5. Operating Instructions
5.1 ITC-308 Temperature Controller Operation
The ITC-308 allows you to set a desired temperature range. The heating device will activate when the temperature drops below the set point, and the cooling device will activate when it rises above the set point.
- View Set Temperature: Press the 'SET' button once to view the current set temperature.
- Set Temperature: Press and hold the 'SET' button for 3 seconds until the display flashes. Use the Up/Down arrows to adjust the desired temperature. Press 'SET' again to confirm.
- Temperature Calibration: Refer to the full user manual for advanced settings like temperature calibration and compressor delay.

6. Maintenance
Regular maintenance ensures the longevity and accuracy of your controllers.
- Cleaning: Wipe the controller units with a soft, dry cloth. Do not use abrasive cleaners or immerse the units in water.
- Probe Care: Keep the temperature and humidity probes clean and free from debris. Avoid bending or damaging the probe cables.
- Storage: When not in use, store the controllers in a cool, dry place away from direct sunlight and extreme temperatures.
7. Troubleshooting
If you encounter issues with your Inkbird controllers, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| 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. |
