Munro Startbox - Pressure Start Control Box

StartBox – On Demand Controls

The Pressure Start Control Box is used to start a pump in response to system demand, without the need for a signal from an external device like an irrigation controller.

Any drop in the line pressure is detected by a pressure switch which activates the pump. When the system pressure rebuilds and is high enough to cut-out the pressure switch, a flow switch takes over monitoring the system. If flow is present, the pump will continue to run. When flow stops, a time delay is activated to reduce short-cycling of the pump. After the delay times out, the pump shuts down.

If a line leak drops the pressure low enough, the pump will come on for the amount of time set on the time delay; and then shut off. To ensure the pump doesn’t short-cycle, the time delay is set to approximately 1 minute.
