  If there's no display on your SystemAir Controller, here's what you can check: * First, ensure that the IDU is powered on. If it isn't, power it on. * Next, power off the IDU and then verify the wired controller connection, ensuring it meets the wiring requirements. * If the connection is correct, the wired controller may be damaged and need replacement. * Lastly, a power supply failure of the IDU main PCB could be the cause, requiring replacement of the IDU main PCB.

What to do if SystemAir Controller displays error E9?

  Carol ReidAug 13, 2025
  If your SystemAir Controller displays an 'E9' error, it could indicate several issues: * A communication fault between the wired controller and the IDU. * The IDU might lack an address, or its address is duplicated. To resolve this, set a unique address for the IDU, as duplicated addresses are not permitted within the same system. * The wired controller itself may be damaged, necessitating replacement. * Alternatively, the IDU main PCB might be faulty, requiring its replacement.
