Introducing the Munro Startbox MPSR220AYF – with ON DEMAND Instantaneous Control Solution

The Pressure Start Control Box operates as a pump that responds to the demands of your system, eliminating the necessity for a signal from an external device such as an irrigation controller.

Any decrease in the pressure within the pipeline is identified by a pressure switch, which then triggers the activation of the pump. Once the system pressure is restored to a level sufficient to deactivate the pressure switch, a flow switch takes over the role of monitoring the system. As long as there is a flow present, the pump will remain operational. When the flow ceases, a predefined time delay is initiated to prevent the pump from rapidly cycling on and off. After this delay period elapses, the pump will be deactivated.

In cases where a drop in pressure is caused by a line leak, the pump will activate for the duration specified by the time delay setting before automatically turning off. To prevent undesirable short-cycling of the pump, the time delay is typically calibrated to around 1 minute.
