Warrick DFL1A0Z040406 Control Els PW 29614 serving as the direct functionalThe Warrick DFL1A0Z040406 is a rugged, dual function control engineered for critical low water cutoff (LWCO) and differential level signaling. Designed as a solid state solution with no moving parts, this board effectively eliminates the mechanical failures common in float based systems. It features an integrated manual reset and a 3 second time delay on decreasing levels, specifically tuned to prevent nuisance tripping caused by turbulent liquid
