Important

Specifications and features may vary by model and configuration. All performance figures are subject to system design, installation conditions and operating parameters.
For the indoor units, a Basic or Comfort pre-plumbing jig must be added to the order; see Accessories tab.
The heat pumps must be commissioned by Viessmann Technical Service or a specialist heat pump contractor trained by Viessmann.
To operate multiple regulated heating/cooling circuits downstream of the heating water buffer cylinder, a separate heating/cooling water buffer cylinder is required.
Extensions/accessories are required for the heating/cooling circuits with mixer and optimisation of self-consumption: see Accessories tab.

Viessmann Energy Management

Viessmann Energy Management is integrated in all heat pumps and in photovoltaic inverters/power storage systems with Viessmann One Base.
Energy Management allows balanced operation of components in the home which generate, consume or store electricity.
Its focus is on self-consumption optimisation of self-generated power from photovoltaic systems.
The energy management system provides extensive information on electricity flows and CO2 reduction
Viessmann Energy Management turns a heat pump with Viessmann One Base into a control centre for the energy flows in the home.
The energy flows between photovoltaics, heat pump, energy store, wallbox and other compatible accessories are optimised.
On request, customers can add further optimisation stages in the ViCare app.

For further information on system requirements, functions and use see Viessmann Energy Management and Viessmann One Base
