Midea M-Thermal Nature Mono MHC-V12WD2RN7-BER90 R290 monoblock heat pump 12kW A+++/A++

R290 M Thermal Nature Mono

Capacity: 8-16 kW

Flexible heating, cooling, and domestic hot water use with the M thermal Nature: With water temperatures up to 80°C, the heat pump enables a wide range of applications and is an ideal replacement for existing heating and hot water solutions. Thanks to the ability to combine up to six units with a capacity of 49-96 kW, the system is also suitable for large buildings. The cascade option with various heating sources also allows it to be used as a hybrid system.

All-in-One

Heating, cooling, sanitary hot water with up to 80°C hot water

Energy efficient

EU energy efficiency class A+++ at 55°C/35°C water temperature thanks to DC Inverter technology and natural refrigerant R290

System Safety Design

Electronic control unit as well as cooling and water system are protected against interference and external influences

One-Stop Solution

The M thermal Nature heat pump enables heating and cooling throughout the house and, thanks to the Midea Nature series, can be easily combined and controlled with other energy management components.

High efficiency

Thanks to DC inverter technology, the M thermal Nature heat pump achieves EU energy efficiency class A+++ at 55°C/35°C water temperature and combines ecological requirements with economic efficiency.

Thanks to the excellent thermodynamic properties of R290 and advanced heat pump technology, M thermal Nature delivers high performance even in cold conditions with only a small amount of R290. R290 is a high-purity propane with zero ozone depletion potential (ODP). Its low GWP underscores its environmentally friendly properties, supporting EU climate neutrality.

System security design

The safety design includes explosion protection for the circuitry and wiring, as well as a fully enclosed electrical control enclosure. The refrigerant and water systems feature anti-freeze detection in the plate heat exchanger, as well as separate maintenance access for the cooling and hydraulic systems.

Electric heater

An electric heater with a capacity of 3 or 9 kW is integrated directly into the heat pump. The electric heater ensures an independent power supply and serves as a backup heat source in the event of a heat pump failure. It also provides additional frost protection.

Highlight features

Antifreeze

When the temperature of the water flowing through the system drops to a certain value, the unit heats the water, either using the heat pump, the auxiliary heater, or the additional heating source. The anti-freeze function only deactivates when the temperature rises to a certain value.

Vacation mode

The "Holiday Away" function can be used to protect the device from frost damage while on vacation, depending on the current climate. When this function is activated, the device will run in heating or hot water mode at a lower set temperature for the set period.

Floor protection

For newly installed underfloor heating systems, the floor drying function helps remove moisture from the floor slab and subfloor, preventing warping or cracking of the floor. The preheat function ensures that the water pipes in the floor are slowly heated during the first use of the heating season, reducing the risk of damage to the floor and the piping system.

Defrost function

By monitoring the ambient temperature, heat exchanger temperature, water temperature and compressor running time, the heat pump can perform an intelligent defrost program to recover heating power and thus avoid heat loss due to unnecessary defrosting.

Powerful heating

60°C hot water down to -25°C outside temperature only with heat pump.
80°C hot water from -10°C to 15°C outside temperature only with heat pump.
80°C hot water from -25°C to 35°C outside temperature through heat pump with integrated electric heating.

Particularly quiet

Reducing the noise source volume by:
Optimization of the compressor components, the low-frequency pipe and the large, curved and very quiet axial fan
Optimized cable route
·Silent mode of the heat pump by lowering the compressor and fan frequency for quiet operation (2 levels)
Silent mode of the water pump, which adjusts the maximum internal water pump power to reduce the noise of the heat pump

Easy to use

The permanently installed control unit features an integrated tempered glass panel with a metallic frame and a 3.5-inch color display. It offers an immersive user interface with a standby mode. Homebus communication is possible via a 2-wire non-polar cable. The control unit also supports the Modbus protocol, has an OTA function for remote updates, and built-in Wi-Fi.

The operation of the heat pump can be monitored and controlled at any time and from anywhere using the practical SmartHome app.

Smart functions

Backup function

If some sensors fail, the intelligent algorithm uses the data collected from other sensors to create a virtual sensor simulation of the faulty sensors and simultaneously notifies maintenance so that the device can continue to run for a short time until maintenance is carried out.

Automatic temperature adjustment with climate curves

This function automatically regulates the water temperature depending on the outside temperature and room temperature. Eight preset standard climate curves and one custom curve cover common applications and meet diverse requirements.

Energy recording

The energy measurement function is capable of calculating the proportion of energy generated from renewable sources. End users have the option of receiving customized energy analyses via a user interface, an app, and a web portal. The core algorithm: calculating compressor performance.

Automatic switching between heat pump and additional heat source
Automatic switching between heat pump and additional heat source based on economic considerations (gas price, electricity price) and to achieve maximum system efficiency.

Important NOTE!

Installation and commissioning of the devices must be carried out exclusively by qualified personnel. In the event of a complaint, proof of proper installation by qualified specialists (certified contractors and special qualifications) must be provided. Failure to provide such proof will void any warranty and guarantee.

Refrigerant leaks contribute to climate change. Refrigerants with a lower global warming potential (GWP) contribute less to global warming in the event of a leak than those with a higher global warming potential (GWP). A leak of 1 kg of this refrigerant would therefore have a greater impact on global warming than 1 kg of CO2 over a 100-year period, proportional to the refrigerant's GWP value. Do not perform any work on the refrigerant circuit or disassemble the unit – always consult qualified personnel.
