5. Configurazione e cablaggio
Proper wiring is crucial for the safe and correct operation of the ZFX-ST3012 controller. Ensure power is disconnected before proceeding with any wiring.

Istruzioni di cablaggio:
Potenza in ingresso (AC220V): Connect the AC220V power supply to the terminals labeled '输入' (Input). Ensure correct live and neutral connections.
Uscita di carico: Connect your heating or cooling device (load) to the terminals labeled '输出' (Output). The controller acts as a switch for this load.
NTC Probes: Connect the two NTC temperature probes to the terminals labeled 'NTC'. The probes are non-polar, so connection order does not matter. Ensure probes are placed in the environment where temperature needs to be measured.
Montaggio: The controller can be mounted using the fixed M3 screw holes on its sides.
After all connections are securely made, you may apply power to the controller.
6. Istruzioni per l'uso
The ZFX-ST3012 controller is designed for straightforward operation. The left display shows the current temperature, and the right display shows the set temperature or parameter value.
Impostazione della temperatura target:
Premere il tasto IMPOSTATO button once. The right display will flash, indicating it's in setting mode.
Utilizzare il Freccia su or Freccia giù buttons to adjust the target temperature.
Premere il tasto IMPOSTATO button again to confirm the setting and exit. If no button is pressed for a few seconds, the setting will automatically save and exit.
Impostazioni avanzate dei parametri:
Per accedere alle impostazioni avanzate, tenere premuto il tasto IMPOSTATO button for approximately 3 seconds until the display shows 'P0'. Use the Freccia su or Freccia giù buttons to navigate through the parameters (P0-P8). Press IMPOSTATO una volta a view/edit a parameter, then use Su/Giù to change the value, and IMPOSTATO again to confirm. Hold IMPOSTATO to exit the menu, or it will exit automatically after a period of inactivity.

Note on P0 (Cooling/Heating Mode):
H (Heating Mode): The output will turn ON when the current temperature is below (Set Temperature - Hysteresis) and turn OFF when it reaches the Set Temperature.
C (Cooling Mode): The output will turn ON when the current temperature is above (Set Temperature + Hysteresis) and turn OFF when it reaches the Set Temperature.
7. Manutenzione
Regular maintenance ensures the longevity and optimal performance of your temperature controller.
Pulizia: Wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
Ispezione della sonda: Periodically check the temperature probes and their cables for any signs of damage, wear, or corrosion. Replace damaged probes immediately.
Verifica della connessione: Ensure all wiring connections remain secure. Loose connections can lead to intermittent operation or safety hazards.

Soluzione
Il display mostra 'HHH'
Temperature probe error (open circuit or temperature exceeds upper limit).
Check probe connection. Replace probe if damaged. Ensure temperature is within range.
Il display mostra 'LLL'
Temperature probe error (short circuit or temperature below lower limit).
Check probe connection. Replace probe if damaged. Ensure temperature is within range.
Display shows '---'
Nessuna lettura della temperatura.
Verify probe connection. Ensure probe is properly inserted.
Il controller non si accende
Nessuna alimentazione o cablaggio errato.
Check power connections (AC220V). Ensure power outlet is functional.
