Burnham 100592-01 Hydrolevel Auto Reset High Limit Low Water Cut-Off 24V

The Burnham 100592-01 is a Hydrolevel automatic reset high limit low water cut-off control designed for safe operation of residential and light commercial boiler systems. This essential safety device monitors water levels and automatically shuts down the boiler when low water conditions are detected, preventing dangerous dry firing and potential damage to the heating system.

Key Features:

• 24-volt operation for standard residential boiler applications
• Automatic reset functionality returns system to normal operation once water levels are restored
• Built-in test button allows for quick manual testing of safety system
• High limit control provides additional overheat protection
• Reliable low water cut-off prevents boiler damage from insufficient water levels
• Designed for use with Burnham and compatible boiler systems

This control combines two critical safety functions in one device: low water cut-off protection and high limit temperature control. The convenient test button enables homeowners and technicians to verify proper operation without draining the system. When water levels drop below the safe operating threshold, the control immediately interrupts power to the burner, preventing costly damage and safety hazards.
