  1. Install the Viessmann ViCare app on your smartphone or tablet (available for iOS and Android).

  2. Locate the individual QR code for securely connecting your heater to your wireless network (WLAN router). Your heating engineer has affixed this sticker to the heater in a place that is accessible to you: either directly on the housing of your heater or in the technical documents included with your heater. If you cannot find this sticker, please contact your heating engineer who installed your Viessmann heater.

  3. Follow the instructions in the commissioning menu of the ViCare app. During commissioning, you will scan the QR code and use it to connect your heater to your wireless network (WLAN router).
