5. Product Overview
The W2062C controller features a dual digital display and two control buttons:
- Display: The upper (red) display shows the current humidity, and the lower (blue) display shows the set humidity.
- Buttons: 'SET' and 'ENT' (Enter) buttons are used for setting parameters.
6. Setup
6.1 Wiring Instructions
Connect the power supply and the load to the controller as shown in the wiring diagram. Ensure all connections are secure and correct, especially for high power loads connected to the 10A relay.
- Power Input: Connect your DC 12V or 24V power source to the designated input terminals.
- Load Connection: Connect your dehumidifier or humidifier (load) to the relay output terminals.
7. Operating Instructions
7.1 Setting Desired Humidity
- The upper red display shows the current humidity, and the lower blue display shows the set humidity.
- To set the desired humidity, press the 'SET' button and then use the '+' (STG) or '-' (ENT) buttons to adjust the value.
- After setting, wait for 3 seconds for the controller to automatically confirm and save the setting.
- The controller will then automatically energize the relay according to your set humidity parameters.
7.2 Advanced Parameter Settings (P0-P8)
To access the main menu for advanced settings:
- Press and hold the 'SET' button for 5 seconds.
- Use the '+' (STG) or '-' (ENT) buttons to navigate through parameters P0-P8.
- To adjust a specific parameter (e.g., P0), press the 'SET' button and '+' (STG) or '-' (ENT) simultaneously.
- Adjust the value as needed, then press 'OK' (likely 'ENT' button after adjustment) to confirm.
- Once confirmed, the controller will save the new parameter settings.
8. Maintenance
- Keep the controller and sensor clean and dry.
- Avoid exposing the sensor to direct water spray or extreme dust.
- Regularly check wiring connections for tightness and signs of wear.
- Do not attempt to disassemble or repair the device yourself, as this may void the warranty and pose safety risks.
9. Troubleshooting
| Symptom | Indicator/Display | Possible Cause / Solution |
|---|---|---|
| Relay not active | Indicator light OFF | Relay is currently off. Check set humidity vs. current humidity. |
| Relay active | Indicator light STEADY | Relay is closed (active). |
| Sensor error | Digital tube displays 'LL' | Sensor open circuit. Check sensor connection or replace sensor. |
| Measurement out of range | Digital tube displays 'HH' | Humidity is out of the measurement range. The relay will forcibly open. |
| Ultra-high humidity protection | Digital tube displays '-' | Device is in ultra-high humidity protection mode. |
10. User Tips
- When setting parameters, ensure you wait the full 3 seconds for the changes to be saved automatically.
- Always double-check your wiring, especially the polarity for DC inputs, to prevent damage.
