5. Configuração e instalação
5.1 Montagem
- Choose a suitable location for mounting the controller, away from direct heat sources, moisture, and vibrations.
- Assegure-se de que haja ventilação adequada ao redor da unidade.
- 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 fios
AVISO: Certifique-se de que a energia esteja desligada antes de fazer a fiação.
- Fonte de energia: Connect the main power supply (L and N) to the designated terminals on the controller.
- Sensor de temperatura: 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.
- Saída do ventilador: 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. Instruções de operação
6.1 Ligar/Desligar
- 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 Viewtemperatura ing
The current measured temperature is continuously displayed on the front panel.
6.3 Parâmetros de configuração
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:
- Pressione e segure o DEFINIR / OK button for 3-5 seconds to enter parameter setting mode.
- Use o UP e ABAIXO buttons to navigate through the parameter codes (e.g., F1, F2, P1, P2).
- Imprensa DEFINIR / OK para view o valor do parâmetro selecionado.
- Use o UP e ABAIXO botões para ajustar o valor.
- Imprensa DEFINIR / OK again to confirm the new value and move to the next parameter, or press and hold DEFINIR / OK to save all changes and exit the setting mode.
Os parâmetros comuns incluem:
- Ponto de ajuste (PA): A temperatura desejada.
- 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. Manutenção
7.1 Limpeza
- Regularly clean the front panel with a soft, damp pano. Não use produtos de limpeza abrasivos ou solventes.
- Certifique-se de que as aberturas de ventilação estejam livres de poeira e detritos para evitar o superaquecimento.
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. Solução De Problemas
| Problema | Possível causa | Solução |
|---|---|---|
| Display shows "EE" or "HH" | Erro no sensor ou temperatura fora da faixa ideal. | Check sensor connection and wiring. Replace sensor if damaged. Ensure temperature is within operating range. |
