Rainwater Pump with FL1A-H10RCB
Apart from IDEC SmartRelay, 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.
