The thermostat unit mounts on any wall and runs on batteries (supplied), with a large rotary dial setting the target temperature from 5°C to 30°C and a digital LCD display showing the current room temperature.\u003c\/p\u003e\n\u003cp\u003eDesigned for heating control in homes and small commercial spaces, the system uses TPI (Time Proportional and Integral) control to modulate boiler operation based on how far the room temperature is from the set point. This reduces the frequency of full-burn cycles and improves heating efficiency compared to simple on\/off thermostats. The receiver unit carries a 16A volt-free contact rating and connects to most UK boiler systems regardless of voltage.\u003c\/p\u003e\n\u003cp\u003eThe thermostat offers three operating modes: Comfort (normal setpoint), Economy (reduced setpoint for when the space is unoccupied), and manual ON\/OFF. A frost protection mode prevents the temperature falling below 5°C if the system is left unattended. The electronic sensor provides faster response to temperature changes than mechanical bi-metal thermostats, and the battery-powered design means no mains wiring is needed at the thermostat location.\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\u003e0.42\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e0.46\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Gross Weight (KG)\u003c\/td\u003e\n\u003ctd\u003e13.8\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Length (mm)\u003c\/td\u003e\n\u003ctd\u003e198\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\u003e52\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Length (mm)\u003c\/td\u003e\n\u003ctd\u003e290\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOuter Width (mm)\u003c\/td\u003e\n\u003ctd\u003e410\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_CHPRSTATDRFB_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_CHPRSTATDRF.pdf\" target=\"_blank\"\u003eProduct Manual\u003c\/a\u003e\u003c\/p\u003e\n\u003ch5\u003eFrequently Asked\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eWhat boilers is this compatible with?\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe receiver provides a 16A volt-free contact, making it compatible with most UK boiler systems regardless of operating voltage.
