4. الإعداد والتثبيت

إشعار هام للسلامة: 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 مخطط الأسلاك

Refer to the following diagram for correct wiring connections. This model operates on DC 12V power supply.

الشكل 3: Wiring diagram for the STC-1000 12V temperature controller. Connections are for power supply, NTC sensor, heating relay, and cooling relay.

• المحطتان 1 و 2: Power Supply (DC 12V).
• المحطتان 3 و 4: NTC Sensor connection.
• المحطتان 5 و 6: Heating Relay Output (Connect to heating device).
• المحطتان 7 و 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 التركيب

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. تعليمات التشغيل

The STC-1000 operates in Celsius only. It cannot be switched to Fahrenheit.

5.1 تشغيل/إيقاف التشغيل

• اضغط على مفتاح الطاقة button (marked with ⏻) to turn the controller on or off.

5.2 ضبط معايير درجة الحرارة

The controller has two main temperature settings: the Set Temperature (ST) و ال Difference Temperature (DT), also known as hysteresis.

1. ل view the Set Temperature (ST): اضغط لفترة وجيزة على Setting (S) button. The display will show the current set temperature.
2. To modify the Set Temperature (ST):
   • اضغط مع الاستمرار على Setting (S) button for approximately 3 seconds until the display flashes.
   • استخدم أعلى (▲) or لأسفل (▼) buttons to adjust the desired set temperature.
   • اضغط على مفتاح الطاقة button to save the setting and exit, or wait for 10 seconds for it to save automatically.

5.3 Advanced Parameter Settings (F1-F4)

To access and modify advanced parameters:

1. اضغط مع الاستمرار على Setting (S) button for approximately 3 seconds until the display flashes.
2. أثناء وميض الشاشة، اضغط على Setting (S) button again (do not hold) to cycle through parameters F1, F2, F3, F4.
3. استخدم أعلى (▲) or لأسفل (▼) buttons to adjust the value of the selected parameter.
4. اضغط على مفتاح الطاقة button to save the setting and exit, or wait for 10 seconds for it to save automatically.

5.4 Heating and Cooling Modes

The STC-1000 automatically switches between heating and cooling based on the set temperature (ST) and difference temperature (DT).

• وضع التبريد: If the current temperature is higher than (ST + DT), the cooling relay activates. It deactivates when the temperature drops to ST.
• وضع التدفئة: If the current temperature is lower than (ST - DT), the heating relay activates. It deactivates when the temperature rises to ST.

6. الصيانة

• تنظيف: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• العناية بالمستشعر: Ensure the NTC sensor probe is clean and free from debris. While waterproof, avoid unnecessary physical damage to the probe or cable.
• الاتصالات: Periodically check wiring connections for tightness and signs of corrosion.
• بيئة: Operate the controller within the specified ambient temperature and humidity ranges to ensure optimal performance and lifespan.
