Summer- / wintertime changeover

Automatic changeover of the yearly clock to wintertime.
In accordance with present international standards, the change from summertime to
wintertime takes place on the last Sunday in October. The standard setting of the
controller complies with this rule since that Sunday lies between the standard setting
and the last day of the relevant month. With this setting, the day of changeover can be
matched to changing standards.
On the Sunday following that date, the controller's time of day will switch over to
wintertime.
For that purpose, the time of day is shifted backward by one hour.
Setting range
01.01...31.12.
