The Mitsubishi MSZ-HR35VFK cools and heats using inverter technology and can be controlled via an app. The indoor unit operates at 22 dB(A) on its lowest setting, making it discreet even in the bedroom. The inverter technology adjusts the output continuously between 0.9 and 3.4 kW, rather than constantly switching on and off. This reduces power consumption and maintains a constant room temperature. The power class is suitable as a guide for rooms measuring approximately 25 to 34 m²^*.

Performance and range

The unit belongs to the 3.5 kW class and delivers 3.4 kW of cooling and 3.6 kW of heating capacity. The cooling capacity corresponds to approximately 12,000 BTU. In cooling mode, the system operates at outdoor temperatures between minus 10 and plus 46 °C, and in heating mode between minus 10 and plus 24 °C.

The stated area of approximately 25 to 34 m²^* is a guideline based on standard room height and normal insulation standards, not a binding design specification. The correct power class for your property depends on room height, insulation standards, window areas, shading, and the number of people and devices. An undersized unit will run continuously at full load, while an oversized unit will cycle and consume electricity unnecessarily. 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 sunlight exposure. Different conditions on site, such as large window areas, sloped roofs, or a high number of occupants, may require a different power class. The binding design is determined on a property-specific basis. For a professional design of your property, please contact us.

Detailed functions

Inverter and heat pump operation

The inverter compressor adjusts its speed to the actual demand. At startup, the system runs at high power to quickly bring the room to the desired temperature. Then it reduces to the minimum required power of 0.9 kW and maintains the temperature without noticeable fluctuations. In heating mode, the unit operates as an air-to-air heat pump and utilizes the heat from the outdoor air down to minus 10 °C.

Operating modes

• Cooling: 3.4 kW nominal, adjustable from 0.9 to 3.4 kW
• Heating: 3.6 kW nominal, adjustable from 0.9 to 3.7 kW
• Dehumidification: reduces humidity without cooling the room significantly
• Ventilation: air circulation without cooling or heating operation

Control and comfort

The Wi-Fi module, sometimes also referred to as a WiFi module, is built into the indoor unit and does not need to be retrofitted. An infrared remote control is also included. You can set the vertical airflow direction using the remote control and the horizontal direction manually on the louvers.

• Three-stage airflow speed control (low, medium, high)
• Vertical swing for even air distribution

Operational safety

• Fault diagnosis system for quickly isolating malfunctions
• Automatic restart after a power failure with all saved settings

Frequently asked questions

What cooling and heating capacity does the MSZ-HR35VFK have?

The cooling capacity is 3.4 kW, and the heating capacity is 3.6 kW. Both values are continuously adjustable from 0.9 kW via the inverter. We can check which power class is suitable for your room upon request.

Is the installation kit included in the price?

The installation kit is an optional addition and is added via the variant selection. Without a selected installation kit, the delivery includes only the indoor unit, outdoor unit, and remote control. The kit is available in lengths of 3 to 12 meters.

Does the air conditioner have Wi-Fi, and do I need additional accessories?

No, additional accessories are not required. The Wi-Fi module, sometimes also referred to as a WiFi module, is already built into the MSZ-HR35VFK indoor unit. You only need a Wi-Fi network at the installation site.

How far apart can the indoor and outdoor units be?

The maximum pipe length is 20 m, and the maximum height difference between the indoor and outdoor units is 12 m. The optional installation kit is available in lengths of 3 to 12 m.

Can I use the unit for heating in winter?

The system heats using heat pump operation down to an outdoor temperature of minus 10 °C. It is suitable as a supplement during the transitional season. For continuous operation in severe frost, units from the Hyper Heating series are designed.

How loud is the unit?

Depending on the fan setting, the indoor unit operates between 22 and 46 dB(A) in cooling mode and between 21 and 44 dB(A) in heating mode. The manufacturer specifies 51 dB(A) for the outdoor unit.

Can I install the air conditioner myself?

The installation and commissioning of a split air conditioner are carried out by a certified company. Self-installation is not intended.
