5. Opstelling en installering
5.1 Veiligheidsmaatreëls
- Ensure the power supply is disconnected before any wiring or installation.
- Verifieer dat die voltage of your controller matches your power supply (12V, 24V, or 220V).
- All wiring should be performed by a qualified professional if you are unsure.
- Avoid installing the device in areas with excessive vibration, dust, or corrosive gases.
5.2 Bedradingsinstruksies
The controller has terminals for power input, temperature/humidity sensor, and output for controlled devices (e.g., heater, humidifier). Refer to the wiring diagram provided with your specific unit for precise connections. A general wiring principle is as follows:
- Connect the power supply to the designated input terminals (L and N for AC, + and - for DC).
- Connect the temperature and humidity sensor to the NTC terminals. Ensure the sensor is placed in the environment you wish to monitor and control.
- Connect your heating or cooling device (for temperature control) and humidifying or dehumidifying device (for humidity control) to the output relay terminals.

6. Bedryfsinstruksies
6.1 Aanskakel en vertoon
Once wired correctly, apply power to the controller. The digital displays will illuminate, showing the current temperature (℃) and humidity (%RH) measured by the sensor.
6.2 Setting Temperature and Humidity Parameters
To adjust the desired temperature and humidity set points:
- Druk en hou die STEL button for approximately 3 seconds to enter the parameter setting mode. The temperature display will start flashing.
- Gebruik die Up en Af arrow keys to adjust the desired temperature set point.
- Druk die STEL button again to confirm the temperature setting and move to the humidity setting. The humidity display will start flashing.
- Gebruik die Up en Af arrow keys to adjust the desired humidity set point.
- Druk die STEL button one more time to save all settings and exit the parameter setting mode. The displays will return to showing current readings.
The controller will now activate or deactivate the connected output devices based on your set parameters to maintain the desired temperature and humidity levels.
7. Onderhoud
7.1 Skoonmaak
- Wipe the controller's surface with a soft, dry cloth.
- Moenie skuurmiddels of oplosmiddels gebruik nie, aangesien dit die c kan beskadig.asing of vertoon.
7.2 Sensorversorging
- Keep the sensor clean and free from dust or debris to ensure accurate readings.
- Avoid submerging the sensor in liquids unless it is specifically designed for such environments.
- Do not bend or pull the sensor wire excessively.
8. Probleemoplossing
If you encounter issues with your ZFX-ST3022 controller, refer to the following table for common problems and solutions:
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
