5. Подешавање и инсталација
5.1 Монтажа
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- Обезбедите одговарајућу вентилацију око јединице.
- 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 Ожичење
УПОЗОРЕЊЕ: Ensure power is disconnected before wiring.
- Напајање: Connect the main power supply (L and N) to the designated terminals on the controller.
- Сензор температуре: 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.
- Излаз вентилатора: 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. Упутство за употребу
6.1 Укључивање/искључивање
- 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 Viewинг температуре
The current measured temperature is continuously displayed on the front panel.
6.3 Подешавање параметара
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:
- Притисните и држите СЕТ/ОК button for 3-5 seconds to enter parameter setting mode.
- Користите UP и ДОВН buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- Притисните СЕТ/ОК да view вредност изабраног параметра.
- Користите UP и ДОВН дугмад за подешавање вредности.
- Притисните СЕТ/ОК again to confirm the new value and move to the next parameter, or press and hold СЕТ/ОК to save all changes and exit the setting mode.
Common parameters include:
- Set Point (SP): Жељена температура.
- 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. Одржавање
7.1 Чишћење
- Regularly clean the front panel with a soft, damp тканина. Немојте користити абразивна средства за чишћење или раствараче.
- 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.
