Important Notes.

• Heat pumps must be commissioned by Viessmann Technical Service or a specialist heat pump contractor certified by Viessmann

• A hydraulic connection set must also be ordered to install the appliances; see "Accessories"

• If the heat pump is being installed to modernise a heating system, a dirt separator with magnet is essential; see "Accessories"

Energy management systems.

Viessmann energy management:

• Viessmann energy management is integrated into the latest generation of Viessmann heat pumps and energy storage units

• It enables balanced operation of the components in the house that generate, consume or store electricity.

• The focus is on optimising self-consumption of self-generated electricity from photovoltaic systems.

• The energy management system provides extended information about electricity flows and also CO2 savings.

• If desired, customers can add further optimisation levels in the ViCare app.
