ViCare app

The ViCare app provides the best way to connect you with your Viessmann heating system

With the new ViCare app, operating your heating system has become even easier and more intuitive. You can adjust heating times to suit your individual requirements using the integral wizard. Cost savings are also displayed instantly.

You will be able to see at a glance whether everything is working as it should be whilst operating the heating system. And if they are not, you will be notified automatically. With the ability to enter your contractor's details into the app directly, time will be saved when the need arises, as the contractor has all the information about your system to hand and can quickly provide support.


Downloading and using the app

The ViCare app is available for both iOS devices and Android devices. It can be used in
conjunction with a web-enabled Viessmann heating system, or in conjunction with the Vitoconnect 100 WiFi module, which can be obtained from your heating contractor.

Once connection and registration with your WiFi network has been established, simply scan the supplied QR code using a smartphone. The three LEDs visually interpret data communication and indicate the system status.
