The most frequently asked questions about the installation of the radiator thermostat
Radiator Thermostat - Installation
Can I view the temperature measured by a thermostat (radiator thermostat, room thermostat, floor heating)?
The temperature measured at the thermostat can be displayed via Administration -> Devices -> Thermostats -> Select the corresponding thermostat -> "Measured temperature" section. The display already includes the set temperature adjustment. For technical reasons, the temperature is measured directly at the respective thermostat using a sensor. Therefore, there may be deviations from the temperature e.g. in the middle of the room. The deviating measurement at the thermostat module can be corrected by adjustment. Please note that parts of the described products and their functions may only be available in Germany and Austria.
How do I attach the Smart Home radiator thermostat (adapter, valve)?
You can attach the Bosch Smart Home radiator thermostat to almost all radiators. All you have to do is remove your old thermostat and attach the Bosch Smart Home radiator thermostat. You may need an adapter for your existing valve. If the supplied adapters do not fit, there is the possibility to purchase additional adapters. You can find an overview of the available adapters and their assignment to the different valve types
My radiator thermostat cannot be installed. What am I doing wrong (reset, factory setting, connection)?
In this case please go through the following steps: 1. Perform the installation again. To do this, please check whether the device has already been detected ("Devices" menu item) and remove it if necessary. 2. Carry out a reset before reinstalling. To do this, press and hold the mode button of the thermostat when inserting the batteries again until the LED of the thermostat flashes orange. Release the button briefly and press it again until the LED lights up green. 3. Please check that the batteries are inserted correctly and that the LCD display is active. Also make sure that the component is at least 1m away from the controller when learning. 4. Briefly disconnect the smart home controller from the power and try again. Please also see our reset video in this article. If you have problems viewing the video, you can also find our installation and reset videos on our Bosch Smart Home Youtube Channel at the following
During the installation of my radiator thermostat I hear strange noises. What is that (calibration, adapter)?
When calibrating the radiator thermostat during installation, quiet buzzing noises may occur. However, if during operation there are recurring loud or creaking noises audible on the thermostat, the thermostat may be faulty or not properly fixed. Please check the correct fastening of the radiator thermostat again. A few heater models require an adapter, which is included with the Bosch Smart Home radiator thermostat accessories. Please also refer to the operating / installation instructions, enclosed or under the following
How do I remove my old thermostat from the radiator (radiator thermostat)?
There are several ways to remove a radiator thermostat. The most common ones are: 1. Screw cap. Simply unscrewing it is sufficient. 2. Clip cap: the thermostat must be clipped off at the side. 3. Allen key closure: the thermostat must be removed from the side using an allen key. If in doubt, always seek the help of a professional. If you still have questions or problems with the integration, accessibility or use of the device, please contact our
I receive the error message "Valve travel too long" despite correct installation. What am I doing wrong (radiator thermostat)?
We are always anxious to enable an easy assembly for you. In your case it seems that the tappet of your radiator does not cover the required distance. If you are using an adapter, make sure that it is correctly mounted and completely rests on the valve. In addition, it is possible that your valve pin is calcified. Use pliers to try to extend and retract the pin slightly. If this does not work, please contact our and send us pictures of your radiator valve so we can check the problem.
The Bosch Smart Home radiator thermostat does not fit my heater. What can I do (adapter)?
If the Bosch Smart Home Radiator Thermostat does not fit on your radiator, it may be necessary to use one of the enclosed adapters. The enclosed adapters were selected according to the number of valves on the market. If the enclosed adapters do not fit your needs, you will find an overview of all possible adapters available in the retail market. If you are unsure, take 3 photos of your radiator valve from different angles and send them to our .

Radiator Thermostat - Operations
How does the temperature setting of my home (Bosch Smart Home App, radiator thermostat, room thermostats) work?
You can conveniently set the temperature of your home individually for each room via the Bosch Smart Home App. To do this, go to the start screen in the app and select the room in which you want to set the temperature. Now you can adjust the room temperature to suit your needs. You can do this by setting the heating and setback temperature and by adjusting the timer. You can also set the heating temperature manually, either by setting the manual mode or by adjusting the temperature in the app or directly on the thermostat / room thermostat. In this case, the manually set temperature remains set only until the next switching point. The switching points are used to set up a time profile. You can define a setback value and a heating value via the Bosch Smart Home App and set up to 13 switching points for each day. The thermostat automatically sets the stored temperature for the switching points stored in the time profile. This allows you to decide individually when you want to heat in which room and when not. If the thermostat is in "automatic mode", the temperature is regulated via the Bosch Smart Home App and the presets stored in it. Please also note the operating / installation instructions under the following
I have more than 2 Smart Home radiator thermostats in one room. Can I control the radiator thermostats individually (room thermostat, room temperature)?
At the moment our Smart Home App does not offer the possibility to control radiator thermostats individually. But you can get the system to do so by dividing a real room into several virtual rooms (for example, the "living room" becomes "living room left" and "living room right"). Then you move the desired radiator thermostats into the respective virtual room. This allows the different areas / radiator thermostats to be controlled independently of each other (via app or room thermostat (one room thermostat is then required for each virtual room)).
The room or thermostats do not go into setback mode, even though a window has been opened. What can I do?
Wait a few seconds after opening the door/window contact. If the room or thermostats still does not go into lowered mode, this may have various causes: 1. Check whether the window contact indicates opening and closing by the built-in LED. In addition, the window contact of the affected window must be assigned to the same room as the thermostat. 2. The components of the window contact must not be more than 8 mm apart and must be placed at the same height (lower edge) so that they can find each other. 3. The batteries must be correctly inserted in the window contact and in the thermostat. 4. Please check whether two or three LEDs on your Smart Home Controller are lit continuously, depending on whether you have activated remote access.
What is behind the service "ventilation detection" and what can I set (door / window contact, radiator thermostat)?
In your app, you can conveniently select which door / window contacts should use the ventilation detection under "Services" -> "Ventilation detection". Here you can set the reaction time after which the thermostat will be turned down. This saves the batteries of the radiator thermostats in case of impulse ventilation or if, for example, a balcony door is only opened briefly (to let a cat out, for example).
Can I use the thermostat without Smart Home Controller (radiator thermostat)?
You can of course use your thermostat without a Smart Home Controller. In this case you operate the thermostat manually directly on the device.
The connection is bad, the radiator thermostat is no longer accessible. What can I do?
Please check whether the thermostat can still be controlled manually. If this is the case, it is possible that the distance between the Smart Home Controller and the component is too great, or that other electronic products have a disturbing influence on the connection. If there are other electronic products in the vicinity of the Smart Home Controller and / or the radiator thermostat, please check if you can change the position of the components and if this will result in a change in the accessibility of your thermostat. Also make sure that the component is at least 1 meter away from the Smart Home Controller.
My radiator thermostat shows "SFA" on the display. What does this mean?
The SFA mode is the internal control mode of the unit and may have been triggered accidentally by pressing the circle button and minus button on the thermostat simultaneously for some time. The SFA mode can be exited by pressing the circle button on the thermostat for some time or by waiting a while.
Why does the Smart Home app show Fahrenheit instead of degrees Celsius (room thermostat, radiator thermostat, room temperature)?
For iOS devices (Apple), the temperature unit setting is defined centrally in the operating system. The apps usually use these settings. To change it, please go to the following path to the operating system settings: Settings -> General -> Language & Region -> Temperature unit. On Android devices this setting is usually controlled by the system language. A specific setting is usually not possible.
What happens if the batteries of my radiator thermostat run out (where does the thermostatic valve stop)?
The radiator thermostat can only act on the valve via motor power. This is no longer possible without the power supply from the batteries. Therefore, when the battery voltage falls below 2.1 volts, the radiator thermostat moves to the emergency position, i.e. a position with a valve opening of 15%. This means that it is no longer possible to maintain a specific temperature, but the 15% opening is in any case sufficient to maintain an approximately normal room temperature until the batteries have been replaced.
What do the warm phase, cold phase and rapid heating (radiator thermostat) mean?
"Warm phase" describes the temperature you want to have at home when you are present. "Cold phase" describes the temperature setting that should be active while you are absent. The Bosch Smart Home App allows you to store individual temperature profiles for each room. The "warm phase" and "cold phase" functions are available for this purpose. To set these profiles, select the respective room in the main menu of the app. With a wipe to the left, you can now choose between automatic or manual operation. If you move the screen further to the left, you will reach the timer. Here you can set and save individual switching times for heating or lowering for each day. Quick heating is achieved by clicking on the "rocket" symbol in the view for manual control of the thermostat. The thermostats increase the heat output considerably for a short period of time in order to bring the room temperature to the desired level as quickly as possible. HI" appears in the thermostat display.
How can I perform a reset on my radiator thermostat (factory setting, factory reset)?
If a factory reset has to be carried out on the thermostat, the batteries have to be removed first. When reinserting the batteries, hold down the "Mode" button (the lower button with the circle). Briefly release the button once the LED flashes orange. Now hold down the button again until "rES" disappears from the display. The LED will briefly light up in green at the same time. The device will then restart, which may take several seconds. Please also see our reset video in this article. If you have problems viewing the video, you can also find our installation and reset videos on our Bosch Smart Home Youtube Channel at the following
General information about radiator thermostat
Radiator Thermostat - General Information
How high is radiation exposure for the Smart Home radiator thermostat (radiation value)?
The thermostatic control valves communicate in the proprietary frequency range (frequency around 868 MHz) with the Smart Home Controller, at a maximum transmission power of 10 mW for a few milliseconds every few minutes, but for a maximum of 36 seconds within an hour. Since these are battery-powered end devices, great importance is attached to energy-optimized operation. This naturally also results in the lowest possible communication volume between the thermostatic control valve and the Smart Home Controller. In addition to the radiation power, the radiation exposure also depends on the duration and distance to the transmitter and is therefore also significantly lower than with other radio radiation sources (WLAN, cordless phones (DECT), mobile phones, etc.). For more detailed information, you can obtain information from the German Federal Office for Radiation Protection or similar institutions in other countries.
What are the technical data of the radiator thermostat?
What does the "child safety lock" option (radiator thermostat, room thermostat) do?
In the app settings of your thermostats, you can switch a "child safety lock" on or off. Changes can then only be made in your Smart Home App or via voice control.
