TAXNELE STC-3028 Temperature and Humidity Controller

1. Einleitung

The TAXNELE STC-3028 is a versatile digital temperature and humidity controller designed for precise environmental management. It features a dual display for simultaneous monitoring of temperature and humidity, and can be configured to control both heating/cooling and humidification/dehumidification equipment. This manual provides essential information for the safe and effective installation, operation, and maintenance of your STC-3028 controller.

2. Produktüberschreitungview

The STC-3028 controller integrates a high-accuracy sensor to measure both temperature and humidity. Its front panel features two digital displays, one for temperature (left) and one for humidity (right), along with control buttons for setting parameters. Output relays allow connection to external heating, cooling, humidifying, or dehumidifying devices.

4. Installation

4.1 Montage

The STC-3028 is designed for panel mounting. Ensure adequate space for ventilation and access to wiring terminals. Refer to the dimensions below for proper cutout size.

4.2 Schaltpläne

WARNUNG: Ensure power is disconnected before performing any wiring to prevent electric shock or damage to the device. All wiring should be performed by a qualified professional.

The STC-3028 offers two primary wiring configurations depending on whether the load uses an independent power supply or shares the controller's power supply.

Figure 4.2: Wiring diagram for connecting the STC-3028 where the controlled load (e.g., heater, cooler) has its own independent power supply. The controller's power input (L, N) is separate from the load's power, and the controller's output terminals act as a switch for the load's circuit.

Figure 4.3: Wiring diagram for connecting the STC-3028 where the controlled load shares the same power supply as the controller. The controller's power input (L, N) also supplies power to the load through the controller's output terminals, which switch the live (L) connection to the load.

Ensure all connections are secure and correctly matched to the terminals. Incorrect wiring can damage the device or pose a safety hazard.

5. Bedienung

5.1 Ein-/Ausschalten

Once wired correctly, apply power to the controller. The digital displays will illuminate, showing the current temperature and humidity readings.

5.2 Einstellen der Temperaturparameter

1. Set Startup Temperature: Drücken Sie die "Hoch" button (labeled ▲1 or ▲ for temperature) once to display the current startup temperature. Long press the "Hoch" button for approximately 3 seconds until the display flashes. Use the "Hoch" Und "Runter" buttons to adjust the desired startup temperature. The setting will automatically save after a few seconds of inactivity.
2. Stopptemperatur einstellen: Drücken Sie die "Runter" button (labeled 1 or ▼ for temperature) once to display the current stop temperature. Long press the "Runter" button for approximately 3 seconds until the display flashes. Use the "Hoch" Und "Runter" buttons to adjust the desired stop temperature. The setting will automatically save after a few seconds of inactivity.

5.3 Setting Humidity Parameters

1. Set Startup Humidity: Drücken Sie die "Hoch" button (labeled ▲2 or ▲ for humidity) once to display the current startup humidity. Long press the "Hoch" button for approximately 3 seconds until the display flashes. Use the "Hoch" Und "Runter" buttons to adjust the desired startup humidity. The setting will automatically save after a few seconds of inactivity.
2. Stopp-Luftfeuchtigkeit einstellen: Drücken Sie die "Runter" button (labeled 2 or ▼ for humidity) once to display the current stop humidity. Long press the "Runter" button for approximately 3 seconds until the display flashes. Use the "Hoch" Und "Runter" buttons to adjust the desired stop humidity. The setting will automatically save after a few seconds of inactivity.

5.4 Temperature and Humidity Correction (Calibration)

To correct or calibrate the temperature and humidity readings, press the "Hoch" Und "Runter" buttons simultaneously. Follow the on-screen prompts to adjust the offset if necessary. This feature allows for fine-tuning the sensor readings to match a known reference.

6. Wartung

• Reinigung: Regularly wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents, as they may damage the casing oder Anzeige.
• Sensorpflege: Keep the sensor clean and free from dust or debris. Avoid exposing the sensor to extreme physical shock or corrosive environments, which can affect its accuracy and lifespan.
• Verbindungen: Periodically check all wiring connections to ensure they remain secure. Loose connections can lead to intermittent operation or device malfunction.

7. Fehlerbehebung

If you encounter issues with your STC-3028 controller, consider the following common troubleshooting steps:

• Kein Display/Stromanschluss:
  • Check the power supply connection to the controller. Ensure it matches the specified 12VDC input.
  • Vergewissern Sie sich, dass die Stromquelle aktiv ist und die korrekte Spannung liefert.tage.
• Falsche Messwerte:
  • Ensure the sensor is properly connected to the controller.
  • Check if the sensor is clean and unobstructed.
  • Perform a temperature and humidity correction (calibration) as described in Section 5.4 if you have a reliable reference instrument.
• Load Not Activating:
  • Verify that the wiring to the load is correct and secure, referring to Section 4.2.
  • Check the set startup and stop parameters for temperature and humidity to ensure they are configured to activate the load under current conditions.
  • Confirm that the load itself (e.g., heater, humidifier) is functional.
