- Storage: When not in use for extended periods, store the controller in a cool, dry place away from direct sunlight.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or not turning on. | No power supply. | Ensure the controller is securely plugged into a live power outlet. Check the outlet with another device. |
| Incorrect humidity readings. | Sensor is dirty or damaged; sensor is improperly placed. | Clean the sensor. Ensure the sensor is placed in an open area, away from direct moisture or heat. Try restoring factory settings. |
| Connected appliance not turning on/off as expected. | Humidity settings are incorrect; appliance is not working; controller malfunction. | Verify your start and stop humidity settings. Test the appliance by plugging it directly into a wall outlet. Restore factory settings on the controller. |
| Buttons are unresponsive. | Temporary software glitch. | Unplug the controller from the power outlet, wait 10 seconds, and plug it back in. If the issue persists, try restoring factory settings. |
8. User Tips
- For optimal performance, ensure the humidity sensor is placed in a central location within the controlled environment, away from drafts or direct appliance output.
- When setting the humidity range, allow a differential (e.g., start at 60%RH, stop at 55%RH) to prevent the connected appliance from cycling too frequently.
