ELECTRONIC PRESSURE REGULATOR FOR SINGLE PHASE PUMPS
This device controls start-up and shutdown of the pump on opening and closing of the valve. In the event of no flow on intake, the electronics block the pump, thereby protecting it from dry running. Once the cause of this flow failure has been eliminated, simply press the red Restart button (reset) to restore normal operating conditions. In the event of a temporary power failure, the unit restarts automatically when power is restored.
