12.7 Real-time clock

The real-time clock of the control is buffered in the switched-off state. The buf-
fer capacitor looses efficiency when operated permanently at high tempera-
tures. The buffer time of the real-time clock depends on the ambient tempera-
ture and the operating time of the control.
