5. Maintenance

  • Cleaning the Controller: Use a soft, dry cloth to wipe the surface of the controller. Avoid abrasive cleaners or solvents. Ensure no liquid enters the device.
  • Sensor Care: Keep the thermal-alloy sensor clean and free from debris. If necessary, gently wipe the sensor tip with a damp cloth and allow it to dry completely before re-use. Avoid bending or damaging the sensor probe.
  • Storage: When not in use for extended periods, store the controller and sensor in a cool, dry place away from direct sunlight and extreme temperatures.

6. Troubleshooting

  • Controller Not Powering On:
    • Ensure the power cord is securely plugged into both the controller and a functional electrical outlet.
    • Check the circuit breaker for the outlet.
  • Devices Not Responding:
    • Verify that the devices are properly plugged into the controller's outlets.
    • Check the controller's display and app to ensure the programs are active and the outlets are set to ON.
    • Confirm the devices themselves are functional by plugging them directly into a wall outlet.
  • Inaccurate Sensor Readings:
    • Ensure the sensor probe is clean and unobstructed.
    • The sensor may require calibration. Use the AC Infinity app to access calibration settings and follow the instructions for temperature, humidity, or VPD calibration.
    • Avoid placing the sensor in direct airflow or near heat/cold sources that do not represent the general environment.
  • App Connectivity Issues:
    • Ensure your mobile device's Bluetooth and/or WiFi is enabled.
    • Verify the controller is within range of your WiFi router or mobile device for Bluetooth connection.
    • Restart the AC Infinity app and/or your mobile device.
    • If using WiFi, check your network connection and ensure the controller has been properly configured to your WiFi network.

If issues persist, please refer to the AC Infinity support resources or contact customer service.
