4. Einrichtung und Installation
Wichtiger Sicherheitshinweis: Installation should be performed by qualified personnel. Ensure power is disconnected before wiring to prevent electric shock. Strictly distinguish between power supply, sensor, and relay interfaces. Maintain proper distance between sensor down-lead and power wires to avoid interference.
4.1 Schaltplan
Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.
Abbildung 3: Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.
- Terminals 1 & 2: Power Supply (DC 12V).
- Terminals 3 & 4: NTC Sensor connection.
- Terminals 5 & 6: Heating Relay Output (Connect to heating device).
- Terminals 7 & 8: Cooling Relay Output (Connect to cooling device).
Ensure all connections are secure and insulated. Verify the power supply voltage matches the controller's requirement (DC 12V for this model).
4.2 Montage
The STC-1000 is designed for panel mounting. Cut an opening of 71mm x 29mm in your panel. Insert the controller and secure it using the provided clips or mounting brackets.
5. Bedienungsanleitung
The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.
5.1 Ein-/Ausschalten
- Drücken Sie die Netzschalter button (marked with ⏻) um den Controller ein- oder auszuschalten.
5.2 Einstellen der Temperaturparameter
The controller has two main temperature settings: the Set Temperature (ST) und die Difference Temperature (DT), also known as hysteresis.
- Zu view the Set Temperature (ST): Drücken Sie kurz die Setting (S) button. The display will show the current set temperature.
- To modify the Set Temperature (ST):
- Halten Sie die Setting (S) button for approximately 3 seconds until the display flashes.
- Verwenden Sie die AUF (▲) or UNTEN (▼) buttons to adjust the desired set temperature.
- Drücken Sie die Netzschalter button to save the setting and exit, or wait for 10 seconds for it to save automatically.
5.3 Advanced Parameter Settings (F1-F4)
So greifen Sie auf erweiterte Parameter zu und ändern diese:
- Halten Sie die Setting (S) button for approximately 3 seconds until the display flashes.
- Während die Anzeige blinkt, drücken Sie die Taste Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
- Verwenden Sie die AUF (▲) or UNTEN (▼) Schaltflächen zum Anpassen des Wertes des ausgewählten Parameters.
- Drücken Sie die Netzschalter button to save the setting and exit, or wait for 10 seconds for it to save automatically.
| Parameter | Beschreibung | Reichweite | Standard |
|---|---|---|---|
| F1 | Difference Temperature (Hysteresis): The difference between the set temperature and the temperature at which the relay switches off. | 0.3°C bis 10°C | 2.0°C |
| F2 | Highest Set Point Limit: Limits the maximum adjustable set temperature. | Set Temp to 110°C | 110°C |
| F3 | Lowest Set Point Limit: Limits the minimum adjustable set temperature. | -50°C to Set Temp | -50°C |
| F4 | Temperaturkalibrierung: Adjusts the temperature reading to match a known accurate thermometer. | -10°C bis 10°C | 0.0°C |
5.4 Heiz- und Kühlmodi
The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).
- Kühlmodus: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
- Heizbetrieb: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.
6. Wartung
- Reinigung: Wischen Sie die Oberfläche des Controllers mit einem weichen, trockenen Tuch ab. Verwenden Sie keine Scheuermittel oder Lösungsmittel.
- Sensorpflege: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
- Verbindungen: Periodically check wiring connections for tightness and signs of corrosion.
- Umfeld: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
7. Fehlerbehebung
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Display shows "EE" | Sensorfehler oder offener Stromkreis. | Prüfen Sie den Sensoranschluss. Ersetzen Sie den Sensor, falls er beschädigt ist. |
| Display shows "HHH" | Temperature exceeds upper limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Display shows "LLL" | Temperature falls below lower limit of measurement range. | Ensure the environment temperature is within the sensor's range (-50°C to 99°C). |
| Controller lässt sich nicht einschalten | Keine Stromversorgung oder falsche Lautstärketage. | Check power connections and ensure DC 12V is supplied. |
| Heizung/Kühlung aktiviert sich nicht | Incorrect temperature settings (ST, DT), wiring error, or device malfunction. | Verify ST and DT settings. Check heating/cooling device wiring. Ensure the device is within operating parameters. |
