It provides automatic reset functionality and includes an intermittent level test feature, which periodically verifies that the water sensing probe circuit is functioning correctly. The unit ships with the EL1214 probe. Licensed boiler technicians and heating contractors install this control as a safety device to shut down the burner when water level drops below a safe threshold, protecting the boiler from dry-fire damage.\u003c\/p\u003e\u003cp\u003eThis LWCO is intended for residential and light commercial steam heating systems where a 120-volt control circuit is present. It is well suited for hot water and steam boiler retrofit or replacement work where the existing low water cut-off has failed or requires upgrading to a unit with automatic reset and level-test capability. The intermittent test cycle reduces the need for manual float testing during routine maintenance visits.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAutomatic reset after water level is restored, reducing manual service calls\u003c\/li\u003e\n\u003cli\u003eIntermittent level test periodically exercises the probe circuit during operation\u003c\/li\u003e\n\u003cli\u003eIncludes EL1214 sensing probe in the package\u003c\/li\u003e\n\u003cli\u003eDesigned for 120-volt steam boiler control circuits\u003c\/li\u003e\n\u003cli\u003eReplaces legacy part numbers 450, OEM170TD, and MM PS-801-1080 for direct retrofit\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eThe cg450 directly replaces part numbers 450, OEM170TD, and MM PS-801-1080.

Shut off all electrical power to the boiler and allow the system to cool and depressurize before removing the existing LWCO or probe assembly. Verify that the replacement probe EL1214 is fully seated and that all wiring connections are secure before restoring power. Do not bypass or jumper the low water cut-off circuit during testing.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReset Type\u003c\/strong\u003e: Automatic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLevel Test\u003c\/strong\u003e: Intermittent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Probe\u003c\/strong\u003e: EL1214\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Steam Boiler\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HONEYWELL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: cg450\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HONEYWELL","offers":[{"title":"Default Title","offer_id":51233316733234,"sku":"CG450","price":352.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/21ikKQBQAwL.jpg?v=1780097179","url":"https:\/\/voomisupply.com\/products\/honeywell-cg450-low-water-cut-off-120v-steam-boiler","provider":"Voomi Supply","version":"1.0","type":"link"}
