10.4 List of special days
There are two lists of special days in the meter. One list is composed of permanent special days
(the same date each year) and the other list contains leap-special-days (different date each year).
Both lists in total may contain up to 128 special days. Meter LCD displays all special days,
furthermore, they may be reviewed in a computer when meter parameters are read via
communication interface.
When a new day begins, the meter addresses to the special days list and checks whether that day
is in that list. If the day is specified in either special day list, the tariff module activates day profile
for special day.
