4) Deletion of information on address not existing
• Deletion of information on address not existing ................................................... 5
This operation is to be conducted when “6607” error (No ACK error) is displayed on the remote controller due to the
setting error during test run, or due to the old memory remaining at the time of the modification of group composition,
and the address with no corresponding units will be deleted.
Note: The connection information (connection between indoor unit and outdoor unit) on the refrigerant system
cannot be deleted.
