Operating at 120 volts, it includes an integrated probe that senses water presence in the vessel. When water drops below the probe tip, the control interrupts the burner circuit, preventing dry-fire conditions that can cause catastrophic heat exchanger failure. This device is installed by licensed plumbers, HVAC technicians, or boiler specialists as a primary safety control in residential and light commercial heating systems.\u003c\/p\u003e\n\u003cp\u003eThe 100110095 is suited for residential and light commercial boiler applications where a probe-style low water cut-off is required. Probe-type LWCOs are commonly installed on steam boilers and hot water boilers where continuous water level monitoring is necessary to maintain safe operating conditions. The 120-volt operating voltage makes it compatible with standard residential and commercial boiler control circuits without additional transformers or step-down wiring.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eProbe-based water sensing interrupts burner circuit when water level drops below safe threshold\u003c\/li\u003e\n  \u003cli\u003e120-volt operating voltage compatible with standard boiler control wiring\u003c\/li\u003e\n  \u003cli\u003eDesigned to prevent dry-fire damage to boiler heat exchangers\u003c\/li\u003e\n  \u003cli\u003eFunctions as a primary safety control in hydronic and steam heating systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement low water cut-off control for residential and light commercial boilers requiring a 120-volt probe-type LWCO safety device.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed plumber, HVAC technician, or boiler technician in accordance with local mechanical codes and the boiler manufacturer's guidelines. Shut off power to the boiler and allow the system to cool and depressurize before removing or installing any controls. Verify the probe is fully seated and the electrical connections are secure before restoring power. Consult local jurisdiction requirements, as LWCO devices on steam and hot water boilers may be subject to ASME or jurisdictional inspection.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Low Water Cut-Off (LWCO)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperating Voltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSensing Method\u003c\/strong\u003e: Probe\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100110095\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51150099382578,"sku":"100110095","price":769.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305987840.jpg?v=1778606043","url":"https:\/\/voomisupply.com\/products\/ao-smith-100110095-low-water-cut-off-120v-with-probe","provider":"Voomi Supply","version":"1.0","type":"link"}
