7. समस्या निवारण
If you encounter issues with your Inkbird controllers, refer to the following common problems and solutions:
| समस्या | संभाव्य कारण | उपाय |
|---|---|---|
| Display shows 'HHH' or 'LLL' | Sensor error or out of range. | Check sensor connection. Ensure the environment's temperature/humidity is within the device's operating range. Replace sensor if damaged. |
| Device not turning on/off as expected | Incorrect settings (set point, differential), device malfunction, or power issue. | Verify set point and differential settings. Check power supply to the controller and connected devices. Test devices independently. |
| Alarm constantly sounding | Temperature/humidity outside alarm limits, or alarm settings are too narrow. | Adjust alarm limits to suit your environment. Check if the environment is stable. |
