The unit supports up to 96 switching operations per day (48 on, 48 off) with independent programming for each day of the week, allowing different schedules for weekdays and weekends.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation in consumer units, distribution boards and control panels where automated switching is needed, the E854 fits standard DIN rail or panel mounting configurations via its 3-pin plug-in connection. The digital LCD display shows the current time, programmed switching events and operating mode. A temporary manual override button allows instant switching without altering the stored programme, and a holiday mode suspends all programmed operations until reactivated.\u003c\/p\u003e\n\u003cp\u003eThe unit includes automatic BST\/GMT changeover, eliminating the need for manual time adjustment twice a year, and a 20-day battery reserve that retains all programmed settings and timekeeping during mains power loss. The 104mm diameter round housing with a white front and black base matches standard control panel aesthetics. The three brass contact pins at the rear provide the electrical connection and mechanical retention when inserted into a compatible socket.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.369\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.413\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.37\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e104\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e83\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e134\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e104\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e83\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e134\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_E854_datasheet.pdf\" target=\"_blank\"\u003eProduct Specification Sheet\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/manual_E850.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat load can the 20A rating handle?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 20A rating at 230V supports loads up to approximately 4,600W. This is sufficient for most domestic immersion heaters, small commercial heating circuits, and lighting banks. Check that the connected load does not exceed 20A continuous draw.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes the battery need replacing?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe internal battery provides 20 days of memory backup during mains power loss. Battery life depends on usage, but typical replacement is needed every 3-5 years. Refer to the product manual for battery replacement instructions.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan different switching times be set for weekdays and weekends?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes. Each day of the week can be programmed independently, allowing separate schedules for Monday-Friday and Saturday-Sunday, or any other combination needed.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is holiday mode?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eHoliday mode suspends all programmed switching operations, effectively disabling the timer without erasing the stored programme. When deactivated, the unit resumes the programmed schedule. This is useful when premises are unoccupied for extended periods.\u003c\/p\u003e","brand":"Sangamo","offers":[{"title":"Default Title","offer_id":45294038450443,"sku":"E854","price":258.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/E854_c98aea46-c7c6-45b4-8780-44352aed5c6a.jpg?v=1714667536","url":"https:\/\/niori.co.uk\/products\/sangamo-e854-round-pattern-digital-7-day-time-switch-3-pin-20a","provider":"Niori","version":"1.0","type":"link"}
