5. Opstelling en installering
5.1 Montering
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- Verseker voldoende ventilasie rondom die eenheid.
- Cut a rectangular opening in the panel according to the controller's dimensions (refer to the product diagram for exact measurements).
- Insert the controller into the opening and secure it using the provided mounting clips.
5.2 Bedrading
WAARSKUWING: Maak seker dat die krag afgeskakel is voor die bedrading.
- Kragtoevoer: Connect the main power supply (L and N) to the designated terminals on the controller.
- Temperatuursensor: 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.
- Compressor Output: Connect the compressor's power line to the compressor relay output terminals.
- Defrost Heater Output: Connect the defrost heater's power line to the defrost relay output terminals.
- 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. Bedryfsinstruksies
6.1 Krag aan/af
- To power on, connect the main power supply. The display will show the current temperature.
- To power off, disconnect the main power supply.
6.2 Viewtemperatuur
The current measured temperature is continuously displayed on the front panel.
6.3 Stel parameters
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:
- Druk en hou die SET / OK button for 3-5 seconds to enter parameter setting mode.
- Gebruik die UP en AF buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- Druk SET / OK aan view die waarde van die geselekteerde parameter.
- Gebruik die UP en AF knoppies om die waarde aan te pas.
- Druk 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): The desired temperature.
- 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. Onderhoud
7.1 Skoonmaak
- Regularly clean the front panel with a soft, damp lap. Moenie skuur skoonmaakmiddels of oplosmiddels gebruik nie.
- Ensure the ventilation openings are free from dust and debris to prevent overheating.
7.2 Sensor Check
- Periodically inspect the temperature sensor and its wiring for any damage or corrosion.
- Ensure the sensor is securely placed and making proper contact.
8. Probleemoplossing
| Probleem | Moontlike oorsaak | Oplossing |
|---|---|---|
| Display shows "EE" or "HH" | Sensor error or temperature out of range. | Check sensor connection and wiring. Replace sensor if damaged. Ensure temperature is within operating range. |
| Beheerder word nie aangeskakel nie | Geen kragtoevoer of verkeerde bedrading. | Verifieer kragaansluiting en volumetage. Check wiring according to diagram. |
| Kompressor loop nie | Temperature not reaching set point, compressor delay, or wiring issue. | Check set point and differential. Wait for compressor delay. Verify compressor wiring. |
| Onakkurate temperatuurlesing | Sensor placement, sensor damage, or calibration needed. | Relocate sensor to a representative area. Check sensor for damage. Refer to manual for calibration procedure if available. |
