Mitsubishi Electric Multi Split Set from the MSZ-LN series in Pearl White, Onyx Black or Ruby Red: three MSZ-LN25VG2 indoor units with 2.5 kW cooling capacity each connected to one MXZ-3F54VF3 outdoor unit with 5.4 kW cooling and 7.0 kW heating capacity, energy efficiency class A+++ for cooling and A++ for heating on the A+++ to D scale. SEER 8.52 and SCOP 4.61, 19 dB(A) on the lowest fan speed, 3D i-see sensor and WiFi control in each indoor unit, three rooms of approximately 19 to 25 m²^* each.

Performance and range

For the Mitsubishi Electric MXZ-3F54VF3 outdoor unit, the manufacturer states 5.4 kW cooling capacity with an adjustable range of 2.9 to 6.8 kW and 7.0 kW heating capacity with an adjustable range of 2.6 to 9.0 kW. The three MSZ-LN25VG2 indoor units are rated at 2.5 kW cooling and 3.2 kW heating capacity each, totaling 7.5 kW cooling capacity and thus 2.1 kW more than the outdoor unit; what this means in operation is explained in the frequently asked questions. The operating range is stated as minus 10 to plus 46 °C for cooling and minus 15 to plus 24 °C for heating. All three connections on the outdoor unit have 6 mm on the liquid side and 10 mm on the gas side.

Approximately 19 to 25 m²^* per indoor unit is a guideline for typical room height and standard insulation, not a binding design. Whether three rooms of this size are suitable for this configuration depends on room height, insulation, window area, shading and usage; we will clarify this upon request.

* Guideline based on the cooling capacity specified by the manufacturer, at a typical room height of approximately 2.5 m, standard insulation and average solar radiation. Different conditions on site, such as large window areas, sloped roofs or a high number of occupants, may require a different performance class. The binding design is carried out on an object-specific basis. For a professional design of your property, please contact us.

Frequently asked questions

In what colors is this set available?

Pearl White (model code MSZ-LN25VG2 V), Onyx Black (MSZ-LN25VG2 B) and Ruby Red (MSZ-LN25VG2 R) are available, selected via the color variant at the top of the page. One set contains three indoor units in the same color; performance, dimensions, features and price are identical for all three colors.

What cooling and heating capacity does the set have?

The MXZ-3F54VF3 outdoor unit is rated at 5.4 kW cooling capacity with an adjustable range of 2.9 to 6.8 kW and 7.0 kW heating capacity with an adjustable range of 2.6 to 9.0 kW. For each MSZ-LN25VG2 indoor unit, the manufacturer states 2.5 kW cooling capacity (1.0 to 3.5 kW) and 3.2 kW heating capacity (0.7 to 5.4 kW). The set is rated A+++ for cooling and A++ for heating on the A+++ to D scale, with SEER 8.52 and SCOP 4.61.

What do A+++ and SEER 8.52 mean for this set?

A+++ for cooling is the highest level on the A+++ to D scale and requires a SEER of at least 8.5; 8.52 is specified. A++ for heating requires a SCOP of at least 4.6; 4.61 is specified. These values apply to the combination of the outdoor unit and three indoor units, the same in every color. The power consumption of the outdoor unit is not stated on this page.

Can I control the system via an app?

Yes, in all three colors. The WiFi control is built into the MSZ-LN25VG2 indoor units; nothing is retrofitted; each of the three rooms appears separately in the app. Which app the manufacturer provides is not stated on this page; we will tell you upon request. Each indoor unit also comes with an infrared remote control with weekly programming and on/off timer.

How do three indoor units work with one outdoor unit?

The MXZ-3F54VF3 outdoor unit has three connections with 6 and 10 mm each; each indoor unit is connected via its own refrigerant line. The three rooms are controlled separately, via their respective remote control or the app; the outdoor unit adjusts its performance between 2.9 and 6.8 kW to the combined demand.

Is the outdoor unit sufficient for all three rooms at the same time?

Three times 2.5 kW results in 7.5 kW at the indoor units, the outdoor unit is rated at 5.4 kW. Only when all three rooms simultaneously request full load does the outdoor unit distribute its 5.4 kW; each indoor unit then gets about seven tenths of its nominal capacity. If one or two indoor units are running, they receive full power. The manufacturer provides for this configuration.

What rooms is this set suitable for?

According to the manufacturer, each indoor unit is suitable for approximately 19 to 25 m²^*: three bedrooms, master bedroom and two children's rooms, three offices, three hotel rooms, which do not constantly run at full load at the same time. The 3D i-see sensor in each indoor unit measures the temperature distribution in the room and directs the air accordingly. The binding design is carried out on an object-specific basis.

How many indoor units are included in the scope of delivery?

Three MSZ-LN25VG2 indoor units in the chosen color (V, B or R), three infrared remote controls and one MXZ-3F54VF3 outdoor unit. Not included are refrigerant lines, installation material and the console or bracket for the outdoor unit.

Is an installation set required for each indoor unit?

Yes, three identical ones: 6 mm (1/4") on the liquid side and 10 mm (3/8") on the gas side for each indoor unit, three times 6 and three times 10 mm on the outdoor unit. The color of the indoor unit does not change this. The material is not included in the scope of delivery and is measured by the specialist company according to the pipe routes.

How large and how heavy are the units?

The indoor units are stated at 890 x 307 x 233 mm and 15.5 kg, identical in all three colors. The outdoor unit is stated at 840 x 710 x 330 mm and 58 kg; it requires a floor console or a wall console designed for this weight, which the specialist company determines on site.

How loud is the system?

The indoor units are stated at 19 dB(A) on the low fan speed and 36 dB(A) on the high fan speed, the outdoor unit at 46 dB(A) in cooling and 50 dB(A) in heating mode. The page does not state a sound power level. In quiet mode, the fan of the respective indoor unit rotates even slower.

What filters does the indoor unit have?

According to the manufacturer, each indoor unit has an air purification filter and a silver ion air purification filter, identical for all three colors. The filters are part of regular maintenance and are cleaned or replaced, three times for three indoor units.

How far apart can the indoor and outdoor units be?

The maximum total pipe length, the length per indoor unit and the maximum height difference are not stated on this page; we will tell you these values upon request. Three pipes meet at the outdoor unit, which is therefore determined first.

Can I heat with the system in winter?

Yes. The heating operation is specified for outdoor temperatures from minus 15 to plus 24 °C, and the cooling operation from minus 10 to plus 46 °C. For heating, it is A++ on the A+++ to D scale, with a SCOP of 4.61; the outdoor unit delivers 7.0 kW, each indoor unit 3.2 kW with a control range up to 5.4 kW. The winter regulator keeps the outdoor unit ready for operation in cold weather, and the anti-freeze protection prevents the indoor unit from blowing cold air before the heat exchanger is warm. We can check whether the system can heat three rooms as the sole heating source upon request.

Can I install the air conditioning system myself?

No. Installation and commissioning are carried out by a certified specialist company. You need to plan for three pipe routes, three condensate drains, the electrical supply line, and a space for an outdoor unit weighing 58 kg.
