4.2 Wiring Diagram

Proper wiring is crucial for the safe and correct operation of the incubator controller. Refer to the diagram below for connection points.

Image 3: Detailed wiring diagram for the MMUNNA XM-18 controller. This diagram illustrates connections for the lamp bulb, uniform temperature fan, Heater 1, Heater 2, Humidifier, Egg Turning Motor, and Ventilating Fan. It also shows the power input (L, N) and sensor connections (+5V, H, GND, T). Ensure all connections are secure and follow local electrical codes.

• Connect the power supply (AC 160V-240V or AC 110V, depending on your model) to the designated L and N terminals.
• Connect the temperature sensor to the 'T' and 'GND' terminals.
• Connect the humidity sensor to the 'H' and '+5V' terminals.
• Connect heating elements (Heater 1, Heater 2) to their respective output terminals.
• Connect the egg turning motor to the 'Turn Left' and 'Turn Right' terminals.
• Connect the humidifier to the 'Humidity Control' terminal.
• Connect the ventilating fan to its designated terminal.
• Connect the lamp bulb and uniform temperature fan as indicated.
• Ensure all connections are tight and insulated to prevent short circuits.

4.3 Initial Power-Up

After completing all wiring, connect the controller to a suitable power source. The digital displays will illuminate, showing the current temperature (PV TEM) and humidity (PV WET).

5. Operating Instructions

5.1 Display Overview

Image 4: Close-up of the MMUNNA XM-18 controller's front panel. The top left display shows the current temperature (PV TEM), top right shows current humidity (PV WET). The bottom left (SV) shows the set temperature, and bottom right (SV) shows the set humidity. Indicator lights for FAN, HEAT1, HEAT2, UP, DOWN, WET, and ALARM are also visible.

• PV TEM: Current measured temperature.
• PV WET: Current measured humidity.
• SV (left): Set temperature value.
• SV (right): Set humidity value.
• Indicator Lights: Indicate active functions (FAN, HEAT1, HEAT2, WET) or status (UP, DOWN, ALARM).

5.2 Setting Parameters

To adjust settings, use the SET button and the ▲ (Up) / ▼ (Down) buttons.

1. Set Temperature:
   • Press the SET button once. The SV (left) display will flash.
   • Use the ▲ / ▼ buttons to adjust the desired temperature.
   • Press OK to confirm and save the setting, or wait a few seconds for it to save automatically.
2. Set Humidity:
   • Press the SET button twice. The SV (right) display will flash.
   • Use the ▲ / ▼ buttons to adjust the desired humidity.
   • Press OK to confirm and save the setting, or wait a few seconds for it to save automatically.
3. Advanced Settings (Egg Turning, Ventilation, Alarms):
   • Press and hold the SET button for approximately 3 seconds to enter the advanced parameter settings menu.
   • Use the SET button to cycle through different parameters (e.g., F1, F2, F3...).
   • Use the ▲ / ▼ buttons to adjust the value of the selected parameter.
   • Press OK to confirm and save each setting.
   • Refer to the specific parameter codes (e.g., F1 for over-temperature alarm, F2 for egg turning cycle) in the detailed programming guide (not provided in this general manual, typically found in a more extensive manual).

5.3 Automatic Functions

• Temperature Control: The controller will automatically activate heaters (HEAT1, HEAT2) to maintain the set temperature.
• Humidity Control: The controller will activate the humidifier (WET indicator) to maintain the set humidity.
• Egg Turning: Based on the programmed cycle and duration, the egg turning motor will activate automatically.
• Ventilation: The ventilating fan will operate according to its programmed cycle and duration.
• Alarms: The ALARM indicator will illuminate and an audible alarm may sound if temperature or humidity deviates significantly from set points, or in case of other detected issues.

6. Maintenance

• Cleaning: Regularly wipe the controller's surface with a soft, dry cloth. Do not use abrasive cleaners or allow liquids to enter the device.
• Sensor Care: Keep temperature and humidity sensors clean and free from dust or debris to ensure accurate readings. Avoid bending or damaging the sensor cables.
• Connections: Periodically check all wiring connections to ensure they remain secure.
• Environment: Ensure the operating environment adheres to the specified temperature and humidity ranges to prevent damage to the controller.
