Hydrolevel CG450-1560 CycleGard Low Water Cut-Off 120V Steam Boiler Control with ILT

The Hydrolevel CG450-1560 CycleGard is a primary low water cut-off control designed specifically for residential and light commercial steam boilers, particularly oil-fired systems. This advanced safety device protects your boiler from dangerous low water conditions that could lead to equipment damage or failure.

Intermittent Level Test Technology:

The CG450-1560 features an innovative Intermittent Level Test (ILT) that automatically tests water levels every 15 minutes for 60 seconds. This critical safety feature removes power from the burner circuit at regular intervals, allowing foam to dissipate and water levels to stabilize for accurate readings—providing maximum protection against false signals caused by foaming and volatile water conditions in modern high-efficiency boilers.

Key Features:

• 120V AC operation with 15 PSI maximum pressure rating
• Electronic probe sensing with no moving parts for reliable operation
• 15-second burner off delay prevents short cycling from momentary water fluctuations
• 30-second burner on delay allows automatic water feeder to raise water level
• Automatic reset function after water reaches proper level
• Low water indicating LED light for visual status monitoring
• Direct boiler mounting eliminates need for external float chamber blowdowns
• Includes standard EL1214 3/4-inch NPT ceramic probe
• SPDT switching with 5.8 amp full load, 34.8 amp locked rotor capacity

The non-moving electronic probe senses water levels by completing a circuit between the stainless steel probe tip and the boiler surface. When water drops below the probe, the circuit opens and the control safely shuts down the burner. This probe-based design offers superior reliability compared to traditional float-type controls that can stick or fail mechanically.

Applications: Ideal for residential and light commercial steam heating boilers, particularly oil-fired systems, as well as certain low-pressure steam process applications. Can be installed in an equalizing line or directly into the boiler.

Note: This model replaces older part numbers 45-460-1560 and CG450-1090. Compatible with optional water feeders for automatic boiler water level maintenance.
