Warrick-Gems Sensors & Controls DFL1A0Z-04-04-15 Dual Function Level Control

The Warrick-Gems Sensors & Controls DFL1A0Z-04-04-15 Dual Function Level Control is an electronic monitoring component used in boiler and water management equipment in HVAC systems. It operates by sensing the presence of liquid through level probes or switches connected to it and by controlling two distinct level conditions. One circuit may control one level point, while the other controls the operation of the differential level. It is interpreted by internal circuitry and relays to operate to run pumps, alarms, or safety shutoff parts that are connected.
