Linear with Stop
– In the input signal range from 20 to 100 %, the setpoint is
influenced linearly.
If the input signal is below 10 %, the pump changes to
operating mode Stop. If the input signal is above 15 %, the
operating mode is changed back to Normal. See fig. 49.

The setpoint is influenced by a curve made out of two to eight
points. There will be a straight line between the points and a
horizontal line before the first point and after the last point.
