The unit controls a single output channel with up to three on\/off periods per day, operated through a backlit LCD interface showing time, day and program status. Two physical buttons (ADV and +HR) provide manual override and boost functions without accessing the main menu.\u003c\/p\u003e\n\u003cp\u003eDesigned for standard pumped heating systems, the programmer mounts on a standard UK back box and switches loads up to 2A at 240V AC, suitable for circulating pumps and zone valves in residential and light commercial installations. The unit comes pre-programmed with a default schedule that can be used immediately or overridden through the interface. A holiday mode allows temporary suspension of the schedule without losing stored programs, and an optional service interval reminder can be enabled for boiler maintenance tracking.\u003c\/p\u003e\n\u003cp\u003eThe 148mm x 90mm x 42mm housing fits a double-gang mounting footprint with a silver front panel and a backlit blue display visible in low-light conditions. The programmer includes automatic summer\/winter time adjustment for BST changes and retains program memory during brief power interruptions. At 0.31kg the unit installs without additional wall reinforcement on plasterboard or masonry surfaces.\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_CHPPR1S_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 uses one schedule for weekdays and a different schedule for weekends. 7-day mode allows a unique schedule for each day of the week, useful if occupancy patterns vary throughout the week.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHow does the boost function work?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe boost button (labelled +HR) activates heating immediately for 1, 2 or 3 hours regardless of the programmed schedule.
