The thermostat controls heating systems via a 10A switch rating at 240V AC and uses an electronic sensor for temperature measurement across a 5°C to 30°C adjustment range.\u003c\/p\u003e\n\u003cp\u003eDesigned for installation in care homes, student accommodation, rental properties, commercial offices and public buildings where thermostats need to remain locked to a set temperature, the Choice Plus prevents manual override while still allowing maintenance access. The large dial behind the cover allows quick temperature changes when the cover is removed, and the electronic sensor responds faster than mechanical bimetal thermostats to room temperature changes.\u003c\/p\u003e\n\u003cp\u003eThe TPI (Time Proportional and Integral) control algorithm cycles the heating on and off in shorter bursts as the room nears the target temperature, reducing overshoot and improving efficiency compared to simple on\/off switching. The 0.5°C and 1°C temperature swing settings determine how close to the target temperature the room must reach before the heating switches off, with the tighter 0.5°C swing giving more consistent temperatures at the cost of slightly more frequent cycling.\u003c\/p\u003e\n\u003cp\u003eThe matt black finish on the 90mm x 92mm faceplate suits commercial and modern residential interiors without drawing attention. The thermostat mounts to a standard UK single-gang back box and requires neutral and live wiring to the heating system relay or zone valve.\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\u003e0.19\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e9\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e90\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Width (mm)\u003c\/td\u003e\n\u003ctd\u003e46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Height (mm)\u003c\/td\u003e\n\u003ctd\u003e92\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e250\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e285\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Height (mm)\u003c\/td\u003e\n\u003ctd\u003e310\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_CHPRSTATTB_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_CHPRSTATT.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat does tamper-proof mean for this thermostat?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe thermostat has a protective cover that clips over the adjustment dial and is secured by a security Torx screw.

A 0.5°C swing gives tighter temperature control with more frequent cycling. A 1°C swing allows slightly wider temperature variation with less frequent switching, which may suit some heating systems better.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan this control underfloor heating or zone valves?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYes, provided the total load is within the 10A at 240V AC switch rating.
