2. התקנה וחיווט
Proper wiring is essential for the safe and correct operation of the STC-3028 controller. Refer to the wiring diagram below for connection details. This model operates on a 12V AC input.
איור 2.1: Wiring Diagram for STC-3028 Controller. This diagram illustrates the connections for power supply, humidity sensor, and relay outputs for temperature and humidity control.
איור 2.2: מְפוֹרָט view of the wiring label on the STC-3028, showing pin assignments for power, sensor, and relay outputs.
הוראות חיווט:
- Power Supply (Pins 1 & 2): Connect your 12V AC power source to these terminals. Ensure correct polarity if applicable, though the diagram indicates AC. For DC 12V, typically pin 1 is positive and pin 2 is negative.
- Humidity Sensor (Pins 3, 4, 5): Connect the integrated humidity sensor to these pins. The sensor cable typically has a specific connector that matches the port.
- Temperature Control Output (Pins 6 & 7): These are the relay contacts for temperature control (10A/240VAC). Connect your heating or cooling device to these terminals.
- Humidity Control Output (Pins 8 & 9): These are the relay contacts for humidity control (10A/240VAC). Connect your humidifier or dehumidifier device to these terminals.
הערות חשובות:
- Strictly distinguish the interface of the relay, sensor, and power connections to prevent damage.
- Maintain a proper distance between the sensor down-lead and power wires to avoid interference.
- ודא שכל החיבורים מאובטחים לפני הפעלת חשמל.
3. הוראות הפעלה
The STC-3028 controller allows you to set desired temperature and humidity ranges for automatic control.
Setting Startup Temperature/Humidity:
- הקש על "לְמַעלָה" button (for temperature) or the "לְמַעלָה" button (for humidity) once to display the current startup temperature or humidity setting.
- Long press the respective "לְמַעלָה" button for approximately 3 seconds until the displayed value flashes.
- השתמש ב- "לְמַעלָה" ו "לְמַטָה" buttons to adjust the desired startup temperature or humidity.
- The setting will automatically save after a few seconds of inactivity.
Setting Stop Temperature/Humidity:
- הקש על "לְמַטָה" button (for temperature) or the "לְמַטָה" button (for humidity) once to display the current stop temperature or humidity setting.
- Long press the respective "לְמַטָה" button for approximately 3 seconds until the displayed value flashes.
- השתמש ב- "לְמַעלָה" ו "לְמַטָה" buttons to adjust the desired stop temperature or humidity.
- The setting will automatically save after a few seconds of inactivity.
כיול טמפרטורה ולחות:
To calibrate the temperature or humidity readings:
- For temperature calibration: Press the "לְמַעלָה" (temperature) and "לְמַטָה" (temperature) buttons simultaneously. Adjust the offset using the Up/Down buttons.
- For humidity calibration: Press the "לְמַעלָה" (humidity) and "לְמַטָה" (humidity) buttons simultaneously. Adjust the offset using the Up/Down buttons.
It is recommended to use a professional and trusted external sensor for accurate calibration.
4. תחזוקה
To ensure the longevity and accurate performance of your STC-3028 controller, follow these maintenance guidelines:
- ניקוי: נגב את הצג באופן קבוע.asinנגבו בעזרת מטלית רכה ויבשה. הימנעו משימוש בחומרי ניקוי שוחקים או ממסים.
- טיפול בחיישנים: Keep the integrated sensor clean and free from dust, debris, or moisture buildup, as this can affect reading accuracy. Do not immerse the sensor in liquids.
- תנאים סביבתיים: Operate the controller within its specified temperature and humidity ranges. Avoid exposing it to extreme conditions, direct sunlight, or corrosive environments.
- חיבורים: בדקו מעת לעת את כל חיבורי החיווט כדי לוודא שהם יציבים היטב וחופשיים מקורוזיה.
איור 4.1: The STC-3028 controller features a cooling grid design for effective heat dissipation, contributing to its operational stability.
5. פתרון תקלות
If you encounter issues with your STC-3028 controller, refer to the following common problems and solutions:
| בְּעָיָה | סיבה אפשרית | פִּתָרוֹן |
|---|---|---|
| Display shows "LLL" or "HHH" | Sensor error, disconnected sensor, or reading outside range. | Check sensor connection. Ensure the sensor is within the operating temperature/humidity range. Replace sensor if faulty. |
| Relay fails to switch (stuck ON/OFF) | Faulty relay, incorrect wiring, or power overload. | Verify wiring connections. Ensure connected load does not exceed 10A/240VAC. If problem persists, the relay may be faulty and require replacement or professional repair. |
| קריאות טמפרטורה/לחות לא מדויקות | Sensor dirty, sensor damaged, or calibration needed. | Clean the sensor. Perform calibration as described in Section 3. If readings remain inaccurate, the sensor may be damaged. |
| הבקר לא נדלק | אין ספק כוח, עוצמת קול שגויהtage, or faulty unit. | Check power connections and ensure 12V AC is supplied. Verify power source is functional. |
