An indoor unit with 2.5 kW for the bedroom, one with 3.4 kW for the living room, and an MXZ-2HA40VF outdoor unit with 4.0 kW cooling and 4.3 kW heating capacity: this is the largest combination the manufacturer specifies for this outdoor unit. Both indoor units belong to Mitsubishi Electric's MSZ-HR series and have built-in Wi-Fi, so no additional module is required. The specified energy efficiency classes are A++ for cooling and A+ for heating on the A+++ to D scale, with an SEER of 8.0. As a guideline, the smaller indoor unit covers approximately 19 to 25 m², while the larger one covers approximately 26 to 34 m²^*.

Performance and range of use

The Mitsubishi Electric MXZ-2HA40VF outdoor unit has a specified cooling capacity of 4.0 kW and heating capacity of 4.3 kW. The MSZ-HR25VFK indoor unit has a specified cooling capacity of 2.5 kW and heating capacity of 3.15 kW, while the MSZ-HR35VFK indoor unit has a specified cooling capacity of 3.4 kW and heating capacity of 3.6 kW. The combined cooling capacity of the indoor units is 5.9 kW; the manufacturer expressly lists 2.5 plus 3.5 kW as the largest permitted combination for this outdoor unit. The outdoor unit's operating range is specified as minus 15 to plus 46 °C. The pipe connections on both indoor units and both connections on the outdoor unit are specified as 6.35 and 9.52 mm.

The stated area of approximately 19 to 25 m²^* applies to each indoor unit and represents guidelines for standard room height and normal insulation standards, not a binding design. The decisive factors are room height, insulation standards, window areas, shading, and the number of people and devices. We can check the appropriate design for your property upon request.

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

Detailed functions

Built-in Wi-Fi

Yes. The two MSZ-HR25VFK indoor units come with the Wi-Fi interface from the factory; no separate module is available for purchase for this set because none is necessary. The K suffix in the model code indicates this version. Which app the manufacturer provides for this is not stated on this page; we will tell you upon request. Two remote controls are included.

The largest combination for this outdoor unit

This set is exactly the combination the manufacturer specifies as the largest permitted for the MXZ-2HA40VF outdoor unit: one indoor unit with a 2.5 kW class and one with a 3.5 kW class. This outdoor unit cannot accommodate more, nor a third indoor unit, because it has two connections. Anyone who wants to supply three rooms needs an outdoor unit with three connections; we offer sets from the same series for that purpose.

Multi-split principle

Two indoor units connected to one outdoor unit, each with its own refrigerant circuit and remote control. Externally, there is one installation location and one supply line. Both pipe runs are identical because both indoor units have the same connection dimensions.

The MSZ-HR25VFK indoor unit has a specified cooling capacity of 2.5 kW and heating capacity of 3.15 kW, while the MSZ-HR35VFK indoor unit has a specified cooling capacity of 3.4 kW and heating capacity of 3.6 kW. The energy efficiency classes are specified as A++ for cooling and A+ for heating on the A+++ to D scale, with an SEER of 8.0 and an SCOP of 4.3.

Is this the largest combination for this outdoor unit?

This set is exactly the combination the manufacturer specifies as the largest permitted for the MXZ-2HA40VF outdoor unit: one indoor unit with a 2.5 kW class and one with a 3.5 kW class. This outdoor unit cannot accommodate more, nor a third indoor unit, because it has two connections. Anyone who wants to supply three rooms needs an outdoor unit with three connections; we offer sets from the same series for that purpose.

Can I control the system via an app?

Yes. The two MSZ-HR25VFK indoor units come with the Wi-Fi interface from the factory; no separate module is available for purchase for this set because none is necessary. The K suffix in the model code indicates this version. Which app the manufacturer provides for this is not stated on this page; we will tell you upon request. Two remote controls are included.

What operating modes does the system have?

Cooling, heating, dehumidification, and ventilation, so four. This is how the manufacturer specifies the operating modes for the MSZ-HR indoor units connected to the MXZ-2HA40VF outdoor unit. Each indoor unit fan has four fixed speeds and one automatic setting, and the air outlet flap swings up and down (vertical swing).

How do two indoor units work with one outdoor unit?

Two separate refrigerant circuits, one for each indoor unit, connected to a common outdoor unit. Each room has its own remote control and its own setpoint temperature.

Is the outdoor unit sufficient for both indoor units at the same time?

The two indoor units together have a cooling capacity of 5.9 kW, while the outdoor unit is specified with 4.0 kW. The manufacturer itself states that this difference is permitted by listing 2.5 plus 3.5 kW as the largest combination for this outdoor unit. In practice, this means: if one indoor unit runs alone, it has the full 4.0 kW; if both run at full load, they share the 4.0 kW and reach approximately two-thirds of their rated capacity. This is designed for two rooms that are not constantly under full load at the same time. For two rooms that are permanently used in parallel at full capacity, we can offer you a set with more outdoor capacity upon request.

For which rooms is this set suitable?

The 2.5 kW indoor unit is designed for approximately 19 to 25 m² according to the manufacturer, while the 3.4 kW one is for approximately 26 to 34 m²^*. The larger one belongs in the room that is used longer or has more window area, usually the living room; the smaller one in the bedroom, where its 21 dB(A) on the lowest setting counts. Both units have the same housing measuring 838 x 280 x 228 mm. We carry out the binding design on a property-specific basis.

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

Two: one MSZ-HR25VFK with 2.5 kW and one MSZ-HR35VFK with 3.4 kW, plus two remote controls and the MXZ-2HA40VF outdoor unit. Pipes, mounting material, and the bracket or console for the outdoor unit are not part of the delivery.

Is a mounting set required for each indoor unit?

Yes, two, and although the indoor units have different capacities, both sets of pipes are identical: 6.35 mm liquid line and 9.52 mm gas line, at the outdoor unit as well as at both indoor units. The material is not included in the offer; the specialist company selects it based on the pipe run and installation situation.

How large and how heavy are the units?

The indoor units each measure 838 x 280 x 228 mm and weigh 8.5 kg. The outdoor unit measures 800 x 550 x 285 mm and weighs 32 kg; it can easily be mounted on a wall bracket, and the specialist company assesses the load-bearing capacity on site.

How loud is the system?

This page lists 22 dB(A) for the indoor units on the low setting and 36 dB(A) on the high setting, as a specification for both; we will provide the intermediate settings and the values for each unit upon request. The outdoor unit is specified with 44 to 50 dB(A), depending on the operating point. The page does not state a sound power level.

How far apart can the indoor and outdoor units be located?

This page states neither the permitted pipe length nor the permitted height difference; we will provide both values upon request. Two pipe runs need to be planned, both from the installation location of the outdoor unit.

Can I use the system for heating in winter?

The outdoor unit has a specified range of minus 15 to plus 46 °C, without a distinction between heating and cooling; we will provide the separate limits upon request. In heating mode, class A+ applies on the A+++ to D scale with an SCOP of 4.3. The outdoor unit heats with 4.3 kW, the indoor units with 3.15 and 3.6 kW, so each heats more than it cools. The manufacturer specifies heat pump operation with a powerful start-up. Whether this is sufficient as the sole heating source, we can check upon request.

Can I install the air conditioner myself?

A certified specialist company carries out the installation and commissioning; self-installation is not intended. Two pipe runs and a 32 kg outdoor unit need to be planned.
