2. Safety Information

To ensure safe operation and prevent damage, please observe the following safety precautions:

• Electrical Safety: Ensure all wiring is performed by a qualified professional and adheres to local electrical codes. Disconnect power before making any connections or performing maintenance.
• Voltage Compatibility: This device operates on AC 110-220V. Verify your power supply matches this requirement. Incorrect voltage can damage the unit.
• Load Capacity: The temperature control output is a 10A relay. Do not exceed this current rating to avoid overheating and potential damage to the device or connected equipment.
• Sensor Connection: Ensure the NTC temperature sensor is correctly connected and not damaged before use. A missing or faulty sensor will prevent proper operation.
• Environmental Conditions: Operate the device within the specified environmental requirements (-10 to 60°C, humidity 20%-85%RH) to ensure optimal performance and longevity.
• Waterproof Probe: The NTC probe is waterproof, but the main controller unit is not. Protect the main unit from moisture.

3. Package Contents

Upon opening the package, you should find the following items:

• 1 x Greluma W3230 Digital Temperature Controller
• 1 x NTC10K Waterproof Temperature Probe (1 meter length, stainless steel)

4. Product Overview

The Greluma W3230 features a clear digital display and intuitive controls for easy operation.

Components and Display

• Digital Display: Two digital tubes display temperature values. The upper display (PV) shows the actual measured temperature, while the lower display (SV) shows the preset temperature.
• Indicator Light (OUT): This light indicates the status of the relay. When the light is off, the relay is disconnected. When the light is on, the relay is closed (output is active).
• Buttons: The control panel includes three buttons: 'SET', 'Up' (▲), and 'Down' (▼). There is also a 'Restart' button.

6. Setup and Wiring

Proper wiring is crucial for the safe and correct operation of the temperature controller. Refer to the wiring diagram below.

Wiring Instructions

1. Power Supply: Connect the AC 110-220V power source to the +VCC and -GND terminals. Ensure correct polarity if applicable, though for AC, typically live and neutral.
2. Load Connection: Connect your heating or cooling device (load) to the S1 and S2 terminals. These terminals act as a switch controlled by the internal relay.
3. Sensor Connection: Plug the NTC temperature probe into the designated sensor port. Ensure it is securely connected.
4. Verification: Double-check all connections before applying power. Incorrect wiring can damage the device or connected equipment.

7. Operating Modes and Settings

The W3230 controller offers two main operating modes: Heating (H) and Cooling (C).

Basic Operation

1. Power On: After connecting the power, the upper digital tube (PV) will display the current measured temperature, and the lower digital tube (SV) will display the preset temperature.
2. Set Temperature: Press the 'SET' button once. The lower digital tube (SV) will flash. Use the 'Up' (▲) and 'Down' (▼) buttons to adjust the desired temperature. Press 'SET' again to confirm and exit, or wait 3 seconds for automatic saving.
3. Restart: The 'Restart' button can be used to reset the device.

Parameter Settings (P0-P8)

To access advanced settings, press and hold the 'SET' button for approximately 5 seconds until the display shows 'P0'. Use the 'Up' (▲) and 'Down' (▼) buttons to navigate through the parameters (P0-P8). Press 'SET' once to enter a parameter's setting, use 'Up'/'Down' to change the value, and press 'SET' again to confirm. Hold 'SET' for 3 seconds or wait for 10 seconds to exit the parameter setting mode.

8. Maintenance

To ensure the longevity and reliable performance of your Greluma W3230 Digital Temperature Controller, follow these maintenance guidelines:

• Cleaning: Wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off before cleaning.
• Probe Care: The stainless steel NTC probe is waterproof and resistant to rust. Periodically check the probe and its cable for any signs of damage or wear. Replace if necessary.
• Connections: Regularly inspect all wiring connections to ensure they are secure and free from corrosion.
• Environmental Protection: Keep the main controller unit away from direct water exposure, excessive dust, and extreme temperatures outside its operating range.

9. Troubleshooting

If you encounter issues with your temperature controller, refer to the following common problems and solutions:

Note: In protection mode (e.g., high/low temperature protection), the relay is automatically disconnected to prevent damage.
