Each time period can be assigned to multiple timers; likewise, a timer can be
controlled by multiple time periods.
The figure below presents how different time periods are active in daily and weekly
modes.
A “boost” function is also available for the activation of the timers: a signal source can
be selected to extend the activation time for a parameter-adjustable time period.
