Auto Addressing Conflict / Factory Address Setting Error

Mitsubishi Electric · R410A Systems

Hva betyr E112 ?

During an attempt to auto-address units, one or more indoor or outdoor units are either still set to a factory default address (48 or 49) or not set to 49, preventing successful auto-addressing. Auto-addressing is only supported on single KX2 systems.

Vanlige årsaker

  • Multiple units configured with the same address.
  • Factory-set address conflicts with system settings.
  • Auto-addressing function failed to assign unique IDs.
  • Interference during the auto-addressing process.
