Description
The Taco Comfort Solutions LFM0243S-1 is a 24-volt manual reset (M/R) Low Water Cut-Off (LWCO) control designed to safeguard hydronic boilers from the hazards of low-water conditions. Featuring a 3/4″ probe connection, this unit continuously monitors boiler water levels and shuts down the burner circuit when water drops below a safe threshold — preventing costly heat exchanger damage, dry-fire failures, and potential safety incidents.
As a manual reset device, the LFM0243S-1 requires deliberate operator intervention to restore system operation after a low-water lockout, ensuring that the root cause is identified and corrected before the boiler is returned to service. This added layer of protection makes it an ideal choice for commercial and residential hydronic heating systems where safety compliance and operational reliability are paramount.
