A separate view with the necessary variable switches must be available for
every used time switch. The views for the different time switches are called
from an overview display.
In this case the summer/winter time changeover is controlled by the radio
clock module. You can change this default setting via the push of the
corresponding button in the ProTool view. Thus the changeover will be
performed program controlled with the FB 103 „summer_winter".
