Digital Tools from Viessmann

Viessmann’s new digital ecosystem includes an improved ViCare app for homeowners and Vitoguide tool for installing contractors.  


Vitoguide is Viessmann’s revolutionary, time-saving digital application for heating professionals that allows installing contractors to commission the new Vitodens boilers right from their mobile device, eliminating a number of manual processes and saving valuable time on the job site. With Vitoguide, an installing contractor can choose the boiler control language, automatically change the fuel and altitude settings, and even fill the boiler with just the press of a button, among other functions. After installation, Vitoguide will enable contractors (with the homeowner’s permission) to remotely monitor and service the connected boilers, stay in touch with their customers, and receive service alerts and/or scheduled maintenance reminders.


For homeowners, Viessmann offers ViCare: a unique, all-in-one solution that allows users to control their heating system via any connected mobile device. With a simple user interface, ViCare makes operation intuitive and accessible on demand. The app-based tool provides instant feedback and alerts about changes in the status of the connected Viessmann boiler. Users can see at a glance whether everything is functioning properly, is due for routine maintenance, or needs service. Fuel use and savings are also tracked and displayed in a user-friendly way to monitor the system owner’s return on investment year after year.
