4. Setup and Installation
The DAUZ WK-004 controller is designed for direct installation or integration into industrial control equipment panels. Ensure all power is disconnected before proceeding with installation.
- Mounting: Install the controller into a panel opening of approximately 157 x 76 mm. Secure it using the provided clips or mounting hardware.
- Wiring: Connect the power supply (110-230V) to the designated terminals. Connect the NTC temperature probe to the appropriate input terminals. Connect your heating and cooling devices to the 4 independent relay output terminals as required for your application. Refer to the wiring diagram on the back of the unit for precise connections.
- Probe Placement: Position the waterproof NTC probe in the environment where temperature measurement and control are needed. Ensure the probe is securely placed and not exposed to direct physical damage.
- Initial Power-Up: After all connections are secure, apply power to the unit. The digital display should illuminate.

5. Operating Instructions
The WK-004 controller allows for independent temperature and time settings for each of its four channels.
- Power On/Off: The unit powers on automatically when connected to a power source.
- Temperature Setting: Press the 'Temperature Setting' button to enter temperature adjustment mode. Use the 'Add' and 'Subtract' buttons to set the desired temperature for the active channel. Repeat for each channel as needed.
- Time Setting: Press the 'Time Setting' button to enter time adjustment mode. Use the 'Add' and 'Subtract' buttons to set the desired operational time or delay for the active channel.
- Heating/Cooling Mode: Each channel can be configured for independent heating or cooling operation. Refer to the on-screen indicators (e.g., A0 for heating, A1 for cooling) and the specific programming instructions provided with the device for detailed mode selection.
- Alarm Thresholds: Set high and low temperature alarm thresholds to trigger alerts if the temperature exceeds or falls below the set limits. Consult the device's programming menu for setting these values.
- Error Correction: If temperature readings appear inaccurate, use the software error correction feature (range -9 to +9 ℃) to calibrate the sensor.

6. Maintenance
Regular maintenance ensures the longevity and accurate operation of your DAUZ WK-004 Digital Temperature Controller.
- Cleaning: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
- Probe Inspection: Periodically inspect the NTC probe for any signs of damage or corrosion. Ensure it is clean and free from debris that could affect its accuracy.
- Connection Check: Regularly check all wiring connections to ensure they are secure and free from loose contacts.
- Environmental Conditions: Ensure the controller is operated within its specified environmental conditions to prevent damage. The ABS material is resistant to heat and low temperatures, but extreme conditions should be avoided.
7. Troubleshooting
If you encounter issues with your DAUZ WK-004 controller, refer to the following common troubleshooting steps:
- No Display/Power: Check the power supply connection and ensure the voltage is within the 110-230V range. Verify that the power outlet is functional.
- Incorrect Temperature Reading: Ensure the NTC probe is correctly connected and fully inserted. Check the probe for physical damage. Use the software error correction feature if a consistent offset is observed.
- Alarm Triggering Frequently: Review your high and low temperature alarm settings. Ensure they are appropriate for your application. Check if the controlled environment is experiencing unusual temperature fluctuations.
- Output Not Activating: Verify that the heating/cooling mode and set points are correctly configured for the specific channel. Check the wiring to the connected device.
- Voltage Fluctuation Protection: The device is designed with protection against voltage fluctuations. If issues persist after a power surge, contact support.
