• Page 2: Safety instructions Read this user manual completely before installing or commissioning the device and pay particular attention to the hazard information. The installation of this device and work on the 230 V network must only be carried out by an electrician. The device is not a toy. Do not allow children to play with it. This device may be used by children from 8 years of age and by persons with reduced physical, sensory or mental capacities, or a lack of experience and knowledge provided these persons are supervised or have been instructed in the safe use of the device. When remotely or automatically controlling a device, it is not always possible to guarantee that commands are actually executed or that the correct device status is displayed. This may lead to material damage and/or personal injury. You must ensure to the greatest extent possible that no person is endangered at the time of remote operation or automated control. Please take special care when setting up or adjusting the remote control or when using the automated control. Check the desired functionality at regular intervals.
• Page 3: Do not paint over the device or apply wallpaper or paste over it. The device is not suitable for disconnection. For safety and approval reasons, the device may not be modified without authorization. Any use other than that described in the user manual is considered improper and leads to exclusion of guarantee and liability. We accept no liability for material damage or personal injury caused by improper use or failure to observe safety instructions. Do not use the device if it has visible damage or a malfunction. Only operate the device indoors and avoid exposure to moisture, vibrations, sunlight, extreme temperatures, and mechanical stress. Do not open the device as it does not contain user-maintainable parts. Only use the device with original components and recommended products from Bosch partners. Only operate the device with the control element attached.
• Page 4: Product overview LED display Information area displays error codes or other additional information. Humidity displays room humidity in normal operation. Status LED indicates secondary temperature display reserved for further temperature values. Rotary knob/system button allows for adjustments. Status indicators show power supply loss and connection status. Child lock feature activated by pressing the system button for more than 3 seconds. Open window detection pauses heating/cooling mode. Room control modes include automatic, manual, and rest mode. Value display shows actual and set temperature along with other text information during errors or configuration.
• Page 5: The status LED shows the status of the room thermostat using flashing codes. Orange flash indicates pairing mode is active or the device is communicating with the controller. Green flash indicates pairing mode is successful or the process is confirmed. Red flash (1x) indicates the first tuning attempt was not successful; try again or reset the device to factory settings. If the process fails, contact the service department if necessary. Red flash indicates a functional error; look for information in the Smart Home app. Contact the service team if necessary. Flashes occur every 15 seconds.
• Page 6: Notes regarding installation The standards and directives applicable in your country must be observed during planning, set-up, operation and maintenance. Operation of the device is only permitted at 230 V/50 Hz AC voltage. Work on the 230 V network may only be carried out by an electrician. To avoid an electric shock on the device, please switch off the mains power. Failure to observe the installation instructions may result in fire or other hazards. Mounting must be carried out following the applicable requirements. The product is only intended for fixed installation in in-wall switch boxes with a minimum depth of 35 mm. The supplied wire bridge may only be installed with 230 V AC consumers. Non-observance can lead to destruction of the device, fire or electrical accident. When connecting the device terminals, ensure that permitted wires and wire cross sections are used.
• Page 7: The consumers connected to the relay outputs must have sufficient insulation. Observe the technical data, in particular the maximum permissible switching power of the relay and the type of consumer to be connected. The device should only be loaded to the specified power limit. Overloading may result in destruction of the device, fire or an electrical accident. The power circuit must be secured with a circuit breaker in accordance with EN 60898-1. Installation guidelines in accordance with the applicable national standards must be observed. The circuit breaker must be easily accessible for the user and labelled as a disconnecter for the device. When using the device in wet rooms, a minimum distance of 60 cm from wet areas must be maintained. Before you start, be sure to shut off the power circuit breaker. Connect the room thermostat II 230 V according to the connection diagram that suits you.
• Page 8: Operation with 230 V devices 230 V AC External conductor (230 V AC) Neutral conductor Voltage-free input. For 230 V devices, connect the supply voltage to “L” via a wire bridge. Switching output for consumers Connections for external sensors or potential-free contacts. External temperature sensor (available as optional accessory), e.g. installed in the floor. 230 V actuator
• Page 9: Operation with 24 V devices Description External conductor (230 V AC) Neutral conductor Voltage-free input. For 24 V devices, input for the external 24 V voltage supply. Switching output for consumers. Connections for external sensors or potential-free contacts. External temperature sensor (available as optional accessory), e.g. installed in the floor. 24 V actuator.
• Page 10: Operation with boiler External conductor (230 V AC) Neutral conductor Voltage-free input. Voltage-free output. Attach the in-wall housing to the wall box using suitable screws. Pay attention to correct orientation. Place the control unit on the in-wall unit and press it in until it clicks into place. Now switch the power back on. Tuning mode starts and is active for 3 minutes. Tuning mode can be restarted at any time by pressing the system button.
• Page 11: The room thermostat can be operated independently, with no connection to the Smart Home system. The range of functions is limited to displaying and controlling the room temperature in manual operating mode. Basic settings can be made on the device via an installer mode for initial start-up without a Smart Home system. Press and hold the rotary knob for at least 3 seconds until the display shows “INS”. By turning the knob, you can make a selection and confirm it by pressing the knob. Potential applications include 230 V/24 V actuators. Normally closed actuators are used in heating mode. Normally open actuators are also used in heating mode. The thermostat can operate with 2nd generation Bosch Smart Home radiator thermostats. Cooling mode is available for both normally closed and normally open actuators.
• Page 12: After connecting the room thermostat to the Bosch Smart Home system, you can also make all device settings in the Smart Home app. Ensure that you have a Bosch Smart Home controller and the Bosch Smart Home app and have successfully configured both. Now start the Bosch Smart Home app and select “Add new device”. You can reset the device to its factory settings as follows: Remove the control unit from the in-wall housing. When reinserting it, hold the rotary knob until “RES” appears on the display. Release the rotary knob and press it again. The device then restarts. When resetting to factory settings, the settings and information are only lost from the device and not from the Bosch Smart Home controller. To re-configure the device, first delete it in the device management section of the Bosch Smart Home app and then add it again in the usual configuring process.
