Easy Installation

A simplified installation procedure allows the installer to work more efficiently, enabling quicker installation and greater customer service, especially during the peak season.

PID 0.5°C

Optimises the operating frequency before reaching the desired temperature and then constantly makes real-time adjustments to keep the ambient air temperature at the desired temperature.

Pipe lenght 300m/400m

Total pipe length is up to 300m (single fan), 400m (double fan) for complete installation flexibility.

Power Range 4 - 12 HP

Power Range 4 - 12 HP

R32

R32 is a type of refrigerant gas commonly used in air conditioning systems. It is a hydrofluorocarbon (HFC) with a low global warming potential (GWP) and is considered a more environmentally friendly alternative to older refrigerants.

Additional Information

Integrating Safety with Precision

The MRV7 S is engineered with a multi-zone leak detection system, providing comprehensive safety through built-in leak detectors in all our indoor units. The system incorporates visual and audible alarms within the new controllers. For added flexibility, an optional automatic shut-off valve can be installed, supported by a battery-powered emergency function, which is especially useful during power outages. This feature also allows for zone segregation, enabling the valve to isolate refrigerant and prevent leaks. These advanced safety protocols are built-in to proactively manage and reduce risks throughout the product’s lifecycle, from its initial design to its day-to-day operation, fully compliant with the new EU regulation 573/2024.

Multi-zone leak detection system

Integrating Installation and Control Flexibility

To further enhance efficiency, the MRV7 S features automatic addressing functionality. This simplifies the commissioning process by automatically assigning unique addresses to each indoor unit, eliminating the need for manual configuration. This is particularly advantageous for larger VRF systems with numerous 
indoor units, making both installation and commissioning processes more efficient and user-friendly. The new R32 MRV indoor units are all backward compatible with R410A refrigerant, reducing complexity from logistics to installation.

Automatic addressing functionality

Diamond Shield - R32 Safety Protection

  • Software: new version of the MRV selection software calculates the amount of refrigerant in the room and alerts if the safety limit is exceeded.
  • Alarm: the wired controller, panel and wall-mounted refrigerant detector can trigger a sound and light alarm in the case of a refrigerant leak.
  • Battery: SVP160A are equipped with a back-up battery, in order to supply power to close the shut off valves in the event of a system power failure.
  • Leak Detectors: Indoor units are equipped with built in leak detectors. There is no need to replace them after detection.
  • Recovery: In the case of a leakage, the system can recover the R32 refrigerant to the ODU and will be isolated by the shut off valves (single fan ODU). Unaffected units with SVP160A will continue operation, providing comfortable temperature to the user.
  • Shut off valve: the 4/5/6 HP MRV7 S outdoor units are equipped with built-in R32 shut off valves.
  • For the 8/10/12 HP MRV7 S outdoor units, an optional external shut off valve box (SVP160A) can be installed wherever it is necessary.
