4. Configuración y cableado

Nota importante de seguridad: 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.

1. Power Supply (12V DC): Connect your 12V DC power source to the designated terminals (often pins 1 and 2).
2. Sensor NTC: 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.
3. Salida de calefacción: Connect your heating device (e.g., heating pad, lamp) to the heating relay output terminals (often pins 5 and 6).
4. Salida de enfriamiento: Connect your cooling device (e.g., fan, chiller) to the cooling relay output terminals (often pins 7 and 8).

Asegúrese de que todas las conexiones estén seguras y aisladas para evitar cortocircuitos.

5. Instrucciones de funcionamiento

The STC-1000 features a digital display and four control buttons for easy operation.

• Botón de encendido (⏻): Presione para encender/apagar el dispositivo.
• Botón 'S' (Establecer): Used to enter and exit parameter setting mode.
• Arriba (▲) Botón: Aumenta valores o navega a través de las opciones del menú.
• Abajo (▼) Botón: Disminuye valores o navega por las opciones del menú.

5.1. ViewTemperatura actual

Upon powering on, the LED display will show the current temperature measured by the NTC sensor.

5.2. Ajuste de parámetros de temperatura

1. Ingrese al modo de configuración: Press and hold the 'S' button for 3 seconds. The display will show "F1".
2. Parámetros de navegación: Utilice el Up (▲) y abajo (▼) buttons to cycle through parameters (F1, F2, F3, F4).
3. 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 (▲) y abajo (▼) botones para ajustar el valor.
4. Guardar y Salir: 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℃:
    • Modo de calefacción: Heater turns on at 23℃ (SV - D), turns off at 25℃ (SV).
    • Modo de enfriamiento: 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. Modos de calefacción y refrigeración

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).

• Modo de calefacción: 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.
• Modo de enfriamiento: 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. Mantenimiento

• Limpieza: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Cuidado del sensor: 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.
• Condiciones ambientales: Ensure the controller is operated within the specified ambient temperature and humidity ranges to prevent damage.
• Fuente de alimentación: Always use a stable 12V DC power supply. Fluctuations can affect performance or damage the unit.
