Description
The Taco Comfort Solutions LFA0243S-1 is a 24-volt, automatic-reset, no-test Low Water Cut-Off (LWCO) control designed to protect hydronic boilers from the hazards of low-water conditions. Featuring a 3/4″ probe connection, this LWCO continuously monitors boiler water levels and automatically shuts down the burner when water drops below a safe operating threshold — preventing costly damage and dangerous dry-fire situations.
With its automatic-reset (A/R) design, the control restores normal boiler operation once adequate water levels are re-established, eliminating the need for manual intervention. The no-test configuration simplifies installation and reduces maintenance overhead in applications where manual test functionality is not required.
Built to Taco Comfort Solutions’ exacting standards, the LFA0243S-1 is a dependable choice for residential and light commercial hydronic heating systems requiring reliable low-water protection.
