Hydrolevel 1150 Low Water Cut-Off

The Hydrolevel 1150 Low Water Cut-Off is a specialized 120VAC safety control engineered for residential hot water boilers. Designed to provide critical protection against dry-firing, this Safgard 1150 model utilizes a non-moving electronic probe to monitor water levels. In a low water condition, the 1150 immediately interrupts the burner circuit to prevent catastrophic equipment failure. As an automatic reset LWCO, it restores power to the burner once the water level returns to a safe operating range, ensuring system continuity for gas or oil-fired applications.

Built for efficiency in tight mechanical spaces, the Hydrolevel 45-1150 features a compact NEMA 1 enclosure and includes a plug-in wire harness for streamlined integration. Field diagnostics are simplified via the burner circuit test button, which allows technicians to verify control functionality without draining the system or removing the probe. Dual LED indicators provide instant status updates for "Power" and "Low Water" conditions. This unit is rated for pressures up to 160 psi and water temperatures reaching 250?F, making it a robust choice for heavy-duty residential hydronic demand.

• Critical Safety Protection: Prevents boiler damage by de-energizing the burner circuit during low water events.
• Simplified Maintenance: Integrated test button enables functional checks without decreasing water levels.
• Streamlined Installation: Compact design with labeled quick-connect terminals and a wire harness for faster field wiring.
• Clear Diagnostics: High-visibility LEDs confirm power presence and alert technicians to low water calls.
• Versatile Compatibility: Designed for use with both gas and oil-fired residential boilers.

Common Questions

Does the 1150 require manual intervention after a low water event?
No, this model features an automatic reset, which means the burner will resume operation as soon as the water level reaches the probe tip.

Can this be used on steam boilers?
The Safgard 1150 is specifically calibrated for hot water boiler applications. Steam systems typically require the CycleGard series to account for water level fluctuations.

What is the proper way to test this LWCO during a service call?
Standard maintenance involves pressing the integrated test button. This should illuminate the amber LED and immediately break the burner circuit, confirming the internal relay is functioning correctly.
