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

The Mars Large series, with 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 to work with various heat sources.

With a power output of 60 or 70 kW, the Mars series heat pumps are very powerful. Up to six units can be cascaded to meet the demand in larger buildings.

The included control unit with color display has received the Red Dot Award for its appealing design. Its operation is simple and intuitive, allowing you to easily use all functions. You can also connect the unit to the Midea SmartHome app and control it from anywhere.

In commercial buildings, different temperatures are often required in various areas – for example, in shopping malls, offices, or for hot water needs. The Mars series is equipped with dual-zone control, allowing you to set two independent water outlet temperatures. This ensures greater comfort and flexibility.

Here are some key performance data:

Water up to 85°C at -15°C outside temperature
Water up to 80°C at -20°C outside temperature

This means the series 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 is excess energy in the grid, the pump can automatically work more to store water, thus contributing to the stability of the power grid.

Other highlights:

All-in-one system:

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

Easy installation:

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

System security design:

The system is designed to eliminate any risk from refrigerants or ignition. Sensors constantly 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, frost protection 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 protects the environment.

Freeze protection:

The system heats water as needed to prevent frost damage.

Hot water function:

With "Fast DHW" you can quickly provide hot water, and the "DHW Pump" function ensures the return 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 operate as quietly as possible.

Disinfection function:

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

Automatic temperature setting with climate curves

This function ensures that the water temperature is automatically adjusted to the outside temperature. 32 standard climate curves, pre-configured by an experienced engineer, guarantee optimal control. In addition, individual, customer-specific 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. If you're at home on vacation, you can use the "Holiday Away" function to adjust the schedule for that period – without changing the 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 obtain individual energy analyses via a user interface, an app, or a web portal. The core algorithm calculates the compressor's power consumption.

Easy to use

The control unit is permanently installed and features a robust glass panel with a metal 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 Homebus via a 2-wire, non-polarized cable. It also supports the Modbus protocol, has an OTA function for remote updates, and is equipped with Wi-Fi. With the convenient Smart Home app, you can monitor and control the heat pump anytime, from anywhere.

Important NOTE!

The installation and commissioning of the equipment must be carried out exclusively by qualified personnel. In the event of a complaint, proof of proper installation by qualified specialists (certificate of professional qualification and special qualifications) must be provided. If no such proof is provided, all warranties and guarantees will be void.

Technical specifications subject to change without notice. Errors and omissions excepted. Subject to prior sale. Image may differ from actual product.

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.
