Functional description
Each weekly timer has three cams you can use to configure a time hysteresis. You specify
the on- and off-times at the Cam parameters. The weekly timer sets the output at a certain
on-time, if this is not already set.
The weekly timer resets the output at a certain off-time if you configured an off-time, or at the
end of the cycle if you specified a pulse output. You will cause a conflict if the on- and off-
times you set for the weekly timer are identical, though set on different cams. In this case,
cam3 takes priority over cam2, whereas cam2 takes priority over cam1.
The switching state of the weekly timer is determined by the status of all three cams.
