In on/off control the feed pump is switched on/off via a level sensor or a differential pressure sensor. When the water level falls to the “Pump on” level, the pump starts pumping a large quantity of relatively cold water into the boiler. This will reduce the quantity of steam and cause the steam pressure to fall.
