Setup and Installation
Proper installation is crucial for the accurate and safe operation of your temperature controller. Follow these steps to set up the device:
- Power Connection: Connect the 12V DC power supply to the INPUT terminals (red and black wires). Ensure correct polarity.
- Load Connection: Connect the device you wish to control (e.g., heating mat, fan) to the OUTPUT terminals (yellow and black wires).
- Temperature Probe: Insert the temperature probe into the environment where temperature needs to be measured. Ensure the probe is securely placed and not directly exposed to heat sources or extreme conditions that could affect its reading.
- Mounting: The controller can be embedded into a panel. The embedded hole size is approximately 73mm (2.9 inches) with a hole diameter of 4mm.

- Setting Start Temperature (P0):
- Press the SET button once to enter the internal menu. The display will show P0.
- Press the SET button again.
- Use the Up and Down arrow buttons to adjust the desired starting temperature.
- Setting Stop Temperature (P1):
- Press the SET button once to enter the internal menu.
- Use the Up and Down arrow buttons to navigate to P1.
- Press the SET button again.
- Use the Up and Down arrow buttons to adjust the desired stopping temperature.
- Setting Temperature Calibration (P2):
- Enter the internal menu by pressing the SET button once.
- Use the Up and Down arrow buttons to navigate to P2.
- Press the SET button again.
- Use the Up and Down arrow buttons to set the required calibration temperature. This feature allows you to fine-tune the temperature reading if there is a known offset.
The controller supports both Celsius (°C) and Fahrenheit (°F) display. Refer to the device's specific display for the current unit.
Maintenance
To ensure the longevity and accurate performance of your Haofy XH 3002 temperature controller, follow these maintenance guidelines:
- Cleaning: Gently wipe the device with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the casing or electronic components.
- Probe Care: Keep the temperature probe clean and free from debris. Avoid bending or damaging the probe cable.
- Environmental Conditions: Operate the controller within the specified applicable environment range (-15-55℃ / 20%-85%RH) to prevent damage from extreme temperatures or humidity.
- Power Disconnection: Always disconnect power before performing any cleaning or maintenance.
Troubleshooting
If you encounter issues with your temperature controller, consider the following common troubleshooting steps:
- No Power/Display:
- Check if the 12V power supply is correctly connected and functioning.
- Ensure the input wires are securely connected to the controller.
- Incorrect Temperature Reading:
- Verify the temperature probe is properly inserted and making good contact with the environment being measured.
- Check the probe for any visible damage.
- Use the P2 calibration setting to adjust the temperature if you have a known accurate reference thermometer.
- Output Not Activating/Deactivating:
- Review your P0 (start temperature) and P1 (stop temperature) settings to ensure they are configured correctly for your desired heating or cooling mode.
- Ensure the load device connected to the OUTPUT is functional and correctly wired.
- Display Error Codes: If the display shows an error code, consult the manufacturer's support for specific interpretations.
