9. Troubleshooting
If you encounter issues with your radiator, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Radiator does not turn on. | No power, power cord loose, overheat protection activated. | Check power outlet, ensure cord is securely plugged in. Unplug and allow to cool for 30 minutes if overheat protection is suspected. |
| No heat output. | Temperature setting too low, operating mode incorrect, child lock active. | Increase target temperature. Select an appropriate operating mode (e.g., Comfort). Deactivate child lock. |
| Wi-Fi connection fails. | Incorrect Wi-Fi password, router too far, 5 GHz network used, radiator not in pairing mode. | Verify Wi-Fi password. Move radiator closer to router. Ensure router is broadcasting 2.4 GHz. Put radiator into pairing mode. |
