Safeguard your hydronic or steam boiler system from critical failures with the McDonnell & Miller 144703 RB-122E. This essential safety control is designed to detect low water conditions instantly, preventing the boiler from firing when water levels drop below a safe threshold to avoid burner damage and overheating.

Utilizing a precise electronic sensing mechanism, the RB-122E monitors water levels within the boiler vessel. When the water level falls below the probe, the control interrupts the burner circuit, effectively locking out the boiler operation until water levels are safely restored, providing a reliable automated safeguard for your infrastructure.

Key System Performance Baselines:

  • Automatic Shutdown: Prevents dry-firing by cutting power to the burner during low-water events.
  • Solid-State Reliability: Electronic sensing technology ensures consistent performance with minimal mechanical wear.
  • Fast Response Time: Engineered for rapid detection to preserve internal heat exchanger integrity.

⚠️ Application Profile: Ideal for commercial and residential steam and hot water boilers requiring dependable low-water protection, secondary boiler safety circuits, and remote water monitoring integrations.
