Midea Mars Large Mono R290 70kW monoblock heat pump MHS-SVC70-RN7TL-B A+++/A+++

The Mars Large Series, powered by R290 refrigerant and all-DC inverter technology, offers a reliable year-round solution: it can heat, cool, and provide hot water up to 85°C. The system can also be used as a hybrid system to work with various heat sources.

With an output of 60 or 70 kW, the heat pumps from the Mars series are very powerful. For larger buildings, up to six units can be cascaded to meet demand.

The included controller with color display won a Red Dot Award for its attractive design. Operation is simple and straightforward, allowing you to easily access all functions. You can also connect the unit to the Midea SmartHome app, allowing you to control it from anywhere.

Commercial buildings often require different temperatures in different areas—for example, in shopping malls, offices, or when hot water is needed. The Mars series is equipped with a dual-zone control system that allows for two independent water outlet temperatures to be set. This ensures greater comfort and flexibility.

Here are some important performance data:

Up to 85°C water at -15°C outside temperature
Up to 80°C water at -20°C outside temperature

The series therefore covers most European heating scenarios and is therefore very versatile.

The heat pump is Smart Grid Ready.

This means it can be integrated into smart grids. When there's excess energy in the grid, the pump can automatically work harder to store water, contributing to grid stability.

Further highlights:

All-in-one system:

The refrigeration and hydraulic systems are integrated in the outdoor unit.
Hermetic construction: The refrigeration circuit is hermetically sealed, which increases safety.

Easy installation:

Thanks to the integrated monostructure, the water pipes are clearly visible and installation is straightforward.

System security design:

The system is designed to eliminate any refrigerant or ignition hazards. Sensors continuously monitor temperature and pressure to ensure safe operation.

Efficient plate heat exchanger:

Multi-plate heat exchangers ensure high heat transfer with minimal losses.

Reliability:

Explosion-proof components, anti-freeze software and special designs protect against ice formation and ensure safe operation.

Environmentally friendly refrigerant:

R290 (propane) has no ozone-depleting effect and a very low GWP, which is environmentally friendly.

Freeze protection:

The system heats water when needed to prevent frost damage.

Hot water function:

With “Fast DHW” you can provide hot water quickly, and the “DHW Pump” function ensures that it is returned to the storage tank.

User-friendly controls:

The controller with color display and the SmartHome app enable easy operation and remote control.
Quiet operation: Both the heat pump and the water pump run as quietly as possible.

Disinfection function:

Legionella bacteria are killed with 70°C hot water to ensure water quality.

Automatic temperature adjustment with climate curves

This function ensures that the water temperature is automatically adjusted to the outside temperature. 32 standard climate curves, pre-set by an experienced engineer, ensure optimal control. In addition, customized curves can be created to meet specific requirements.

Vacation modes

While you're away on vacation, the heat pump continues to run in heating mode with a low water temperature to protect the water system from freezing and prevent mold growth. When you're home on vacation, you can use the "Holiday Away" function to adjust the schedule for that time—without changing your regular daily or weekly settings.

Energy recording

The integrated energy measurement function can calculate the proportion of renewable energy used by the system. You can receive customized energy analyses via a user interface, an app, or a web portal. The core algorithm calculates the compressor's performance.

Easy to use

The control unit is permanently installed and features a robust glass panel with a metallic frame and a 3.5-inch color display. It offers a clear and intuitive user interface, even in standby mode.

Communication and control

The control unit can be connected to the home bus via a 2-wire, non-polar cable. It also supports the Modbus protocol, has an OTA function for remote updates, and is equipped with Wi-Fi. With the practical SmartHome app, you can monitor and control the heat pump anytime, anywhere.

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.
