The following parameters must be configured:
24-hour activation function
Pumps with long downtimes can be activated cyclically with the 24-hour activation function
for the time defined in Sw. period (0-999 seconds).
The starting time for the 24-hour step interval can be postponed by 0 to 23 hours with the
Sw. delay setting.
