The thermostat communicates with the receiver over 868MHz radio at up to 30m indoors, removing the need for cable runs between the room thermostat and the heating system. The unit offers both 7-day and 24-hour programming modes, with up to 6 time\/temperature events per day.\u003c\/p\u003e\n\u003cp\u003eDesigned for central heating control in domestic settings, the Choice Plus suits homes where running wiring from a central location to the boiler cupboard would be disruptive or expensive. The thermostat fits on any wall within 30m of the boiler, typically positioned in a main living area or hallway where it can sense representative room temperatures. The receiver fits near the boiler and switches the heating circuit on and off based on wireless commands from the thermostat.\u003c\/p\u003e\n\u003cp\u003eThe control unit uses TPI (Time Proportional and Integral) switching, which cycles the boiler on and off in short bursts rather than waiting for the room to drop below the set temperature before firing. This reduces temperature swings and fuel consumption. Optimum Start learns how long the system takes to reach target temperature and fires the boiler early on cold mornings so the room is warm by the programmed time, while Delayed Stop runs the system briefly after a heating period ends to extract residual heat from the radiators. The thermostat runs on AA batteries (supplied) and indicates low battery status before power runs out.\u003c\/p\u003e\n\u003cp\u003eThe blue backlit LCD shows current room temperature, target temperature, time and day. Three front buttons (minus, OK, plus) provide menu navigation and adjustment. The pre-programmed schedule is ready to use out of the box but can be adjusted to match occupancy patterns. Temporary override allows manual adjustment without losing the programmed schedule, and frost protection mode maintains a 5°C minimum temperature when the property is unoccupied in winter.\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\u003e0.53\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.57\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e17.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e246\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\u003e55\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e508\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_CHPRSTATDPRF_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_CHPRSTATDPRF.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 wireless range between the thermostat and receiver?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 868MHz radio link operates up to 80m in open field conditions and up to 30m indoors through typical domestic walls.
