Install Instructions

9.2.1 External input
This pump allows connecting external input as an additional
condition to the pump operation.
External input may be beneficial in the following situations:
• level switch in roof tank filling to stop the pump when the tank is
full
• inlet pressure switch to stop the pump in case of raised inlet
pressure
• moisture detection switch in irrigation applications to run the
pump only when the ground is dry.
External input must be 24 V digital input and can be connected
through the opening on the pump body. The cable length is limited
to 30 m.
External input can only be set up with Grundfos GO
Remote.
