- Terminali 5-6: Power input (110V AC).
- Terminali 7-8: Collegamento della sonda della temperatura ambiente.
- Terminale 9: Collegamento sonda di sbrinamento.
- Copia porta chiave: For parameter copying.
5. Configurazione e funzionamento
5.1 Accensione
After completing all wiring, apply power to the controller. The display will show the current temperature measured by the room temperature probe.
5.2 Impostazione della temperatura
- Premere il tasto IMPOSTATO button once. The display will flash the current set temperature.
- Utilizzare il Up (▲) O Giù (▼) per regolare la temperatura desiderata.
- Premere il tasto IMPOSTATO button again to confirm and save the new setting.
5.3 Configurazione dei parametri
Advanced parameters for cooling differential, defrost cycles, fan operation, and more can be accessed and adjusted through a dedicated menu. Refer to the detailed parameter list in the full technical manual for specific codes and ranges. Parameters can also be set and copied using a copy card for quick configuration across multiple units.
6. Modalità operative
6.1 Modalità di raffreddamento
When the measured temperature rises above the set temperature plus the cooling differential, the compressor relay activates to initiate cooling. It deactivates when the temperature drops to the set point.
6.2 Modalità di sbrinamento
The controller supports various defrosting modes (e.g., timed defrost, manual defrost). During defrost, the defrost relay activates, and the compressor typically turns off. The defrost cycle duration and frequency are configurable parameters.
6.3 Fan Management
The fan output can be configured to operate continuously, only during cooling, or to turn off during defrost cycles, depending on the application requirements.
7. Manutenzione
Regular maintenance ensures the longevity and accurate operation of your temperature controller.
- Pulizia: Pulire il pannello frontale con un panno morbido, damp panno. Non usare detergenti abrasivi o solventi.
- Ispezione: Controllare periodicamente i collegamenti elettrici per verificarne la tenuta e l'eventuale presenza di segni di usura o corrosione.
- Controllo del sensore: Ensure temperature probes are clean and securely placed.
8. Risoluzione Dei Problemi
This section addresses common issues you might encounter with the ETC-3000A controller.
| Problema | Possibile causa | Soluzione |
|---|---|---|
| Il display mostra "HHH" o "LLL" | Temperature probe error (open circuit or short circuit) or out of range. | Check probe connection. Replace probe if damaged. Ensure temperature is within operating range. |
| Il controller non si accende | Nessuna alimentazione o cablaggio errato. | Verify power connection and voltage. Check wiring against diagram. |
| Compressor/Fan not activating | Incorrect temperature settings, parameter errors, or faulty wiring to the load. | Review set temperature and differential. Check relevant parameters. Inspect wiring to compressor/fan. |
| Lo sbrinamento non si avvia | Defrost parameters incorrectly set or defrost probe issue. | Check defrost cycle parameters (duration, interval). Verify defrost probe connection. |
