FLLW (Tri-Function Control, Open PCB)
The FLLW is a Tri-Function Control that includes a primary and secondary Low-Water Cutoff and one Feed-Water control in a single compact space and cost saving design. The secondary Low-Water Cutoff is designed and approved as a UL353 limit control for Boiler applications and the other functions are approved for UL353 non-limit (ie; "Motor Control") requirements. This control can be used exclusively with conductivity probes for highest reliability or uniquely drop-in to support new or legacy designs with a mix of probe and float sensors.
