FW (Feed-Water Control, Open PCB)
The FW is a UL353 approved Feed-Water Control typically used with conductivity probes, floats or switches for interfacing with pumps, valves, contactors or audible/visual devices. Its primary function is to regulate the "pumping up" or "pumping down" of water/liquid from a tank, sump, or system. The FW can also be used as a lower cost liquid level annunciator/alarm for fill, over-fill. leak or open/short circuit detection applications.
