4.2 Setting Temperature and Humidity
Use the SET button to enter the parameter setting mode. Navigate through settings using the arrow buttons and adjust values. Refer to the specific incubation requirements for your egg type for optimal settings.
- Temperature Range: 0°C - 99.9°C
- Humidity Range: 0% - 99% RH
4.3 Automatic Egg Turning Function
The thermostat supports automatic egg turning. This feature helps ensure even heating and development of the embryo.
- Egg Turning Cycle Setting: 0-999 minutes (interval between turns).
- Egg Turning Time Setting: 0-999 seconds (duration of each turn).
Adjust these settings via the SET button menu. Proper egg turning significantly improves hatching rates.

4.4 Alarm Functions
The thermostat is equipped with alarm functions to alert you to critical environmental changes:
- High/Low Temperature Alarm: Activates if temperature exceeds or falls below set thresholds. Can be configured to stop heating.
- High/Low Humidity Alarm: Activates if humidity exceeds or falls below set thresholds. Can be configured to stop humidification.
These alarm thresholds can be adjusted in the settings menu. Promptly address any alarms to maintain optimal incubation conditions.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your incubator thermostat.
- Cleaning: Gently wipe the exterior of the unit with a soft, dry cloth. Do not use abrasive cleaners or allow liquids to enter the device.
- Probe Care: Keep the temperature and humidity probes clean and free from debris. Avoid bending or damaging the probe wires.
- Storage: When not in use, store the thermostat in a cool, dry place, away from direct sunlight and extreme temperatures.
- Calibration: While the unit is factory calibrated, if you suspect inaccuracies, consult a professional for recalibration.
6. Troubleshooting
This section addresses common issues you might encounter with your incubator thermostat.
| Problem | Possible Cause | Solution |
|---|---|---|
| No Power | Power adapter not connected or faulty; power outlet issue. | Check power adapter connection. Ensure power outlet is functional. Test with another compatible DC12V power supply if available. |
| Incorrect Temperature/Humidity Reading | Probes are dirty, damaged, or improperly placed. | Clean probes. Ensure probes are securely connected and positioned correctly within the incubator, away from direct contact with water or heating elements. |
| Alarm Constantly Triggering | Temperature/humidity outside set range; alarm thresholds set too narrowly. | Verify incubator environment. Adjust alarm thresholds if necessary, ensuring they align with desired incubation parameters. Check for drafts or excessive moisture. |
| Egg Turning Not Working | Egg turning function disabled or incorrect settings. | Check egg turning cycle and time settings in the menu. Ensure the incubator's egg turning mechanism (if external) is properly connected and functional. |
If the problem persists after attempting these solutions, please contact customer support.
