It supports either electronic rectification or ultraviolet flame detection when used with the appropriate color-coded plug-in amplifier. The control performs a safe-start check to prevent startup in unsafe flame conditions and will lock out the system if a flame is not established during pilot trial. It also automatically recycles through a prepurge sequence if the flame signal is lost while in run. This model allows for variable prepurge durations through plug-in purge timers and offers built-in protection against ignition crossover in flame rod systems. With a rugged thermoplastic base and captive mounting screws, it is easy to install and service. The R4795A1008 weighs approximately 2.00 lbs and is rated for ambient temperatures from -20°F to +125°F (-29°C to +52°C).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFlexible Flame Detection: Supports UV or rectification detection with plug-in amplifiers.\u003c\/li\u003e\n\u003cli\u003eVariable Prepurge: Adjustable timing with plug-in purge timer cards.\u003c\/li\u003e\n\u003cli\u003eAutomatic Recycle: Returns to prepurge if flame is lost during operation.\u003c\/li\u003e\n\u003cli\u003eSafe-Start Logic: Prevents startup when unsafe flame conditions are detected.\u003c\/li\u003e\n\u003cli\u003eSolid-State Reliability: Durable electronics ensure stable performance over time.\u003c\/li\u003e\n\u003cli\u003eNo Alarm Contacts: Streamlined model for systems not requiring external alert circuits.\u003c\/li\u003e\n\u003cli\u003eEasy Installation: Captive screws and thermoplastic subbase simplify mounting and replacement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe \u003cspan data-sheets-root=\"1\"\u003eR4795A 1008\u003c\/span\u003e offers dependable flame supervision and burner control with flexible configuration and safety protections.\u003c\/p\u003e","brand":"Honeywell","offers":[{"title":"Default Title","offer_id":49105368547584,"sku":"R4795A 1008","price":3123.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/DeWatermark.ai_1753474695566.jpg?v=1785545665","url":"https:\/\/alotechparts.com\/products\/r4795a-1008-honeywell-boiler-fsg-programming-relay","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
