{"product_id":"logix-740f-filter-controller","title":"Logix 740F Filter Controller","description":"\u003cp\u003eThe Logix 740F Filter Controller from Pentair is a replacement timer designed specifically for Autotrol Logix-series filter valves. As the electronic brain of the control head, it manages the timing and sequencing of the backwash and rinse cycles, keeping your filtration system cleaning its media bed on schedule so it can continue delivering consistent water quality without manual intervention.\u003c\/p\u003e\u003cp\u003eThis controller, also referenced as alternate part AT1242148, is the 740F filter version of the Logix platform. It is configured for filtration backwash duty rather than softener brining, which is an important distinction when selecting a replacement, since softener and filter controllers are not interchangeable despite their family resemblance. When an aging controller fails outright, loses its programming after a power event, or stops advancing cycles reliably, installing a fresh Logix 740F restores fully automated, dependable operation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eGenuine Pentair Autotrol Logix 740F controller\u003c\/li\u003e\n\u003cli\u003eType: replacement timer for filter valves\u003c\/li\u003e\n\u003cli\u003eControl type: Logix electronic control\u003c\/li\u003e\n\u003cli\u003eAlternate part number: AT1242148\u003c\/li\u003e\n\u003cli\u003eApplication: Autotrol Logix filter systems\u003c\/li\u003e\n\u003cli\u003eItem weight: 0.29 lbs\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eReplacing the controller is one of the highest-impact repairs you can make to an older backwashing filter, because a faulty timer compromises every cycle. A filter that does not backwash on schedule will gradually load up with trapped sediment, lose flow, and stop performing as intended, so restoring reliable control directly protects water quality and the life of the media bed.\u003c\/p\u003e\u003cp\u003eInstallers appreciate that the Logix platform is designed for a straightforward swap onto compatible valve bodies, which keeps service time and labor reasonable. Before ordering, confirm your valve is a Logix filter platform so the controller mates correctly and the programming options match your system's needs. After installation, take a moment to set or verify the backwash frequency and cycle times appropriate for your water and flow rate. With a healthy 740F controller in place, your filtration system returns to hands-off, scheduled backwashing and steady performance. Replacing an aging controller proactively also guards against being caught without backwash capability during a stretch of heavy use, when an unexpected failure would be most inconvenient. After installation, verify that the display powers up correctly and that the unit advances through a manual regeneration, which confirms the controller is communicating properly with the valve before you rely on it day to day.\u003c\/p\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":45668761403445,"sku":"AT740-FILTER","price":292.4,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0552\/4950\/2261\/files\/at740-filter_d7468912-d2d4-4aa1-9c64-0f0c96ab450e.jpg?v=1782532439","url":"https:\/\/watersoftenerplus.com\/hi-as\/products\/logix-740f-filter-controller","provider":"Water Softener Plus","version":"1.0","type":"link"}
