Image: Diagram illustrating the connection of the Zuomeng HY-110 controller to a window AC unit. It shows the room sensor, fins sensor, heater cable, and power cable connections. The fins sensor is inserted into the AC unit's cooling pipes.

  1. Mount the Controller: Choose a suitable location inside your walk-in cold room, away from direct moisture. Use the provided mounting kit to securely attach the controller to a wall.
  2. Install the Room Sensor: Place the room sensor in a central location within the cold room, ensuring it is not directly exposed to the AC airflow or any heat sources. This sensor measures the ambient temperature of the cold room.
  3. Install the Fins Sensor: Carefully insert the fins sensor into the cooling fins of your window AC unit. Refer to the diagram for proper placement, typically between the 2nd cooling pipe and the bottom cooling pipe. This sensor monitors the temperature of the AC evaporator coil to prevent icing.
  4. Connect the Heater Cable: Connect the heater cable to the designated port on the controller. The other end of the heater cable should be positioned near the AC unit's fins, as instructed, to assist in defrosting if ice buildup is detected.
  5. Connect AC Unit Power: Plug your window AC unit into the power outlet on the Zuomeng HY-110 controller. Then, plug the controller's power cable into a standard AC120V~240V wall outlet.
  6. Initial Power On: Once all connections are secure, power on the controller. The display should illuminate.

6. Operating Instructions

The controller's interface is designed for straightforward operation.

  • Power On/Off: The unit powers on automatically when connected to an electrical outlet.
  • Temperature Display: The LCD shows the current room temperature (ROOM SET) and the AC fin temperature (FINS SET).
  • Setting Temperature:
    1. Press the SET button to enter temperature setting mode.
    2. Use the Up (▲) and Down (▼) arrows to adjust the desired room temperature.
    3. Press SET again to confirm and exit.
  • Fahrenheit/Celsius Toggle: Press the F/C button to switch between Fahrenheit and Celsius display modes.
  • Heater Delay: The "HEATER DELAY" display indicates the delay time before the heater activates to prevent icing on the AC fins. This is an automatic function.
  • Automatic Operation: Once the desired temperature is set, the controller will automatically manage the AC unit and heater to maintain the set temperature and prevent ice formation.

7. Maintenance

  • Cleaning: Periodically wipe the controller's exterior with a soft, dry cloth. Do not use abrasive cleaners or solvents.
  • Sensor Check: Ensure the room and fins sensors are clean and free from obstructions. Verify their placement periodically.
  • Cable Inspection: Regularly inspect all cables for any signs of wear, damage, or loose connections.
  • AC Unit Maintenance: Follow the maintenance schedule for your window AC unit, including cleaning filters and coils, as this impacts the efficiency of the cold room.

8. Troubleshooting

ProblemPossible CauseSolution
Controller display is off.No power supply.Check if the power cable is securely plugged into the wall outlet and the controller. Verify the outlet has power.
AC unit not turning on/off as expected.Incorrect temperature setting; AC unit not plugged into controller; AC unit malfunction.Verify the set temperature is appropriate. Ensure the AC unit is plugged into the controller's output. Check if the AC unit operates independently.
Temperature in cold room is not stable.Room sensor improperly placed; poor insulation of cold room; AC unit undersized.Relocate the room sensor away from direct airflow. Improve cold room insulation. Consider a larger AC unit if necessary.
AC unit fins are icing up.Fins sensor improperly placed or faulty; heater cable not working.Ensure the fins sensor is correctly inserted into the AC coils. Check the heater cable connection.
