Unit Address Conflict (Factory Setting) / Auto Address Not Possible

Mitsubishi Electric · FR-D700 Inverter

Was bedeutet E112 ?

One or more units (indoor or outdoor) are still addressed at 48 or 49 (factory setting). This prevents auto-addressing, which is only possible on a single KX2 system, if one or more units (either indoor or outdoor) are not set at 49.

Häufige Ursachen

  • Unit address is set to a factory default value that conflicts with other units.
  • Automatic address assignment failed due to network congestion or interference.
  • Conflicting unit addresses detected on the system.
  • Master controller unable to assign a unique address.
  • Address setting switch (DIP switch) incorrectly configured.
