IMPORTANT: A Hive Hub is required for app control, remote access, and heating schedules. These features are not available without a Hive Hub (not included). IMPORTANT COMPATIBILITY INFORMATION – Designed for Combi Boiler heating systems. This thermostat controls heating only and is not compatible with conventional boilers requiring separate heating and hot water control. New OpenTherm feature - OpenTherm tells heating controls and boilers precisely how much heat is needed to reach and maintain the target temperature. Improving efficiency from up to 12% lower gas consumption, extended lifespan of boilers, and more consistent room temperatures. Providing cost savings, added comfort, and a more sustainable home. Easy to Use – Change the temperature quickly and easily on the thermostat itself. A Hive Hub is required (not included) to use the Hive app, create heating schedules, boost your heating or hot water, and use Holiday Mode. Geolocation – With a Hive Hub (not included) and the Hive app, you'll receive a reminder to turn off your heating if you leave home when it is scheduled to come on. Requires a Hive Hub (not included) to create and edit heating schedules – set up to six daily heating time slots per day, seven days a week.
