  • Graphical Glitch on Nexus:

    • Reset the controller by pressing the reset button under the screen.

    • This may restore the missing systems on the display.

  • Multiplexer Port Issue:

    • The CCPU-side port on the multiplexer may be causing the issue.

    • Move the cable from the affected systems' CPU to a different port on the multiplexer, ensuring that a cable remains connected to the CCPU1 port.

  • Check CPU-to-Multiplexer Cables:

    • Inspect the cables running from the other two systems' CPUs to the multiplexer for any loose or faulty connections.

  • CPU Functionality:

    • The CPUs are likely functioning correctly since the customer can control all AC units via the app.
