SU-WI FREE SETTING
Here it is possible to stipulate your own changeover setting.

First the month for the summer-winter changeover is set.

This is followed by the setting for the summer-winter changeover (week 1 to 5). This
corresponds to the first, second, third, fourth or last week in the month (week 5 therefore always
refers to the last week in the month).

This is followed by weekdays 1 to 7, i.e. the weekday Monday to Sunday can be set. The set
weekday is valid both for the changeover from winter to summer time as well as for the
changeover from summer to winter time.

Finally, the selection of the hour for the winter / summer time changeover, i.e. the hour on which
the timer goes forward by one hour. The changeover from summer to winter time is carried out
on the same hour (it then goes back one hour later to this time). The setting range is from 00:00
midnight to 10:00 pm. 11:00 pm is blocked to ensure that when going back from summer time
to winter time that the time after the date change at 0:00 midnight does not have to go back to
the previous day to 11:00 pm.

To go back from summer to winter time only the month for the reset and the week in the month
(1 - 5) have to be set. The setting is then saved.
SU-WI FIXED DATE
In this case, two fixed dates can be entered (Month + Day + Changeover Hour), on which the
changeover is to be made from winter to summer time and vice versa each year.
