When ambient or water temperatures drop to a critical threshold, the device signals the system to activate, preventing frozen pipes, heat exchangers, and related components. Licensed HVAC technicians, pool service professionals, and plumbers install this type of control as part of a broader freeze-protection strategy on outdoor or exposed equipment. The FG1-18P provides a reliable, automatic response to cold-weather conditions without requiring manual intervention from the operator.\u003c\/p\u003e\n\u003cp\u003eThe FG1-18P is suited for use on pool heaters, spa heaters, and hydronic heating systems where freeze protection is a code or manufacturer requirement. It is commonly installed on equipment located in regions subject to near-freezing or below-freezing ambient temperatures. Outdoor pool and spa heater installations are the most typical application, where water left sitting in heat exchangers or plumbing can freeze and cause catastrophic damage if no protective control is in place.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAutomatic freeze-protection response triggers system operation at low temperature thresholds\u003c\/li\u003e\n  \u003cli\u003eDesigned for outdoor pool, spa, and hydronic heating equipment\u003c\/li\u003e\n  \u003cli\u003eProtects heat exchangers and plumbing from freeze damage\u003c\/li\u003e\n  \u003cli\u003eDirect-replacement form factor for RAYPAK-equipped systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement frost guard control for RAYPAK pool and spa heating equipment.

Shut off all power to the heater unit at the disconnect before removing or installing any control component. Follow all applicable local mechanical and electrical codes, including NEC requirements for low-voltage control circuits. Do not bypass or jumper the frost guard circuit during testing without following the manufacturer service procedure.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 71562900812\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: RAYPAK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FG1-18P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"RAYPAK","offers":[{"title":"Default Title","offer_id":51383290396978,"sku":"FG1-18P","price":218.63,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/312678229.jpg?v=1782592344","url":"https:\/\/voomisupply.com\/products\/raypak-fg1-18p-frost-guard-temperature-switch","provider":"Voomi Supply","version":"1.0","type":"link"}
