The communication box connects to
the server under the following condi-
tions:
- Every 2 weeks to transfer the latest
status data of the appliances. The
connection time is around 30 seconds
per connected appliance. You can
deactivate this on the internet but it
restricts the functions of the vrnet-
DIALOG.
- For 60 seconds in the event of a
malfunction.
If the server connects to the device
via telephone, the telephone in the
house may ring if there is no tele-
phone system or separate telephone
connection.
Please tell your customer about this.
