Description of the function
Each weekly timer is equipped with three cams. You can configure a time hysteresis for each

over cam 2, while cam 2 takes priority over cam 1.
The switching status of the weekly timer is determined by the status at the No1, No2 and

The block properties window offers a tab for each one of the three cams. Here you can set
the day of the week for each cam. Each tab offers you in addition an option of defining the
