Hydrolevel 24SV Low Water Cut-Off

The Hydrolevel 24SV Low Water Cut-Off is a heavy-duty electronic safety control designed for 24Vac hot water boiler applications. Engineered with a compact NEMA 1 enclosure, this unit is built for tight residential and light commercial boiler rooms where space is at a premium. The Hydrolevel 45-245 utilizes a specialized EL1214-SV sensing probe, which features a shorter length (2-1/16" insertion) specifically designed to fit into standard 3/4" NPT reducing tees without obstructing flow or causing clearance issues. As a probe-type LWCO, it utilizes the conductivity of water to complete a circuit, effectively preventing dry firing by immediately interrupting power to the burner if levels drop below the probe. Once the water level is restored, the automatic reset function re-energizes the system, ensuring continuous operation without manual intervention. This Safgard 24 series control operates at a sensitivity of 15,000 ohms and includes auxiliary contacts for an optional low-water alarm to provide enhanced system diagnostics and contractor notification.

• Optimized for Tight Spaces: The EL1214-SV short probe allows for installation in standard black iron tees, eliminating the need for specialized manifolds.
• Fail-Safe Protection: Protects against boiler damage caused by low water conditions with SPDT relay contacts rated for 5.8 FLA at 24V.
• Simplified Maintenance: Features an automatic reset and a diagnostic test button to confirm operation without draining the system.
• Versatile Compatibility: Designed for all types of hot water boilers with a maximum water temperature of 250?F and pressure up to 160 PSI.
• Reliable Sensing: Uses solid-state technology with no moving parts to hang up or wear out, outperforming traditional float-style controls.

Can the Hydrolevel 24SV be installed in a steam boiler?
No, this model is designed specifically for hot water boilers. Steam applications typically require the CycleGard series which includes an intermittent level test feature to account for surging and foaming.

What is the difference between the 24V and 24SV models?
The "SV" designation indicates the inclusion of the EL1214-SV short sensing probe. This shorter probe is necessary when mounting the control in a standard 3/4" pipe tee rather than a dedicated boiler tapping.

Does the 24SV require periodic maintenance?
While the electronic components are low-maintenance, the probe should be inspected annually for scale or sediment buildup, which can insulate the sensor and prevent accurate water detection.
