Description
The Xylem-McDonnell & Miller RB-24SE Low Water Cut-Off is a small and reliable safety control designed for residential and light commercial HVAC boiler systems. It automatically protects the boiler by shutting down the burner if the water level falls below acceptable limits, avoiding possible damage and ensuring operator safety. With its 24V technology, this control easily interfaces with contemporary hydronic heating systems, allowing for easy installation and reliably avoiding dry-steam events. Its primary advantages include protection against dry-firing, boiler longevity and enhanced system performance. For application in hot water boilers, it supports maintaining water levels in HVAC systems.
