To the right, a white, louvered sensor probe with a coiled cable is visible, indicating its connection to the main unit.

2. Орнотуу жана орнотуу

Before installation, ensure the power supply is disconnected. The ZL-7816A controller requires careful wiring and sensor placement for optimal performance.

2.1 Пакеттен чыгаруу

Carefully remove the controller and its sensor from the packaging. Inspect for any visible damage.

2.2 Sensor Connection

Connect the provided temperature and humidity sensor to the designated port on the controller. Ensure a secure connection. The sensor should be placed in the environment where temperature and humidity are to be monitored and controlled, away from direct heat sources or moisture.

2.3 Power and Output Wiring

The controller operates on AC power and provides output relays for controlling external devices (e.g., heaters, humidifiers, fans). Refer to the detailed wiring diagram provided with your product for correct electrical connections. Incorrect wiring can cause damage to the device or connected equipment, and poses a safety risk. It is recommended that installation be performed by a qualified electrician.

2.4 Монтаждоо

The controller can be mounted using a Hook & Loop Fastener system or other suitable methods. Ensure it is secured in a location that allows for easy viewing of the display and access to control buttons, and is protected from excessive moisture or extreme temperatures.

3. Иштөө нускамалары

The ZL-7816A controller features a user-friendly interface for setting and monitoring environmental parameters.

3.1 Күйгүзүү/өчүрүү

Once wired correctly, connect the power supply. The LED digital display will illuminate, showing current temperature and humidity readings.

3.2 Дисплейview

• The upper display typically shows the current temperature in degrees Celsius (°C).
• The lower display typically shows the current relative humidity in percentage (%RH).
• "OUT" indicators (if present) will light up when the corresponding output relay is active, indicating that a connected device is being powered.

3.3 Параметрлерди орнотуу

To adjust the target temperature or humidity, or other operational parameters:

1. Press the 'S' (Set) button to enter the setting mode.
2. Use the 'Up' (▲) and 'Down' (▼) arrow buttons to navigate through different parameters.
3. Press 'S' again to select a parameter for editing.
4. Use the 'Up' (▲) and 'Down' (▼) arrow buttons to adjust the value.
5. Press 'S' to confirm the new value and move to the next parameter, or hold 'S' to save and exit the setting mode.

Specific parameters may include: temperature set point, humidity set point, hysteresis (differential), calibration offsets, and alarm settings. Consult the full product manual for a complete list of parameters and their functions.

4. Техникалык тейлөө

Regular maintenance ensures the longevity and accuracy of your LILYTECH ZL-7816A controller.

• Тазалоо: Дисплейди акырын сүртүп, casing жумшак, кургак чүпүрөк менен. Абразивдүү тазалагычтарды же эриткичтерди колдонбоңуз.
• Сенсорго кам көрүү: Keep the sensor probe clean and free from dust or debris. Avoid exposing the sensor directly to water or harsh chemicals.
• Байланыштары: Мезгил-мезгили менен бардык зымдарды байланыштарды текшерип туруңуз, алар бекем жана коррозиядан таза.
• Курчап турган чөйрө: Ensure the controller is operated within its specified environmental conditions (temperature, humidity) to prevent damage.

5. Кыйынчылыктарды

If you encounter issues with your ZL-7816A controller, consider the following common troubleshooting steps:

5.1 Дисплей иштебей жатат

• Электр менен камсыздоо байланышын текшериңиз.
• Электр розеткасынын иштешин текшериңиз.
• Verify internal wiring if accessible and you are qualified to do so.

5.2 Incorrect Readings

• Ensure the sensor is correctly connected and not damaged.
• Check the sensor's placement; it should be in the area to be measured, not near heat sources or drafts.
• Consider if calibration is needed (refer to the full manual for calibration procedures).

5.3 Outputs Not Activating

• Verify that the set points for temperature and humidity are correctly configured.
• Check the hysteresis (differential) settings.
• Ensure the connected external devices are functional and correctly wired to the controller's outputs.
• Confirm that the controller's output relays are not damaged (if applicable, and only if you are qualified to inspect).

For persistent issues, consult the comprehensive troubleshooting guide in the official product manual or contact technical support.

7. Колдонуучунун кеңештери

Based on common feedback for similar devices, here are some tips for using your controller:

• Туруктуу күч: Ensure a stable power supply to prevent unexpected resets or fluctuations in control.
• Сенсордун жайгашуусу: For accurate readings, place the sensor in a central location within the controlled environment, away from direct airflow from heating/cooling elements.
• Hysteresis Settings: Adjust the hysteresis (temperature/humidity differential) carefully to prevent rapid cycling of connected devices, which can reduce their lifespan. A small differential can lead to frequent switching, while a larger one might result in wider environmental fluctuations.
• Үзгүлтүксүз мониторинг: Periodically cross-reference the controller's readings with an independent, calibrated thermometer/hygrometer to ensure accuracy.
