Radiator Thermostat - Installation
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.
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 may need an adapter for your existing valve. If the supplied adapters do not fit, there is the possibility to purchase additional adapters.

During the installation of my radiator thermostat I hear strange noises. What is that (calibration, adapter)?

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.

My radiator thermostat cannot be installed. What am I doing wrong (reset, factory setting, connection)?
