Vitoconnect Type OPTO1

The Vitoconnect Wifi interface establishes a connection between the heating system and the Viessmann mobile app, to allow for operation of the heating system, as well as remote maintenance via the Vitoguide service app. In the Vitoconnect infrastructure, a comprehensive safety concept was implemented, which successfully passed tests for home information security from the VDE Institute, an internationally accredited testing and certification institute for electrotechnical devices, components and systems.
