Hydrolevel 1100H3 Low Water Cut-Off
When you are dealing with tight clearances in residential gas-fired boiler retrofits or new installs, the Hydrolevel 1100H3 Low Water Cut-Off (Part Number 45-1103) provides a reliable, probe-style protection solution. This 24Vac low water cut-off is engineered specifically for hot water boilers, utilizing advanced microchip technology to monitor water levels without the mechanical failures associated with float-style switches. The 1100H3 model identifies a low-water state and immediately interrupts the burner circuit to prevent dry-firing and heat exchanger damage. Once the water level is safely restored, the automatic reset functionality resumes normal operation, reducing unnecessary service calls. For rapid troubleshooting on the job site, the unit features a burner circuit test button to simulate a low-water condition and verify operation without draining the system. The integrated LED indicator lights provide instant status updates: green for power and amber for low water. Note that this specific 1100H3 sub-model is provided without a wiring harness, making it an ideal replacement for existing Safgard 1100 series installations or for custom field wiring.
- Compact Footprint: Designed for space-constrained applications including wall-hung boilers and narrow cabinetry.
- Simplified Maintenance: The probe-style sensor eliminates the need for periodic cleaning of moving parts common in float controls.
- System Diagnostics: On-board power and low water lights allow for immediate visual confirmation of the control status.
- Standardized Ratings: Rated for a maximum pressure of 160 PSI and water temperatures up to 250?F to handle high-demand residential loops.
Common Questions
Does the Hydrolevel 1100H3 require a specific wiring harness?
The 1100H3 (Part 45-1103) is the version of the 1100 series that does not include a pre-packaged wiring harness. It is intended for technicians who are either reusing an existing Safgard harness or performing custom wiring to the boiler's 24V transformer and burner circuit.
When should the burner circuit test button be used?
The test button should be utilized during annual maintenance or startup to ensure the electronic signal correctly interrupts the burner circuit. This allows you to verify safety logic without manually lowering the boiler's water level.
Can this unit be used on steam boilers?
No, the Safgard 1100 series is specifically designed for hot water (hydronic) residential boilers. For steam applications, a different series of Hydrolevel Safgard controls rated for steam environments is required.
