Winter/Summer Changeover
This menu is only visible when the automatically changeover of daylight saving is
enabled. Pressing SET lets the user edit the time/date of the changeover as described
in section "Time & Date" but there is one peculiarity:
Beginning and ending of daylight saving may either be defined by exact dates for a
single year or using an algorithm which allows the DU35K to recompute the effective
dates year by year.
The example beside shows how to enter the first case:
The day-of-week does not need to be specified and
therefore is displayed as wildcard (*). The time/date
of next years changeover has to be entered as well
(year by year).
In the second case the day-of-week must be specified. Then, starting from the confi-
gured date, daylight saving starts the first day whitch matches the configured day-of-
week.
The example shows what has to be entered when daylight
saving has to start the last sunday in march every year:
The year (**) does not need to be specified because the
changeover algorithm is valid for all further years, too.
Summer/Winter Changeover
The Summer/Winter menu appears after ending the Winter/Summer menu by
pressing MENU and is to be edited as well.
The example beside shows how to enter a fixed
time/date for a singe years daylight saving end:
The time/date of next years changeover has to
be entered as well (year by year).
When daylight saving has to end the last sunday in
october every year the following has to be entered:
(day-of-week: 1 = monday, 7 = sunday).
Exit
Pressing SET in this menu lets the DU35K change over from the 'set parameters'
mode into the normal operation mode. All changes of parameters are valid now.
