Two MSZ-HR25VFK indoor units, each with 2.5 kW, connected to one MXZ-2HA40VF outdoor unit with 4.0 kW cooling and 4.3 kW heating capacity—a Mitsubishi Electric multi-split set for two rooms. The Wi-Fi interface is built into both indoor units; no additional module is required for app control. The energy efficiency classes are 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. As a guideline, each indoor unit is suitable for a room measuring approximately 19 to 25 m²^*.

Performance and range of use

The Mitsubishi Electric MXZ-2HA40VF outdoor unit has a cooling capacity of 4.0 kW and a heating capacity of 4.3 kW, while each MSZ-HR25VFK indoor unit has a cooling capacity of 2.5 kW and a heating capacity of 3.15 kW. The combined capacity of the indoor units is 5.0 kW, which is 1.0 kW above the capacity of the outdoor unit. The operating temperature range of the outdoor unit is specified as -15 to +46 °C. Both indoor units have 6.35 mm liquid and 9.52 mm gas connections, and the outdoor unit has connections with the same dimensions at its two ports.

The stated area of approximately 19 to 25 m²^* applies to each indoor unit and is a guideline based on standard room height and standard insulation; it is not a binding design. Room height, insulation standard, window area, shading, and the number of people and devices are the decisive factors. We can assess 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, standard insulation, and average sunlight exposure. 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 based on the specific property. For a professional design of your property, please contact us.

Detailed functions

Built-in Wi-Fi

Yes. Both MSZ-HR25VFK indoor units come with a built-in Wi-Fi interface; no separate module is available for purchase for this set because none is required. The K suffix in the model code indicates this version. The manufacturer's app for this is not stated on this page, but we can provide that information upon request. Two remote controls are included.

Permissible configuration

The MXZ-2HA40VF outdoor unit has two ports, both of which are used in this set. The manufacturer states that the largest permissible configuration for this outdoor unit consists of two indoor units with 2.5 and 3.5 kW capacities. This set with two 2.5 kW units therefore falls within the permissible range, and if one of the two rooms is larger, you can choose a 3.5 kW unit instead of a 2.5 kW unit; please let us know before ordering. This outdoor unit cannot support a third room; we offer sets with three ports for that purpose.

Multi-split principle

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

Operating modes and airflow

• Cooling, heating, dehumidification, ventilation
• Four fan speeds and an automatic setting
• Vertical swing: the air outlet flap moves up and down
• Powerful startup, followed by maintenance of the set temperature
• Operating range of the outdoor unit from -15 to +46 °C

Control

• Two remote controls included, one for each indoor unit
• Wi-Fi interface in each indoor unit, app control
• Inverter technology in the outdoor unit

Frequently asked questions

What is the cooling and heating capacity of the set?

The MXZ-2HA40VF outdoor unit has a cooling capacity of 4.0 kW and a heating capacity of 4.3 kW, while each MSZ-HR25VFK indoor unit has a cooling capacity of 2.5 kW and a heating capacity of 3.15 kW. The energy efficiency classes are 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.

Which indoor units can I connect to this outdoor unit?

The MXZ-2HA40VF outdoor unit has two ports, both of which are used in this set. The manufacturer states that the largest permissible configuration for this outdoor unit consists of two indoor units with 2.5 and 3.5 kW capacities. This set with two 2.5 kW units therefore falls within the permissible range, and if one of the two rooms is larger, you can choose a 3.5 kW unit instead of a 2.5 kW unit; please let us know before ordering. This outdoor unit cannot support a third room; we offer sets with three ports for that purpose.

Can I control the system with an app?

Yes. Both MSZ-HR25VFK indoor units come with a built-in Wi-Fi interface; no separate module is available for purchase for this set because none is required. The K suffix in the model code indicates this version. The manufacturer's app for this is not stated on this page, but we can provide that information upon request. Two remote controls are included.

What operating modes does the system have?

Cooling, heating, dehumidification, and ventilation—four in total. 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 an 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 single outdoor unit. Each room has its own remote control and its own set temperature.

What happens when both indoor units run at the same time?

The two indoor units have a combined capacity of 5.0 kW, while the outdoor unit is rated at 4.0 kW. This is a difference of one kilowatt, which is small enough that both rooms can be brought to temperature at the same time; each indoor unit then receives approximately four-fifths of its rated capacity. If only one runs, it has the full 4.0 kW to itself. This set is therefore also suitable for two rooms being used simultaneously, not just for alternating use.

Which rooms is this set suitable for?

According to the manufacturer, each indoor unit is designed for approximately 19 to 25 m²^*. Two identical indoor units are suitable for two similarly sized rooms: a living room and bedroom in a smaller apartment, two children's rooms, or two offices. At 21 dB(A) on the lowest setting, there is no reason it would not be suitable for a bedroom. We assess the binding design based on the specific property.

How many indoor units are included in the delivery?

Two, both MSZ-HR25VFK with 2.5 kW each, plus two remote controls and the MXZ-2HA40VF outdoor unit. Pipes, installation materials, and the bracket or console for the outdoor unit are not included in the delivery.

Is an installation set required for each indoor unit?

Yes, two, and they are identical: 6.35 mm liquid and 9.52 mm gas lines, at both indoor units as well as at both ports of the outdoor unit. The material itself is not included in the offer; the qualified company selects it based on the pipe run and installation situation.

How large and 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 qualified company assesses the load-bearing capacity on site.

How loud is the system?

The indoor units are rated at 21 dB(A) on the low setting and 37 dB(A) on the high setting; this page does not state what lies in between, but we can provide that information upon request. The outdoor unit is rated at 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 does not state the permissible pipe length or the permissible height difference; we can provide both values upon request. Two pipe runs must be planned, both from the installation location of the outdoor unit.

Can I use the system for heating in winter?

The manufacturer states an operating range of -15 to +46 °C for the outdoor unit, without separately specifying heating and cooling; we can provide the separate limits upon request. The system operates as a heat pump and starts at high capacity after switching on, then switches to maintaining the temperature. In heating mode, it has an A+ rating on the A+++ to D scale with an SCOP of 4.3; the outdoor unit heats with 4.3 kW, and each indoor unit with 3.15 kW, so each heats more than it cools. Whether this is sufficient as the sole heating source for your rooms, we can assess upon request.

Can I install the air conditioner myself?

A certified qualified 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.
