OPERATIONAL PRINCIPLE

• Timer Operation: Recycling delay timer with 10 min. ON, 15 sec. OFF cycle.
• Pressure Sensing Switch Operation: When the differential pressure exceeds the set point, the normally closed (NC) pressure-switch contact opens, signaling the microprocessor that the switch state has changed. The microprocessor then energizes the relay and begins the timing sequence.
