The thermostat allows up to six time\/temperature events per day across a seven-day schedule, with each day independently programmable or grouped into 24-hour or 5\/2-day patterns. A pre-programmed schedule is loaded on first power-up, allowing immediate use without manual setup.\u003c\/p\u003e\n\u003cp\u003eDesigned for controlling heating systems in residential and light commercial applications, the Choice Plus uses TPI (Time Proportional and Integral) control to cycle the boiler on and off in short bursts rather than running continuously until target temperature is reached. This reduces overshoot, improves comfort and lowers gas consumption. Optimum start predicts when to fire the boiler to reach target temperature at the scheduled time, while delayed stop uses residual heat to avoid unnecessary boiler run time.\u003c\/p\u003e\n\u003cp\u003eThe black ABS housing measures 166mm wide by 90mm high with a 40mm projection from the wall once mounted. The LCD screen displays current room temperature, set temperature, time, day and mode status simultaneously. Three membrane buttons beneath the screen navigate the menu structure. The thermostat runs on two AA batteries (supplied) with a low-battery indicator on screen, and retains programming during battery replacement. Temperature control range is 5°C to 35°C with adjustable swing settings of 0.5°C or 1°C to fine-tune cycling behaviour. A frost protection mode maintains a minimum 5°C temperature when the schedule is overridden to 'off'.\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\u003e0.32\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.34\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e15.3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e166\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\u003e40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e225\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e510\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_CHPRSTATDPB_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_CHPRSTATDP.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is TPI control and why does it matter?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eTPI (Time Proportional and Integral) cycles the boiler in short on\/off bursts to maintain temperature rather than running flat-out until the target is reached.
