Resetting to factory settings
You can reset the device to its factory settings as follows:
Remove a battery. Replace the battery while holding the “○” button. Hold the button pressed until the status LED rapidly flashes orange and “RES” appears on the display. Now release the button briefly and press and hold it again until the LED lights green and the notification on the display disappears. The device then restarts. Please note that it can take a few seconds until the thermostat is ready for operation again. 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.
