Special features and expansions

The block diagram shows how you can interconnect the
pump controls and the solenoid valve. The layout
corresponds with the circuit diagram. You also have the
option to integrate further functions for specific applications,
which can only be implemented in a conventional circuitry by
adding further switchgear, e.g.:
• Enabling the pump at specific times
• Indication of imminent or existing water shortage
• Reporting of system faults
