Description
The Weil McLain 540-130-968 LWCO Assembly with harness is a safety control assembly that monitors boiler water levels and interrupts operation if levels drop below safe limits in HVAC systems. It includes a low water cut-off (LWCO) part and wiring harness designed for EGH-85 to EGH-125 boilers, allowing proper integration with control circuits and safety controls . This is installed within boiler units, where it continuously checks water conditions during operation. Its role is to prevent dry firing by shutting down the system when low water conditions are detected, supporting safe and reliable heating performance.
