Low pressure running time should be increased for
use-cases where water pressure rises slowly. The LP
running time b01.02 determines the maximum time
that pressure is below cut-in pressure. Controller stops
and alarms when the pressure below cut-in pressure
lasts for a duration three times of the setting b01.02.

This example uses the pressure switch for control instead of the transducer (Wiring refer
to figure 1). Adjustment of the pressure switch cut-in and cut-out pressures should be
done before running. For example for 3bar water supply, then up contact adjust above
3bar (such as at 3bar), bottom electric contact below 3bar (such as at 2.8bar).
