2.3 Initial Pairing (if required)
Upon first use, or after a long period of inactivity, the sensor may need to pair with your induction hob. Follow the pairing instructions provided in your Bosch induction hob's user manual. Typically, this involves activating the Perfect Cook function on the hob and ensuring the sensor is correctly placed in the cookware.
3. Operating Instructions
Once the sensor is correctly installed and paired, it will wirelessly communicate with your Bosch Perfect Cook induction hob to monitor and maintain precise cooking temperatures.
3.1 Temperature Monitoring
The sensor continuously measures the temperature inside your pot or pan. This data is transmitted to your hob, which then adjusts the heat output to maintain the desired temperature level for your cooking program.

3.2 Using Perfect Cook Programs
To utilize the sensor's full capabilities:
- Place the sensor into the compatible cookware.
- Place the cookware on a suitable cooking zone of your Bosch Perfect Cook induction hob.
- Select the desired Perfect Cook program on your hob's control panel. This may involve choosing a specific temperature level (e.g., for simmering, frying, or boiling) or a pre-set program for certain dishes.
- The hob will automatically adjust the power to maintain the target temperature, indicated by the sensor.
- Monitor the hob's display for status updates and completion signals.
The sensor helps prevent boil-overs and ensures consistent cooking, allowing you to focus on other tasks without constant supervision of your pot.
