ጠቃሚ የደህንነት ማስታወሻ፡- Wiring should only be performed by individuals familiar with electrical connections. Ensure the power supply is disconnected before attempting any wiring. This device operates on DC 12V. Incorrect wiring can damage the unit or pose a safety hazard.
The STC-1000 features a terminal block for connections. Refer to the diagram below for proper wiring. Strictly distinguish the interface of the relay, sensor, and power. The sensor lead and power wire should be kept at a proper distance to avoid interference.

ምስል 4.1፡ ከላይ እና ከታች views of the STC-1000 controller. The top view shows the display and buttons, while the bottom view reveals the terminal block with a clear wiring diagram for power supply, NTC sensor, heating output, and cooling output connections.
- Power Supply (12V DC): Connect your 12V DC power source to the designated terminals (often pins 1 and 2).
- NTC ዳሳሽ፡- Connect the NTC waterproof sensor probe to the sensor terminals (often pins 3 and 4). The sensor is non-polar, so connection order does not matter.
- የማሞቂያ ውጤት; Connect your heating device (e.g., heating pad, lamp) to the heating relay output terminals (often pins 5 and 6).
- የማቀዝቀዝ ውጤት; Connect your cooling device (e.g., fan, chiller) to the cooling relay output terminals (often pins 7 and 8).

5.1. Viewing Current Temperature
Upon powering on, the LED display will show the current temperature measured by the NTC sensor.
5.2. የሙቀት መለኪያዎችን ማቀናበር
- የቅንብር ሁነታን አስገባ፡ Press and hold the 'S' button for 3 seconds. The display will show "F1".
- መለኪያዎችን ያስሱ፦ ወደላይ ተጠቀም (▲) እና ታች (▼) buttons to cycle through parameters (F1, F2, F3, F4).
- View/Modify Parameter Value: While a parameter (e.g., F1) is displayed, press the 'S' button briefly to view its current value. Use the Up (▲) እና ታች (▼) buttons to adjust the value.
- አስቀምጥ እና ውጣ፦ After setting all desired parameters, press and hold the 'S' button for 3 seconds to save the settings and exit. If no button is pressed for 10 seconds, settings will be saved automatically, and the device will return to normal operation.
5.3. Parameter Functions
- F1: Temperature Setting Value (SV)
- This is the desired temperature you want to maintain.
- Range: -50℃ to 99℃.
- F2: Hysteresis/Difference Value (D)
- This value determines the temperature difference between the set point and when the heating/cooling output activates.
- Example: If SV = 25℃ and D = 2℃:
- የማሞቂያ ሁነታ; Heater turns on at 23℃ (SV - D), turns off at 25℃ (SV).
- የማቀዝቀዝ ሁኔታ; Cooler turns on at 27℃ (SV + D), turns off at 25℃ (SV).
- Range: 0.3℃ to 10℃.
- F3: Temperature Calibration (C)
- Used to correct any deviation between the displayed temperature and the actual temperature.
- Adjust this value if the sensor reading is consistently inaccurate compared to a known reference thermometer.
- Range: -10℃ to 10℃.
- F4: Delay Start Time (PT)
- Sets a delay before the heating or cooling output activates after the temperature condition is met. This protects compressors in cooling systems.
- Range: 0 to 10 minutes. (0 = no delay)
5.4. Heating and Cooling Modes
The STC-1000 automatically determines whether to operate in heating or cooling mode based on the relationship between the Temperature Setting Value (F1) and the Hysteresis Value (F2).
- የማሞቂያ ሁነታ; If the Start Temperature (F1 - F2) is less than the Stop Temperature (F1), the device operates in heating mode. The heater will activate when the temperature drops below (F1 - F2) and deactivate when it reaches F1.
- የማቀዝቀዝ ሁኔታ; If the Start Temperature (F1 + F2) is greater than the Stop Temperature (F1), the device operates in cooling mode. The cooler will activate when the temperature rises above (F1 + F2) and deactivate when it reaches F1.
6. ጥገና
- ማጽዳት፡ Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
- የዳሳሽ እንክብካቤ The NTC sensor probe is waterproof. However, avoid bending the cable sharply or subjecting it to excessive force. Periodically check the sensor cable for any signs of damage.
- የአካባቢ ሁኔታዎች; Ensure the controller is operated within the specified ambient temperature and humidity ranges to prevent damage.
- የኃይል አቅርቦት; Always use a stable 12V DC power supply. Fluctuations can affect performance or damage the unit.
7. መላ መፈለግ
| ችግር | ሊሆን የሚችል ምክንያት | መፍትሄ |
|---|---|---|
| Display shows "LLL" or "HHH" | Sensor error (open circuit or short circuit) or temperature out of range. | Check sensor connection. Replace sensor if damaged. Ensure temperature is within -50℃ to 99℃. |
| Display shows "---" | Sensor not connected or damaged. | Verify sensor connection. Replace sensor if necessary. |
| Controller not turning ON/OFF heating/cooling | Incorrect parameter settings (F1, F2, F4), wiring error, or faulty relay. | Review F1, F2, and F4 settings. Check wiring connections. Test heating/cooling devices independently. |
| ትክክለኛ ያልሆነ የሙቀት ንባብ | Sensor calibration needed (F3), sensor placement, or faulty sensor. | Use F3 to calibrate the temperature. Ensure sensor is placed correctly and not affected by external heat sources. Replace sensor if faulty. |
| ማሳያ ባዶ ነው | No power or power button is off. | Check 12V DC power supply connection. Press the power button. |
