Hydrolevel 400R Safgard Steam Boiler Low Water Cut-Off 24V Remote Mount

The Hydrolevel 400R Safgard 400 Series is a 24-volt non-cycling steam primary low water cut-off designed for residential and light commercial steam heating boilers. This electronic control features a remote mounting configuration with the EL1214-R sensing probe and junction box for flexible installation options.

Key Features:

• 15-second burner off-delay prevents short cycling caused by momentary water level fluctuations
• 30-second burner on-delay allows automatic feeders to raise water level above the probe before restart
• Automatic reset after water reaches safe operating level
• Low water indicating light for visual status monitoring
• Electronic probe with no moving parts to wear or stick - eliminates need for blowdowns
• SPDT switch contacts with 50 VA switching capacity
• Maximum steam pressure rating of 15 PSI
• 3/4-inch NPT probe connection for easy installation
• 2 watt power consumption at 60 Hz

The control uses water as a conductor to complete the circuit between the stainless steel probe tip and the boiler shell. When water level drops below the probe, the circuit opens and the burner is de-energized after the 15-second safety delay. This reliable electronic operation provides high-quality, economical boiler protection with minimal maintenance requirements.
