Hallo,

No.
First of all we choose a basic speed "Max. speed".
Then we measure the flow rate of the pump and we indicate it in the box "Max. flow (determined by calibration)", it is this box which determines the calibration.
Finally, the desired flow rate is selected in "Desired flow (xx ... yy)". xx ... yy indicates the possible interval. This does not affect the calibration, it allows you to set a precise flow rate.
