Due day values are transmitted every 4 hours.
The due day values are transmitted on the third day of the month between 5 am
and 10 pm.
Please note the following for the Web Server at the conclusion of the comments
under "Due day formation":
· The temporary due day value and its dates is written to the due day field for in
the consumption data file if the QAX9... has not yet achieved a due day by the
first transmission to the Web Server.
· At the latest then, the first real due day value with due date is available on the
QAX9... 12 months after commissioning and is written at the start of the next
month (third day) to the field due day of the consumption data file.
· A due day value is still available on the Web Server on the third day of the
month if the due day is set to the first day of a month.
· Synco 700 controllers do not support the due day function.
· The OZW772... do not have an S-Mode input for due date.

replacement. The information is provided to the Web Server accordingly.
· A new generation of the device web pages after a device exchange of QAX9...
or Synco 700 controller always results in a meter replacement even when the
same meter is re-connected to the replacement device.
· Hiding a device in the device list also results in a meter replacement.
Changes to the following information are interpreted as a meter replacement:
· Meter medium
· Meter ID number
The following changes are also evaluated for pulse meters:
· Unit factor (e.g. from "10 Wh" to "100 Wh")
· Pulse value (counter or denominator)
· Start value
Changes to the following information are interpreted as a meter replacement:
· Unit
· Format (number of decimal places)
