The pump cleaning function is carried out with the starting and
ramp-down parameters of parameter set 1.
Parameter set 2
The pump cleaning function is carried out with the starting and
ramp-down parameters of parameter set 2.
Parameter set 3
The pump cleaning function is carried out with the starting and
ramp-down parameters of parameter set 3.
Operating parameters
(factory setting)
The pump cleaning function is carried out with the starting and
ramp-down parameters of the currently selected parameter set.
