The Hydrolevel 500 is a 24-volt low water cut-off control designed specifically for hot water boiler systems. This essential safety device automatically shuts down the boiler when water levels drop below safe operating levels, preventing potentially dangerous dry-fire conditions and protecting your equipment from damage.

Key Features:

• 24VAC operation for compatibility with standard boiler control systems
• Manual reset function ensures operator awareness before system restart
• Built-in test button allows for regular safety checks without draining the system

The manual reset feature is a critical safety element that requires deliberate action to restart the boiler after a low water shutdown, ensuring that the underlying cause is addressed before resuming operation. The integrated test button enables routine verification of the control's functionality as part of regular maintenance procedures.
