1. Check Parameter: Under normal working status, press "up" key to display temperature setting value; press "down" key to display the difference value.

2. Set Parameter: Under normal working status, press "S" key for 3 seconds or more to enter parameter modifying mode. The "Set" indicator light will turn on, and the screen displays "F1". Use "up" or "down" keys to navigate menu items (F1-F4). Press "S" to view the parameter value. To adjust, press and hold "S" while pressing "up" or "down". After setting, press the power key to save and exit. If no key operation within 10 seconds, changes are not saved.

3. Restore System Data: If "Er" is displayed upon power-up, press any key to restore default values and enter normal working mode. It is advised to reset parameters after this.

STC-3000 Key Operation:

1. View พารามิเตอร์: Under normal working status, press "▲" once to display the temperature set value, press "▼" once to display the temperature difference set value. The display returns to normal after 2 seconds.

2. Set Parameter: Press and hold "S" for more than 3 seconds to enter parameter modification mode. The indicator light turns on, and the display shows "F1". Use "▲" or "▼" to navigate menu items (F1-F5). Press "S" to view the parameter value. To adjust, press and hold "S" while pressing "▲" or "▼". After setting, press the power button to save and exit. If no key operation within 10 seconds, changes are not saved. "Er" indicates a saving error.

3. Repair System Data: If "ER" is displayed on power-up, press any key to restore default parameters and resume normal operation. Reset parameters as needed.

℃/℉ Conversion: The STC-3000 supports both Celsius and Fahrenheit. Refer to parameter F5 in the menu. An image illustrating the conversion is provided below.

STC-3008 Key Operation:

1. Check Parameter: Under normal working status, press "up" key to display temperature setting value; press "down" key to display the difference value.

2. Set Parameter: Press "UP ①" and "UP ②" buttons simultaneously for 3 seconds to enter setting mode. The display shows "P0". Use "UP ②" and "DOWN ②" to adjust the parameter. Navigate through P0-P3 using "UP ①". After adjustment, wait a few seconds for automatic exit. For example, P0 is the first group temperature delay (0-60 min, default 0), P1 is the second group temperature delay (0-60 min, default 0), P2 is high temperature alarm (default 120℃), P3 is low temperature alarm (default -55℃).

3. Restore System Data: Press "Down ①" and "Down ②" buttons simultaneously for 3 seconds to restore factory settings.

• Long press "down" key for 3 seconds to make the stop temperature flash. Use "up" or "down" keys to set the stop temperature.

โหมดการให้ความร้อน: Start temperature < Stop temperature
โหมดทำความเย็น: Start temperature > Stop temperature

โหมดปกติ: Left red digital tube shows real-time temperature, right blue digital tube shows set temperature.
โหมดการตั้งค่า: Left red digital tube shows setting mode, right blue digital tube shows setting contents.

P0: Working Mode: Set to "H" for heating, "C" for cooling.

P1: Return Difference Value: The temperature difference at which the thermostat reactivates after reaching the set temperature. E.g., for 37-40℃ heating, difference is 3 degrees.

P2: High Temperature Alarm: When temperature reaches this value, an alarm sounds and operation stops.

P3: Low Temperature Alarm: When temperature falls below this value, an alarm sounds and operation stops.

P4: Temperature Correction: Corrects discrepancies between tested and real-time temperature. Final corrected temperature = tested temperature + correction. E.g., if tested 25.6℃, real 25.8℃, set P4 to 0.2.

P5: Delay Start: Used for compressor refrigeration. Set to 3-6 minutes based on compressor size.

P6: ℃/℉ Adjustable: Adjust unit for display. Long press "up" key for 3 seconds to quickly switch between °C and °F.

3. Restore System Data: Press "up" and "down" keys together for 2 seconds to restore the system.

STC-3028 Key Operation:

1. Check Parameter: Under normal working status, press "up 1" button to display temperature setting value; press "down 1" button to display the temperature difference value. Press "up 2" button to display humidity setting value; press "down 2" button to display the humidity difference value.

2. Restore System Data: Under normal working status, press "down 1" and "down 2" buttons simultaneously for 3 seconds. The LED digital display will show "888", then return to test temperature, indicating system restoration.

คำแนะนำการใช้งาน:

• Set Start Temperature (Humidity): Press the "up" button once to display the starting temperature (humidity). Long press the "up" button for about 3 seconds, then use "up" and "down" buttons to set the required value.
• Set Stop Temperature (Humidity): Press the "down" button once to display the stop temperature (humidity). Long press the button for about 3 seconds, and the stop temperature (humidity) number flashes. Use "up" and "down" buttons to set the required value.
• Temperature/Humidity Correction: Press "up" and "down" buttons at the same time. If the tested value differs from the real-time value, use this function to correct it. The final value = tested value + correction value. Press "up" and "down" buttons together for about 3 seconds to display "0.0", then adjust the correction value. Wait 5 seconds for the real-time display to update.

6 การแก้ไขปัญหา

This section outlines common issues and their solutions for the YIDI STC series controllers.

• "EE" Display: This indicates a sensor error (open circuit or short circuit). All running functions will stop, and the buzzer will alarm. Press any key to silence the alarm. The system will return to normal display once the sensor error is resolved.
• "HH" Display: This indicates that the measured temperature exceeds the temperature measuring range. All running functions will stop, and the buzzer will alarm. Press any key to silence the alarm. The system will return to normal operation once the temperature returns within the normal measuring range.
• "Er" Display (STC-1000, STC-3000): This indicates an error occurred while saving parameters. The system will return to the normal display state after 3 seconds. It is recommended to reset parameters after this occurs.
• การอ่านค่าที่ไม่ถูกต้อง: If the displayed temperature or humidity is inconsistent with actual conditions, perform a calibration using the temperature/humidity correction function (P4 for STC-3018, specific steps for STC-3028).
• คอนโทรลเลอร์ไม่ตอบสนอง: ตรวจสอบให้แน่ใจว่าแหล่งจ่ายไฟตรงกับปริมาตรที่ระบุtage (DC12V/DC24V/AC110V-220V). Check all wiring connections for looseness or incorrect placement.

7. การบำรุงรักษา

To ensure the longevity and optimal performance of your YIDI STC series controller, follow these maintenance guidelines:

• การทำความสะอาด: รักษาอุปกรณ์ให้สะอาด ปราศจากฝุ่นและสิ่งสกปรก ใช้ผ้าแห้งนุ่มๆ ในการทำความสะอาด ห้ามใช้สารทำความสะอาดที่มีฤทธิ์กัดกร่อนหรือตัวทำละลาย
• สภาพแวดล้อม : Avoid exposing the controller to environments with excessive dampness, high temperatures, strong electromagnetic interference, or corrosive substances.
• การดูแลเซ็นเซอร์: For models with NTC probe sensors (STC-1000, STC-3000, STC-3008, STC-3018), ensure the sensor is not submerged in water for extended periods unless specifically designed for such use. Regularly inspect the sensor and its cable for any signs of damage.
• การตรวจสอบสายไฟ: ตรวจสอบการเชื่อมต่อสายไฟทั้งหมดเป็นระยะๆ เพื่อให้แน่ใจว่ามีความปลอดภัยและไม่มีการกัดกร่อน
• แหล่งจ่ายไฟ: Ensure the power supply remains stable and within the specified voltage range for your model.

8. เคล็ดลับผู้ใช้

• ตั้งค่าเริ่มต้น: Before connecting any loads (heaters, coolers, humidifiers, dehumidifiers), it is recommended to power on the controller and familiarize yourself with the menu settings and parameter adjustments.
• การสอบเทียบ: For applications requiring high precision, always perform a temperature and/or humidity calibration using a known accurate reference instrument.
• การตั้งค่าล่าช้า: Utilize the compressor delay time (F3 for STC-1000/3000, P0/P1 for STC-3008, P5 for STC-3018) to protect refrigeration equipment from rapid cycling, which can extend its lifespan.
• Wiring Best Practices: When installing, route sensor cables and power cables separately to minimize electrical interference and ensure stable readings.
• ข้อมูลจำเพาะของแอปพลิเคชัน: For critical applications like hatcheries or cold storage, consider setting high and low alarm limits (P2/P3 for STC-3008/3018) to be alerted to deviations.
