Product information "Bosch Smart Radiator Thermostat II"

Smart heat at the touch of a button: With the Bosch Smart Radiator Thermostat II from, you can control your heating conveniently and efficiently.

Product highlight

  • Creates individual desired temperatures per room and displays the values in the app
  • Supports energy-efficient heating thanks to time programmes and smart services
  • Can be combined with other radiators to create one room temperature
  • Can be controlled flexibly - mobile or by voice
  • Temperature adjustable in 0.5 degree increments - via app or intuitively on the appliance by turning/pushing
  • Can only be used in combination with the Bosch Smart Home Controller

Flexible heating control - by voice, app & co

Whether with Alexa, Google Assistant or Siri in Apple HomeKit - you can also conveniently control your Bosch Smart Home radiator thermostats by voice command: "Alexa, set the temperature in the living room to 22 degrees." In addition to voice control, you have many other options for regulating your smart radiator thermostats:

  • Using pressure and rotary movements on the device
  • Via app - at home or remotely
  • Via automations - with the IF/THEN principle
  • Via time programmes - individually per room
  • With individual scenarios - for grouping several Smart Home thermostats/devices


Ventilate sustainably and save energy

The star of the fully automated control of the smart thermostats is the preconfigured "Sustainable ventilation" service, which links your door/window contacts with the heating control: If your door/window contact detects that a window is open, your smart radiator thermostats automatically reduce the heating in the room - optionally only after an individually adjustable delay if, for example, you regularly open your windows only briefly to let the cat out. The start and end of the heating pause during ventilation are reliably indicated by blue and red lights on the device. In this way, you never heat out the window again and save energy.


Recognise heating status by colour

It's not just networking with your smart home system that makes your heating thermostat smart - its design also sets it apart from conventional devices: Thanks to its compact size of 87 x 51 x 51 mm (LxWxD) and rotatable display, it blends discreetly into your living space - mounted either horizontally or vertically. The high-contrast display with backlighting guarantees optimum readability in all lighting conditions. Practical: The all-round visible illuminated ring of multi-coloured LEDs also indicates the actions performed and the status of the thermostat.


Use parental controls

Children's hands on heating thermostats can quickly lead to incorrect settings and wasted energy. Don't let them make you sweat (or freeze): Specify in the app or via the control button on the device that manual settings can no longer be made directly on the device. This way, the little ones can't adjust anything on the smart thermostats - and you can continue to control the room temperature conveniently via the app, voice assistant or room thermostat.


Being able to rely on protective functions

Literally "caught cold" by a heating failure? Not in a smart home! Your radiator thermostats help you to minimise the risk of a failure thanks to several protective functions:

  • Frost protection: Prevents damage to the radiator due to open windows or unused rooms.
  • Calcification protection: To prevent your thermostats from calcifying outside the heating period, the valve opens briefly once a week throughout the year.
  • Battery warning: If the two easily replaceable AA batteries run low, you will receive a warning via the app several weeks in advance so that you can replace them in good time.
  • Failure warning: Want to be on the safe side? Create an additional automation "IF room temperature below 15° THEN send message".


Easy to install

You don't need to be a heating professional to make your radiator thermostats smart. The Bosch Smart Home thermostats are quick and easy to install, even without an installer - the step-by-step instructions in the app guide you through the installation in a relaxed manner and thanks to the 2 AA batteries included, your thermostat is ready to go straight away. The smart thermostats are suitable for all radiators: either directly with M30 x 1.5 mm screw threads or using the included adapters (Danfoss RA, Danfoss RAVL).


Keep an eye on the temperature

With your smart thermostat, you can determine your individual comfort temperature per room to within half a degree and have an overview of the current temperature values in the app at all times.


Energy-efficient heating

The Smart Home radiator thermostat makes saving energy easy: thanks to time programmes and clever services such as "Sustainable ventilation", you only ever heat as much as is necessary for your comfort.


Network to room temperature

Several smart thermostats within a room can be combined in the app to create a room temperature and controlled in groups - optionally with a room thermostat for extra precision.
