The AC manufacturer function block, Astronomic clock, can be used to program

switching operations based on sunrise and sunset times. In order for this to work

properly, the settings for the device clock and the device location's time zone and

geographic coordinates must be correctly selected in this tab.

easyE4 base devices provide 32 weekly timer HW01...HW32

Each weekly timer provides 4 channels. These channels all

act jointly on the function block output Q1 of the weekly timer.

each be configured with an ON event and an OFF event in the parameter con-

figuration for the block. All channels act jointly on function block output Q1.

The following abbreviations are used for the individual days of the week:

Monday = Mon, Tuesday = Tue, Wednesday = Wed, Thursday = Thu, Fri = Fri,
