The highest feeling of comfort

NEXUS M EVI heat pumps enable optimal room temperature with minimal energy consumption. They allow the right air temperature to be achieved while providing access to hot water to fully meet consumer needs.

Advantages of the monoblock design

The pump is designed entirely for outdoor installation. A distinctive feature of the pump is that the entire cooling system is housed in a single unit, and only the pipes that supply heat to the building are routed outside.

Work under extreme conditions

NEXUS heat pumps are innovative system solutions from SUNEX that keep your home warm even in extremely low temperatures down to -25 degrees Celsius. They offer exceptional efficiency, reliability, and cost-effectiveness in operation.

Insyg Cloud + Antenna

The Insyg Cloud control module gives the manufacturer remote access to your heat pump. Sunex handles the complete configuration and maintenance of your heat pump.

The Insyg Cloud is used to operate the heat pump of the Sunex M EVI. It also controls two heating circuits and the hot water circuit.
Device is equipped with a color touch panel.

The device can be connected to:

• 2 circulation pumps
• 2 mixing valves (opening and closing)
• Electric heating element
• changeover valve
• Circulation pump

The heating circuits are controlled based on the set temperature of the heating circuit
(Sensors for circuits 1 and 2) and the room sensor or room thermostats (On/Off type).

Advantages of the Insyg Cloud:

• fast response time
• Touchscreen control panel.
  Control of heating circuits
• Management of heat generation for the hot water tank and the buffer tank
• Management of cooling generation for the buffer storage
• It is intended for the NEXUS pumps M EVI
