ViCare App

Stay connected with your Viessmann boiler

The new ViCare app makes the operation of your Viessmann boiler easy and intuitive. With the built-in wizard, you can easily monitor and program your boiler, set the desired temperature in up to 3 heating circuits in your home for multiple times throughout the day and week, and stay connected and in control anywhere you have access to the Internet. You can also see your potential energy savings on a summary page.

Peace of mind at your fingertips

ViCare provides instant feedback and alerts about changes in the status of your Viessmann boiler. You can see at a glance whether everything is working as it should, and if not, you will be notified automatically. You can also enter your contractor's contact information directly into the app. Finally, you have the option of having your contractor monitor your boiler remotely via the specially developed Vitoguide software.

ViCare app


The ViCare app is available for iOS and Android mobile devices, and can be downloaded for free from the Apple App Store and Google Play.

Vitoconnect Wi-Fi module

The Vitoconnect wall-mounted Wi-Fi unit is the interface between the ViCare app and the Viessmann boiler. It connects directly to the boiler control with a cable, and it communicates over the Internet via the local Wi-Fi network.

After the ViCare app and Vitoconnect have been set up, you can operate the boiler and see its status at a glance on your smartphone.

ViCare can also control Viessmann heating systems that have already been installed. Most Viessmann boilers and Vitotronic controls equipped with an Optolink interface can now be operated anytime, anywhere using the ViCare app and Vitoconnect.
