• Egg Turning (Right): Connect one wire of the right egg-turning motor to terminal 15 (COM) and the other to terminal 18 (RIGHT). (Max 1A/250V AC)
• Humidificador: Connect one wire of the humidifier to terminal 15 (COM) and the other to terminal 19 (WET). (Max 1A/250V AC)
• Lamp (Illumination): Connect one wire of the lamp to terminal 15 (COM) and the other to terminal 20 (LAMP). (Max 1A/250V AC, total illumination load ≤ 100W)
• Auxiliary Heater (HEAT2): Connect the auxiliary heater to terminals 21 and 22. (Max 10A/220Vac, total heater load ≤ 1500W)
• Main Heater (HEAT1): Connect the main heater to terminals 23 and 24. (Max 10A/220Vac, total heater load ≤ 1500W)

Warning: Ensure all connections are secure and correctly matched to avoid damage to the controller or connected devices. Consult a qualified electrician if you are unsure about any wiring steps.

6. Instrucións de funcionamento

The ZL-7918A controller is designed for intuitive operation. The front panel features a digital display and four control buttons: SET, UP, DOWN, and ENTER.

6.1. Acendido/apagado

• To power on, ensure all wiring is complete and secure, then connect the controller to the AC 100~240V power supply.
• To power off, disconnect the controller from the power supply.

6.2. Setting Temperature and Humidity

1. Preme o SET button once to enter the temperature setting mode. The temperature SV (Set Value) will flash.
2. Usa o UP e ABAIXO botóns para axustar a temperatura desexada.
3. Preme ENTRAR to confirm the temperature setting and move to humidity setting mode. The humidity SV will flash.
4. Usa o UP e ABAIXO buttons to adjust the desired humidity.
5. Preme ENTRAR again to confirm the humidity setting and exit the setting mode.

6.3. Advanced Settings (Egg Turning, Ventilation, Illumination)

To access advanced settings for egg turning, ventilation, and illumination, typically a long press of the SET button or a combination of buttons is required. Refer to the full user manual (if provided separately) for specific parameter codes and adjustment procedures. The general parameters are:

• Egg-Turning Control: Period (1~999 minutes), Turning Time (0~999 seconds), Turning Times (0~999 times).
• Control de ventilación: Period (1~999 minutes), Ventilating Time (0~999 seconds).
• Control de iluminación: Period (1~999 minutes), Illuminating Time (0~999 seconds).

6.4. Hatching Day Record

The controller can record hatching days up to a maximum of 99 days. The method to reset or view this record will be detailed in the comprehensive manual.

7. Mantemento

Regular maintenance ensures the longevity and accuracy of your ZL-7918A controller.

• Limpeza: Wipe the controller's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Coidados do sensor: Keep the temperature and humidity sensors clean and free from dust or debris. Avoid submerging them in water or exposing them to extreme physical shock.
• Condicións ambientais: Operate the controller within the specified environment: -10~45℃ and <90%RH without dew. Extreme conditions can affect performance and lifespan.

8 Solución de problemas

If you encounter issues with your ZL-7918A controller, try the following troubleshooting steps:

• Sen enerxía: Check the power supply connection and ensure the outlet is functional. Verify the power wiring to terminals 13 and 14.
• Lecturas incorrectas: Ensure sensors are correctly connected to their respective terminals (1-4 for humidity, 5-6 for temperature). Check for any physical damage or obstruction to the sensors.
• Outputs Not Activating: Verify the wiring for the specific output (heater, fan, etc.) to terminals 15-24. Check the set parameters for temperature, humidity, and timing functions to ensure they are within the desired range and trigger conditions.
• Activouse a alarma: Check the current temperature and humidity readings against the set alarm thresholds. Address the environmental condition causing the alarm.
• Problemas de visualización: If the display is erratic or blank, power cycle the device. If the problem persists, contact support.

9. Consellos de usuario

• Colocación do sensor: Position the temperature and humidity sensors in a location that accurately reflects the conditions within your incubator or climate chamber, away from direct heat sources or airflow.
• Calibración: While the controller is factory calibrated, if you suspect inaccuracies, consider using a trusted external thermometer/hygrometer to verify readings. Some advanced controllers may offer calibration options (refer to the full manual).
• Estabilidade de potencia: Use a stable power source. Fluctuations can affect the controller's performance and lifespan.
• Seguimento periódico: Even with automatic control, periodic manual checks of temperature and humidity are recommended, especially during critical periods like hatching.
