• Umidifikatur: 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. Istruzzjonijiet Operattivi

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. Power On/Off

• 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. Agħfas il- SET button once to enter the temperature setting mode. The temperature SV (Set Value) will flash.
2. Uża l- UP u 'L isfel buttuni biex taġġusta t-temperatura mixtieqa.
3. Agħfas DĦUL to confirm the temperature setting and move to humidity setting mode. The humidity SV will flash.
4. Uża l- UP u 'L isfel buttons to adjust the desired humidity.
5. Agħfas DĦUL 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).
• Kontroll tal-ventilazzjoni: Period (1~999 minutes), Ventilating Time (0~999 seconds).
• Kontroll tal-Illuminazzjoni: 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. Manutenzjoni

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

• Tindif: Wipe the controller's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no liquids enter the device.
• Kura tas-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.

• Kontroll tal-Konnessjoni: Periodically inspect all wiring connections to ensure they remain tight and free from corrosion.

8 Issolvi l-problemi

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

• Ebda Qawwa: Check the power supply connection and ensure the outlet is functional. Verify the power wiring to terminals 13 and 14.
• Qari Skorrett: 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 Mhux Attivati: 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.
• Allarm Attivat: Check the current temperature and humidity readings against the set alarm thresholds. Address the environmental condition causing the alarm.
• Kwistjonijiet tal-Wiri: If the display is erratic or blank, power cycle the device. If the problem persists, contact support.

9. Għajnuniet għall-Utenti

• Tqegħid tas-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.
• Kalibrazzjoni: 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).
• Stabbiltà tal-Enerġija: Use a stable power source. Fluctuations can affect the controller's performance and lifespan.
• Monitoraġġ Regolari: Even with automatic control, periodic manual checks of temperature and humidity are recommended, especially during critical periods like hatching.
