Each day accommodates up to three ON\/OFF periods, allowing independent control of heating or hot water circuits in pumped central heating systems. The 2A switch rating at 240V AC handles standard zone valves, motorised valves and circulator pumps.\u003c\/p\u003e\n\u003cp\u003eDesigned for wall mounting in residential and light commercial heating systems, the programmer replaces mechanical timers with programmable control. The boost function adds 1, 2 or 3 hours of operation outside the set schedule, while the holiday mode overrides normal programming during periods away from the property. A pre-programmed schedule is loaded at the factory, so the unit can operate immediately on installation or be customised to match specific heating patterns.\u003c\/p\u003e\n\u003cp\u003eThe backlit blue LCD remains visible in low light and displays the current time, active programming day, and ON\/OFF status. Physical ADV and +HR buttons below the screen allow manual override without needing to navigate menus. The automatic summer\/winter time-change function adjusts the clock twice a year, while the service interval reminder can be enabled to prompt boiler maintenance at user-defined intervals. The black ABS housing measures 148mm wide, 90mm high and 42mm deep, fitting a standard back box or surface-mounting plate.\u003c\/p\u003e\n\u003ch5\u003eSpecification\u003c\/h5\u003e\n\u003ctable class=\"spec_table\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Net Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.31\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e14.4\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e148\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e235\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e460\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e305\u003c\/td\u003e\n\u003c\/tr\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_CHPPR1B_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_CHPPR1.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat's the difference between 24-hour, 5\/2-day and 7-day programming?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e24-hour mode repeats the same schedule every day. 5\/2-day mode allows different schedules for weekdays and weekends. 7-day mode provides independent programming for each day of the week, giving maximum flexibility for irregular routines.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow many ON\/OFF periods can be set per day?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eUp to three ON\/OFF periods per day, depending on the programming mode selected. This allows morning warm-up, daytime top-up, and evening heating cycles to be scheduled independently.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does the boost function do?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe boost function adds 1, 2 or 3 hours of immediate operation outside the programmed schedule. This is useful when extra heating or hot water is needed temporarily without changing the stored program.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIs this compatible with combi boilers?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe Choice Plus is a 1-channel programmer, meaning it controls a single heating or hot water circuit. Combi boilers typically require only heating control, as hot water is produced on demand. For systems with separate hot water tanks, a 2-channel programmer or dual-channel thermostat is needed to control heating and hot water independently.\u003c\/p\u003e","brand":"Sangamo","offers":[{"title":"Default Title","offer_id":45294150484235,"sku":"CHPPR1B","price":51.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/CHPPR1B_ded8b032-ce2d-4f4a-8247-9f7bf43cb26d.jpg?v=1714668705","url":"https:\/\/niori.co.uk\/products\/sangamo-choice-plus-1-channel-digital-programmer-black","provider":"Niori","version":"1.0","type":"link"}
