Hydrolevel 700 Low Water Cutoff Control 24V Manual Reset with 30-Second Lockout

The Hydrolevel 45-700 Safgard 700 is an electrically operated low water cutoff control designed for residential and commercial water boilers. This unit serves as the primary low water cut-off on water boilers or as a secondary control on commercial steam boilers. A probe is installed in the boiler shell or external manifold and connected to the control unit, using water as a conductor to complete the circuit between the probe and the boiler shell.

Key Features:

• Interrupts power immediately in a low water condition
• Burner circuit locks out if water remains below probe for 30 seconds
• Manual reset will not trip due to power failures
• Heavy-duty electro-mechanical design for long life
• Pressure rating up to 160 PSI for high-performance use
• Operates on 24VAC power
• Includes EL1214 sensing probe with 3/4-inch NPT connection
• No moving parts to wear, stick, or hang up as in float devices

Hydrolevel controls provide contacts to de-energize the burner circuit in a low water condition, automatically shutting off the burner to prevent boiler damage. The control utilizes a non-moving, heavy-duty electronic probe to sense liquid levels reliably. This low-maintenance design ensures consistent protection for your boiler system.
