3. Configurazione e installazione

Installation of the Elitech STC-001 should be performed by qualified personnel to ensure safety and correct operation. Refer to the wiring diagram printed on the side of the unit for specific connection details. Ensure all power is disconnected before beginning installation.

3.1. Collegamenti elettrici

The controller typically requires connections for:

• Alimentazione elettrica: Connect to a stable 10A/220VAC power source as indicated on the wiring diagram.
• Sensore di temperatura: Connect the provided temperature sensor to the designated terminals. Ensure the sensor is placed in the area where temperature measurement is required.
• Refrigeration Output: Connect the refrigeration load (e.g., compressor) to the refrigeration output terminals.
• Defrosting Output: Connect the defrosting load (e.g., defrost heater) to the defrosting output terminals.
• Uscita di illuminazione: Connect the lighting load to the lighting output terminals.

Ensure all connections are secure and insulated to prevent short circuits or electrical hazards.

4. Istruzioni per l'uso

The Elitech STC-001 features a digital display and three control buttons: 'SET', 'Up', and 'Down'.

4.1. Accensione/spegnimento

The unit powers on automatically when connected to a power supply. There is no dedicated power button.

4.2. Viewing Current Temperature

Upon power-up, the display will show the current measured temperature from the sensor.

4.3. Impostazione dei parametri di temperatura

1. Press the 'SET' button once to enter the temperature setting mode. The display will flash, showing the current set temperature.
2. Use the 'Up' and 'Down' arrow buttons to adjust the desired temperature value.
3. Press the 'SET' button again to confirm the new setting and exit the setting mode. If no button is pressed for a few seconds, the unit will automatically save the setting and return to displaying the current temperature.

4.4. Impostazioni avanzate dei parametri

To access advanced parameters (e.g., differential, compressor delay, alarm limits, temperature calibration), typically a long press of the 'SET' button (e.g., 3-5 seconds) is required. Refer to the detailed parameter codes and their functions in the full product manual or on the manufacturer's website for specific adjustments.

4.5. Allarmi

The controller features high and low-temperature alarms, as well as a sensor fault alarm. When an alarm condition is met, the unit will typically display an error code or flash the temperature, and may activate an audible alarm if configured.

5. Manutenzione

Regular maintenance ensures the longevity and accuracy of your Elitech STC-001 controller.

• Pulizia: Periodically wipe the unit's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents.
• Controllo del sensore: Ensure the temperature sensor is clean and free from obstructions. Verify its placement for accurate readings.
• Connessioni: Occasionally check wiring connections for tightness and signs of wear or corrosion.
• Ventilazione: Ensure the unit's ventilation slots are not blocked to prevent overheating.

6. Risoluzione Dei Problemi

If you encounter issues with your Elitech STC-001, consider the following common troubleshooting steps:

• Display non funzionante: Controllare l'alimentazione e i collegamenti elettrici.
• Lettura errata della temperatura: Verify the sensor connection and placement. The sensor might be faulty and require replacement. Consider performing a temperature calibration if available in advanced settings.
• Temperature Not Controlling: Check the set temperature and differential settings. Ensure the load (refrigeration/defrosting) is correctly wired and functional.
• Allarme attivato: Identify the alarm code (if displayed) and consult the full manual for its meaning. Check if the temperature is outside the set alarm limits or if there's a sensor fault.
• Unità che non risponde: Disconnect power for a few minutes, then reconnect. If issues persist, consider restoring factory default settings (refer to advanced parameter settings).

Per problemi persistenti, contattare l'assistenza clienti o un tecnico qualificato.

7. Specifiche

While detailed specifications are typically found in the product packaging or official data sheets, the Elitech STC-001 generally operates with a 10A/220VAC power supply and is designed for precise temperature control in refrigeration and heating systems.
