Relevant Parameter Setting
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).
