitsubishi concern has no competitors in this market segment. This is due to the following characteristics:

1. Installation of the Mitsubishi Heavy air conditioner is carried out only by certified representatives of the concern, as a result of which the equipment will serve without breakdowns for 10-15 years.
2. High power. In the case of installation in a general air conditioning and ventilation system of the room, the efficiency of the equipment reaches 20 kW in cooling mode and 22.4 kW in heating mode.
3. The presence of a highly intelligent system that is integrated into the “Smart Home” system through the LonWorks and BACNet protocols;
4. Work in extreme conditions. inverter air conditioners of this class are capable of operating in an aggressive environment with a minimum temperature value of up to -20⁰FROM.
5. The presence of all kinds of sensors for the automatic operation of equipment and control of the functionality of each individual element of the system.

The brightest representative of this segment of HVAC equipment can be called FDU200VD / FDC200VS (FDU200VSV), which is able to control the microclimate in a room of 200 m².

Cassette air conditioner

All equipment of this class is manufactured in accordance with European standards, as evidenced by the presence of a quality certificate. Cassette air conditioners are installed both in office buildings and in small industries with an area of ​​up to 140 m² and have the following features:

1. Possibility of connecting several air conditioners to the Superlink automatic control system using the LonWorks and BACNet protocols.
2. The maximum length of equipment lines can be up to 50m.
3. The stator of the electric motor is manufactured using POKI POKI CORE technology, thanks to which the efficiency of the device is increased by 30%.
4. Cooling air in the room to a temperature of -10⁰FROM.

Air conditioners of this linear series are controlled from the multifunctional control panel PAR-31MAA or more simplified model PAC-YT52CRA

Manual for Mitsubishi Heavy control panel and air conditioners

To control the climate systems of Mitsubishi, you need a remote control for the Mitsubishi Heavy air conditioner. This device allows you to:

• Manage the temperature regime in the room.
• Enable "Night" or "Automatic" mode of the device.
• Adjust the speed and direction of the air flow.
• Manage multiple devices connected to a single multi-split system, etc.

For a more detailed acquaintance with the functionality of the remote control for Mitsubishi, we recommend that you familiarize yourself with the following photo, which will provide complete information about the purpose of a particular button, as well as options for the system.

Mitsubishi Heavy air conditioner error codes

Despite the fact that the company's products are of the highest quality, sometimes there are minor troubles that you can cope with on your own (cleaning the drainage system or filters) or you need the help of Mitsubishi specialists. To determine the nature of the breakdown, the instruction for Mitsubishi Heavy air conditioners will be useful, which can be found in the next photo.
