Description
The Hydrolevel 650-P is a 120VAC low water cut-off (LWCO) control designed to protect steam and hot water boilers from dangerous low-water conditions. Engineered for dependable, automatic operation, this control continuously monitors boiler water levels and shuts down the burner whenever water drops below the safe minimum threshold — helping prevent costly boiler damage and potential safety hazards.
Key Features
- 120VAC operating voltage for compatibility with standard residential and light commercial boiler systems
- Automatic reset function restores normal operation once safe water levels are re-established
- Built-in test button allows technicians to verify proper cut-off operation without draining the boiler
- Indicator light provides clear visual confirmation of control status at a glance
- Includes EL1214-P sensing probe with long nut for secure, leak-free installation into the boiler tapping
- Part Number: 45-653
EL1214-P Sensing Probe
The included EL1214-P sensing probe with long nut is specifically matched to the 650-P control. The probe’s conductance-based sensing technology delivers accurate, reliable water level detection, minimizing nuisance trips while ensuring the boiler is never operated in a low-water condition.
Applications
- Residential and light commercial steam boilers
- Hot water boilers requiring low water protection
- Replacement or upgrade of existing low water cut-off controls
