Each channel supports 24-hour, 5\/2-day (weekday\/weekend) or 7-day programming with two or three ON\/OFF periods per day, allowing different schedules for weekdays, weekends and individual days of the week.\u003c\/p\u003e\n\u003cp\u003eDesigned for residential and light commercial installations, the programmer mounts on a standard UK single-gang back box and connects via 240V AC wiring with a 2A switch rating per channel. The boost function adds 1, 2 or 3 hours of heating or hot water outside the programmed schedule, while the holiday mode suspends all scheduled heating until a return date to prevent wasted energy during extended absences. A pre-programmed schedule is loaded at the factory, allowing the programmer to operate immediately after installation if the default timings suit the building.\u003c\/p\u003e\n\u003cp\u003eThe backlit display shows the current time, active channels (heating 1, heating 2, hot water) and programming mode on a blue LCD that remains visible in low light. The programmer includes automatic summer\/winter time change and an optional service interval function that can trigger a reminder when boiler maintenance is due. The matt black finish sits flush with the wall once mounted, and the six front-panel buttons (+HR and ADV for each of the three channels) allow manual override and schedule adjustment without removing the unit from the wall.\u003c\/p\u003e\n\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\u003e0.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.33\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e14.85\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\n\u003ch5\u003eDownloads\u003c\/h5\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/products_CHPPR3B_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_CHPPR3.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\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 one schedule for weekdays (Monday-Friday) and a different schedule for weekends (Saturday-Sunday). 7-day mode allows a unique schedule for each day of the week, giving maximum flexibility for irregular occupancy patterns.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the boost function work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePressing the +HR button on any channel adds 1, 2 or 3 hours of heating or hot water immediately, regardless of the programmed schedule. This is useful for unexpected hot water demand or when the house needs warming outside normal heating hours. The boost period expires automatically and the programmer returns to its scheduled operation.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat back box depth is required?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe programmer fits a standard UK single-gang back box. A 25mm minimum depth is recommended to accommodate wiring terminals and cable bends behind the unit.

Combi boilers typically require a simpler single-channel or 2-channel programmer since they heat water on demand rather than storing it. Check the boiler manufacturer's wiring diagram before installing.\u003c\/p\u003e","brand":"Sangamo","offers":[{"title":"Default Title","offer_id":45294157955339,"sku":"CHPPR3B","price":69.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0729\/8993\/3835\/files\/CHPPR3B_305efa61-8246-4606-b753-a4f0aaadaed9.jpg?v=1714668886","url":"https:\/\/niori.co.uk\/products\/sangamo-choice-plus-3-channel-digital-programmer-black","provider":"Niori","version":"1.0","type":"link"}
