Operation via app
ViCare app
You can control your heating system remotely via the
internet using an app.
Vitoguide
For contractors only
Your heating system can be remotely monitored by
your contractor. For this, your contractor requires serv-
ice clearance.
Forwarding messages
Any pending messages from the heating system, e.g.
sensor or burner faults, are transmitted to the
Vitoconnect 100 via the Optolink cable. The
Vitoconnect 100 transmits these messages to the
Viessmann server. The ViCare app regularly checks
the status of the heating system and displays any mes-
sages.
Note
Heating system messages are only displayed if the
ViCare app is active on the mobile device.
