Vitoguide – the centre for innovative digital services

Viessmann is now offering its trade partners an innovative solution for monitoring heating systems with Vitoguide software. The system user benefits from greater reassurance, whilst the trade partner keeps a constant watch over the heating systems for which they are responsible online.

Important changes for Vitoguide: Further information can be found below in the "Mobile" section below.


On April 1st 2021, the ViStart mobile app became Vitoguide.  The Vitoguide mobile app is available on both iOS and Android devices. As a partner, it will continue to offer you the option of putting a new electronic platform heating system into operation.

The Commissioning Process

Putting a new heating system into operation simply, quickly and safely – Vitoguide app makes it easy. The tool for your smartphone makes commissioning easier for you, considerably reduces the time it takes to hand it over to the system operator and can be used practically without prior experience.

The app guides you through the commissioning procedure in four steps:

  • Select the boiler to be commissioned from the list, the app automatically establishes a direct connection to the unit. With the integrated WiFi access point, no internet connection is required.
  • After entering the network name and a password, the user-friendly dashboard appears. For verification purposes, the Vitoguide app serial number of the boiler is displayed and confirmed with “Continue”.
  • All parameters are then consecutively queried and set, e.g. system pressure, heating curves, naming of heating circuits and time programs.
  • The device is running. Finally, an acceptance report with all settings can be generated. This can be sent for your own records or to the customer.
