This essential safety device provides critical monitoring of boiler water levels, ensuring the unit shuts down immediately if water levels drop below safe operating thresholds, thereby extending the lifespan of your hydronic equipment.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eFPC-1000-P\u003c\/strong\u003e utilizes advanced probe-based sensing technology to detect the presence of water through conductivity. As the water level contacts the standard probe, it completes an electrical circuit, allowing the boiler to fire. Should the level recede, the circuit opens, signaling the control to de-energize the burner circuit to prevent thermal shock or heat exchanger failure.\u003c\/p\u003e\u003ch4\u003eKey System Performance Baselines:\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSafety Protocol:\u003c\/strong\u003e Immediate burner shutdown upon low water detection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProbe Sensitivity:\u003c\/strong\u003e Engineered for consistent response in standard hydronic boiler environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReliability:\u003c\/strong\u003e Robust solid-state switching circuitry for long-term operational integrity.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e⚠️ \u003cstrong\u003eApplication Profile:\u003c\/strong\u003e Ideal for commercial and residential steam or hot water boiler systems requiring reliable, maintenance-friendly water level management and dry-fire prevention.\u003c\/p\u003e","brand":"McDonnell \u0026 Miller","offers":[{"title":"Default Title","offer_id":43125826682974,"sku":"144705","price":312.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0663\/7151\/8558\/files\/144705_image_eca12eda-5542-4120-a417-d191a14c505e.png?v=1786039020","url":"https:\/\/nationalboilersupply.com\/products\/mcdonnell-miller-144705-fpc-1000-p-lwco-with-standard-probe","provider":"National Boiler Supply","version":"1.0","type":"link"}
