Resetting a Bosch one thermostat can be a straightforward process, but it’s essential to follow the correct steps to ensure a successful reset. Whether you’re dealing with a Bosch one-stage thermostat, an eTRV (Electronic Thermostatic Radiator Valve), or a Bosch wireless thermostat, this comprehensive guide will walk you through the necessary steps to get your thermostat back to its factory settings.

Resetting a Bosch One-Stage Thermostat

  1. Locate the Thermostat: Identify the location of your Bosch one-stage thermostat on the wall. Ensure that it is in a visible and accessible spot for easy access.
  2. Power Off the Thermostat: Locate the power switch on the thermostat and slide it to the “Off” position. Wait for approximately 30 seconds to allow the thermostat to fully power down.
  3. Power On the Thermostat: After the 30-second wait, slide the power switch back to the “On” position. The thermostat should now be reset and ready for use.
  4. Tip: If the thermostat does not respond or display any changes after powering it on, check the circuit breaker or fuse that supplies power to the thermostat. Ensure that the power is properly restored before proceeding.
  5. Verify the Reset: Once the thermostat is powered on, check the display to ensure that the settings have been reset to the factory defaults. You may need to adjust the time, temperature, and other preferences to your desired settings.
  6. Note: The specific steps for resetting a Bosch one-stage thermostat may vary slightly depending on the model. Refer to the user manual for your specific thermostat model for more detailed instructions.

  2. Power Off the eTRV: Locate the button on the eTRV and press and hold it for approximately 10 seconds. The display should show “rST” to indicate that the reset process has begun.
  3. Confirm the Reset: Release the button and press it again to confirm the reset. The display should now show “0”, indicating that the eTRV has been successfully reset.
  4. Set the Temperature: Use the up and down buttons on the eTRV to set the desired temperature. The eTRV will now operate based on the new settings.
  5. Tip: If the eTRV does not respond or the display remains blank after the reset, check the battery level and replace the batteries if necessary.

Resetting a Bosch Wireless Thermostat

  1. Check the Boiler: Observe the boiler and see if it reacts in any way, such as displaying lights or making noise. If the blue light on the boiler is flashing, do not press the reset button.
  2. Reset the Receiver: Locate the receiver unit, which is typically installed near the boiler. Press the “Set” button on the receiver 4 times, then press the “OK” button. Next, press the “Set” button another 4 times, followed by the “+” button. The receiver’s display should now show “—“, indicating that the reset process is complete.
  3. Note: The specific steps for resetting a Bosch wireless thermostat may vary depending on the model. Refer to the user manual for your specific thermostat model for more detailed instructions.
  4. Tip: If the wireless connection between the thermostat and the receiver is not re-established after the reset, you may need to re-pair the devices. Consult the user manual for the pairing process.

Remember, the steps outlined in this guide are general guidelines, and the specific process may vary depending on the model of your Bosch thermostat. Always refer to the user manual for your specific model to ensure you follow the correct steps for a successful reset.
