7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device not powering on | Batteries incorrectly installed or depleted. | Check battery polarity; replace with new AA batteries. |
| Cannot pair with APP | TRV not in pairing mode; Zigbee gateway not connected; distance too far. | Ensure TRV is in pairing mode (flashing icon); check gateway connection; move TRV closer to gateway. |
| Inaccurate temperature reading | TRV is too close to a heat source or cold draft. | Ensure TRV is not obstructed or directly exposed to external temperature influences. |
| Radiator not heating/cooling | Valve stuck; TRV not properly mounted; system issue. | Check TRV mounting; manually check radiator valve operation; consult a heating technician if system issues are suspected. |
