- Set Starting Humidity:
- Press the Up button once to display the current starting humidity setting.
- Press and hold the Up button for 3 seconds. The starting humidity number will flash.
- Use the Up and Down buttons to adjust the desired starting humidity value.
- The setting will automatically save after a few seconds of inactivity, or you can press any other button to confirm.
- Set Stopping Humidity:
- Press the Down button once to display the current stopping humidity setting.
- Press and hold the Down button for 3 seconds. The stopping humidity number will flash.
- Use the Up and Down buttons to adjust the desired stopping humidity value.
- The setting will automatically save after a few seconds of inactivity, or you can press any other button to confirm.
- Restore Factory Settings:
- When the power is on, press and hold both the Up and Down buttons simultaneously.
- The digital display will show "888" and then automatically jump to detect the current humidity, indicating that the factory settings have been restored.
Note: The controller will activate the connected device (humidifier or dehumidifier) when the measured humidity falls below the set starting humidity or rises above the set stopping humidity, depending on the desired control mode (humidification or dehumidification). Ensure your connected appliance is set to its 'on' state for the controller to manage its operation.
7. Maintenance
To ensure the longevity and accurate operation of your Walfront WT-2000 Digital Humidity Controller, follow these maintenance guidelines:

- Sensor Care: Keep the humidity sensor clean and free from dust or debris. Avoid touching the sensor element directly.
- Storage: If storing the device for an extended period, unplug it and store it in a cool, dry place away from direct sunlight.
- Inspection: Periodically check the power cord and sensor cable for any signs of damage. If damage is found, discontinue use and contact support.
8. Troubleshooting
If you encounter issues with your WT-2000 Digital Humidity Controller, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | No power from outlet; loose connection; device malfunction. | Check the power outlet with another appliance. Ensure the controller is securely plugged in. If the issue persists, contact customer support. |
| Display shows "LLL" or "HHH". | Humidity sensor error; humidity out of measurable range (0-99% RH). | Check the sensor connection. Ensure the sensor is not damaged or exposed to extreme conditions outside its operating range. If the sensor is damaged, it may need replacement. |
| Connected appliance does not turn on/off as expected. | Incorrect humidity settings; appliance not in 'on' mode; appliance malfunction. | Verify the starting and stopping humidity settings (refer to Section 6). Ensure the connected humidifier/dehumidifier is powered on and set to operate when receiving power. Test the appliance directly in a wall outlet. |
| Inaccurate humidity readings. | Sensor dirty or obstructed; sensor placed in an unrepresentative location. | Clean the sensor gently. Relocate the sensor to an area that accurately reflects the humidity you wish to measure and control. |
| US plug does not fit the controller's socket. | Plug prongs have different sizes or an indentation that prevents full insertion. | Ensure the plug of your appliance has prongs of uniform size for proper fit. Some specialized US plugs may not be compatible. |
If these troubleshooting steps do not resolve the issue, please contact Walfront customer support for further assistance.
