Description
The Taco Comfort Solutions LFA1203S-1 is a probe-type Low Water Cut-Off (LWCO) control engineered to protect hot water and steam boilers from the damaging effects of low water conditions. Designed for dependable, automatic operation, this unit operates on 120V power and features a convenient auto-reset function that restores normal boiler operation once safe water levels are re-established — eliminating the need for manual intervention after each low-water event.
