5.3.5 The "flush control" submenu
The flush control is used to switch a pump on for a number of cycles (flush cycles) for a defined time
(flush time). This switching-on takes place within the defined number of pump cycles. The figure
below shows an example with 5 pump cycles and 2 flush cycles. The last two of the five pump cycles
are used for flushing.
A pump cycle always starts with the first pump being switched on and ends if all pumps are switched
off again.
