This ensures that you only use the energy you need, helping to reduce the amount you spend on heating your home. The Radiator Thermostat II can be controlled easily and conveniently from a couch via Google Assistant or Alexa, or even remotely controlled via the app when residents are away from home. For example, red LEDs indicate that the temperature is being increased, while blue LEDs show that the temperature is being lowered. However, the opening of 15% is in any case sufficient to maintain an approximately normal room temperature until a battery replacement can be made.

However, if loud or creaking noises can be heard repeatedly from the thermostat during operation, it could be defective or not properly fastened. The latter sends a notification via the app in the event of a low battery so that you can prevent failures. To prevent limescale in the radiator valves building up over time, they are opened regularly even during the heating break. Whether fully automated or flexibly controlled, the intelligently networked devices relieve you of daily tasks – for instance, they control lighting, shutters and thermostats for an optimal feel-good atmosphere – and simultaneously minimise your energy consumption.The door/window contact registers open windows and doors and tells the radiator thermostat that the temperature should be reduced. Depending on the settings you’ve used, this may mean that your heating shuts off before a room hits the set temperature.

Not being able to see the current temperature is hugely disappointing, since it makes it far harder to work out what’s going on and if the room is at the right temperature or not.

Battery warning: If the two AA batteries which can easily be replaced are getting low, you will be given a warning via app several weeks in advance so that you can replace them in good time. When it comes to battery life, something that is essential to consider when investing in a smart thermostat, the Bosch Smart Home Radiator Thermostat II comes with two AA batteries for providing reliable energy.

Adjust the temperature of your radiators with ease using the Worcester Bosch Smart Radiator Thermostat. The new Room Thermostat II offers even more efficiency and greater ease of use when controlling room temperatures in the Bosch Smart Home. Can be combined with the Radiator Thermostat with limited range of functions as a remote control, but without transmission of temperature values.It’s worth mentioning that to make your heating thermostat smart, the Bosch Smart Home controller is needed if you want to integrate the device into your system – please keep in mind that Radiator Thermostat II isn’t compatible with Bosch EasyControl. In your app, you can select which Door/window contacts should use the ventilation detection under "Services" >> "Ventilation detection".
