User registration via the ViCare app and configuration of the Vitoconnect

The next and central step is user registration, as the Vitoconnect can only be commissioned with a valid user account. For the ViCare app, do this as follows:

1. Download the ViCare app.
2. Tap "Create new account" to create your user account.
3. Scan the QR code on your heat generator or invoice.
4. If no code is available, enter the manufacturing data and ID and register.
5. On Android devices, the connection to the "Vitoconnect" WiFi is now established automatically.
6. If you are using iOS: Close the app and go to the device settings. Then manually establish a connection with the "Vitoconnect" WiFi and paste the WPA2 password from the clipboard. Now switch back to the app.
7. Finally, follow the instructions in the app to set up a home network, enter your location and personal data, and accept the privacy policy and terms of use.

Vitoconnect and the ViCare app are now set up and ready for use. This is also indicated by the two upper green LEDs on the Vitoconnect.

You also have the option of registering only your new system. We will then extend your warranty and confirm this with a system certificate. This also contains all the data for your system. If you have already established a connection with the ViCare app, you can use the information given there.

The full range of functions of the Vitoconnect is only available if both the Vitoconnect itself and the control unit are correctly connected and configured. Furthermore, a permanent internet connection via a WiFi router must be available. Otherwise, the data cannot be transmitted from the heating controller to the app. Last but not least, a user account must have been set up. This links the Vitoconnect to the system's account (in the app).

General information on commissioning:

• Before commissioning, check the system requirements for communication via the local IP / WiFi network.
• For operating the Vitoconnect, an available internet connection with flat rate data (no time or volume restrictions) is required. The WiFi signal must be sufficiently strong and can be amplified using a repeater if necessary.
• To ensure that messages can still be sent if there is a power failure, we recommend connecting the Vitoconnect and WiFi router to the power supply via an uninterruptible power supply (UPS).
• The WiFi router should be protected by a sufficiently strong WPA2 password, as sensitive data is transmitted via the connection.
• The Vitoconnect should be installed at a distance of at least 0.3  metres from the heat generator.

Firewall settings:

• Port 443 (HTTPS) and port  123 (NTP) must be open.
• The MAC address is printed on the device label.
