Compact dimensions and quiet operation
Enjoy convenient heating control with the SONOFF TRV-ZBT Gen 2 thermostatic radiator valve, which combines modern design with practical styling. Compared to the previous TRVZB generation, it features a 38% smaller volume, making it easier to install on radiators in tight spaces, such as under low windowsills or close to furniture. The compact design is complemented by a quiet valve regulation mechanism that minimises distracting noises during operation. This makes the valve perfect for living rooms, bedrooms, and other spaces where you want a peaceful environment and an unobtrusive design.
Clear colour IPS display
Keep your home temperature under control with the modern colour IPS display, which clearly shows the set and current temperature, operating mode, and other key information. You can easily rotate the screen by 90° in four directions, ensuring the readings remain easy to read regardless of how the valve is oriented on your radiator. Adjust your target temperature easily using the rotary dial directly on the device. The SONOFF Zigbee Thermostatic Radiator Valve Gen 2 thermostatic radiator valve provides intuitive control without you needing to reach for your mobile phone every time.
Three independent heating schedules
Tailor your home heating to your daily routine and enjoy a comfortable temperature exactly when you need it. The SONOFF TRV-ZBT lets you create up to three separate weekly schedules, which you can easily switch between based on your current needs. Each schedule covers all seven days of the week and lets you set up to 12 time periods with a custom target temperature for each day. This makes it easy to set up different configurations for your working week, weekends, or holidays. The valve then automatically regulates the heating according to your chosen schedule, so you do not have to keep adjusting the temperature manually.
Intelligent control for a more comfortable environment
The SONOFF Zigbee Thermostatic Radiator Valve Gen 2 TRV-ZBT thermostatic radiator valve offers advanced heating control options that help maintain a stable room temperature. Thanks to compatible external temperature sensor support, you can base heating control on the actual temperature in the room rather than just the value measured near the radiator. The practical open window detection automatically scales back heating during sudden temperature drops or when a connected sensor detects an open window. Adaptive PID control also continuously adjusts the valve opening level based on current heating demands. It also features a Boost mode for temporary intense heating and can link with other smart home sensors.
Advanced protective functions
Enjoy convenient heating control with a suite of practical safety and protection features. The SONOFF TRV-ZBT thermostatic radiator valve comes equipped with a child lock to prevent accidental setting changes, and a frost protection mode that maintains a minimum temperature to reduce the risk of freezing damage to your heating system. Automatic valve maintenance regularly exercises the mechanism to help prevent sticking and limescale build-up. It also features low battery alerts and lets you set a default valve position if the batteries run out. The valve offers practical features for more reliable everyday operation.
