2. સેટઅપ અને વાયરિંગ
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.
આકૃતિ 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.
આકૃતિ 2.2: વિગતવાર view of the wiring label on the STC-3028, showing pin assignments for power, sensor, and relay outputs.
વાયરિંગ સૂચનાઓ:
- 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.
મહત્વપૂર્ણ નોંધો:
- 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.

તાપમાન અને ભેજનું માપાંકન:
To calibrate the temperature or humidity readings:
- For temperature calibration: Press the "ઉપર" (temperature) and "Down" તથ્યો (temperature) buttons simultaneously. Adjust the offset using the Up/Down buttons.
- For humidity calibration: Press the "ઉપર" (humidity) and "Down" તથ્યો (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. જાળવણી
To ensure the longevity and accurate performance of your STC-3028 controller, follow these maintenance guidelines:
- સફાઈ: નિયમિતપણે ડિસ્પ્લે સાફ કરો અને સીasinનરમ, સૂકા કપડાથી ઘર્ષક ક્લીનર્સ અથવા સોલવન્ટનો ઉપયોગ કરવાનું ટાળો.
- સેન્સર કેર: 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.
- પર્યાવરણીય પરિસ્થિતિઓ: Operate the controller within its specified temperature and humidity ranges. Avoid exposing it to extreme conditions, direct sunlight, or corrosive environments.
- જોડાણો: સમયાંતરે બધા વાયરિંગ કનેક્શન્સ તપાસો જેથી ખાતરી થાય કે તે સુરક્ષિત અને કાટથી મુક્ત રહે.

5. મુશ્કેલીનિવારણ
If you encounter issues with your STC-3028 controller, refer to the following common problems and solutions:
| સમસ્યા | સંભવિત કારણ | ઉકેલ |
|---|---|---|
| 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. |
| તાપમાન/ભેજના અચોક્કસ રીડિંગ્સ | 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. |
| કંટ્રોલર ચાલુ થતો નથી | પાવર સપ્લાય નથી, ખોટો વોલ્યુમ છેtage, or faulty unit. | Check power connections and ensure 12V AC is supplied. Verify power source is functional. |
