The Safgard 1100 Series low water cut-offs by Hydrolevel combine Hydrolevel's 35 years of electronic boiler control experience, advanced microchip technology and design input from heating professionals. The result is the smallest, easiest-to-install, low water cut-offs available for residential hot water boilers. Hydrolevel controls utilize a non-moving, heavy duty, electronic probe to sense liquid levels. The probe can be installed in an equalizing line or directly into a boiler or water tank in accordance with manufacturers' instructions and local and State codes. When water is in contact with the probe, it completes a circuit between the stainless steel probe tip and the tank or boiler surface in which the probe is installed. When water level drops below the probe, the circuit opens. Hydrolevel low water cut-offs for hydronic heating systems use the water signal to allow the burner to operate. If the water level drops below the probe, the circuit opens and the cut-off shuts down the burner.
With today's homes designed to maximize living space, boilers are being squeezed into ever-smaller areas. In a closet, under the stairs or any tight spot, the compact size of the 1100 Series is designed to fit any application setting. Hydrolevel provides step-by-step, diagramed instructions for fast, easy installation and wiring. The Model 1100 includes a plug-in wire harness with labeled quick-connects for 24 volt wiring with no guessing. The Model 1100 and Model 1150 are the only cut-offs designed for residential water boilers to offer a test button. This feature allows for testing the control without lowering the water level. And with the 1100 Series, the prescribed maintenance does not require annual probe removal as with other brands. The 1100 Series features Power and Low Water indicating lights for easy troubleshooting. The 1100 Series cut-offs feature heavy duty relay contacts and a tough, impact-resistant housing made from state-of-the-art polymers.Hydrolevel 1100H3 Safgard Low Water Cut-Off with Burner Circuit Test Button Features:
