Apart from LOGO!, you only need the pressure switch and
the float switches to control the pump. If you are using a
3-phase AC motor, you must use a master contactor for
switching the pump. On systems using single-phase AC
pumps, you must fit a contactor if the AC pump requires a
higher current than can be switched by the output relay Q1.
The power of a solenoid valve is so low that it can normally
be controlled directly.
