5.2 Ožičenje

OPOZORILO: Ensure power is disconnected before wiring.

1. Napajanje: Connect the main power supply (L and N) to the designated terminals on the controller.
2. Senzor temperature: Connect the NTC temperature sensor to the sensor input terminals. Ensure correct polarity if applicable. The sensor should be placed in the area where temperature needs to be monitored and controlled.
3. Compressor Output: Connect the compressor's power line to the compressor relay output terminals.
4. Defrost Heater Output: Connect the defrost heater's power line to the defrost relay output terminals.
5. Fan Output: Connect the evaporator fan's power line to the fan relay output terminals.

Refer to the wiring diagram printed on the side of the controller or in the specific model's manual for precise terminal connections.

6.1 Vklop/izklop

• To power on, connect the main power supply. The display will show the current temperature.
• Za izklop izključite glavno napajanje.

6.2 Viewing temperature

The current measured temperature is continuously displayed on the front panel.

6.3 Nastavitev parametrov

The controller allows adjustment of various parameters such as setpoint temperature, differential, defrost cycle, and fan operation. The exact procedure may vary slightly by model, but generally follows these steps:

1. Pritisnite in držite SET / OK button for 3-5 seconds to enter parameter setting mode.
2. Uporabite UP in DOL buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
3. Pritisnite SET / OK do view vrednost izbranega parametra.
4. Uporabite UP in DOL gumbe za nastavitev vrednosti.
5. Pritisnite SET / OK again to confirm the new value and move to the next parameter, or press and hold SET / OK to save all changes and exit the setting mode.

Common parameters include:

• Set Point (SP): Želena temperatura.
• Differential (Hy): The temperature difference between the set point and the turn-on/off temperature.
• Defrost Cycle (Id): Interval between defrost cycles.
• Defrost Duration (Ed): Length of the defrost cycle.
• Fan Control (Fc): Settings for fan operation during refrigeration and defrost.

7. Vzdrževanje

7.1 Čiščenje

• Regularly clean the front panel with a soft, damp krpo. Ne uporabljajte abrazivnih čistil ali topil.
• Ensure the ventilation openings are free from dust and debris to prevent overheating.
