6.3 Parameter Settings (Example)
To set the desired temperature:
- Press the SET button once. The lower display will flash, showing the current set temperature.
- Use the UP or DOWN buttons to adjust the temperature to your desired value.
- Press the SET button again to confirm and save the setting.
For advanced parameter settings (e.g., defrost interval, fan delay, alarm thresholds), refer to the detailed parameter table in the full product manual (if available) or contact Elitech support for specific codes and ranges.
7. Maintenance
7.1 Cleaning
Regularly clean the surface of the controller with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing. Ensure no liquid enters the unit.
7.2 Sensor Check
Periodically inspect the temperature sensors for any physical damage or corrosion. Ensure they are securely connected and positioned correctly for accurate readings.
7.3 Electrical Connections
Occasionally check all electrical connections to ensure they are tight and free from signs of overheating or loose wiring. Disconnect power before performing any checks.
8. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Controller not powering on | No power supply; Loose wiring; Blown fuse. | Check power source; Verify wiring connections; Inspect and replace fuse if necessary. |
| Incorrect temperature reading | Faulty sensor; Sensor not properly installed; Sensor cable damage. | Check sensor connection and placement; Replace sensor if faulty; Inspect sensor cable for damage. |
| Cooling/Defrosting not activating | Incorrect parameter settings; Relay failure; Wiring issue to load. | Review and adjust set parameters; Check relay functionality; Verify wiring to cooling/defrosting unit. |
| Alarm continuously active | Temperature out of set range; Sensor failure; Alarm parameter misconfiguration. | Check actual temperature vs. set limits; Verify sensor operation; Adjust alarm parameters. |
