This operation is to be conducted when “6607” error (No ACK error) is displayed on the remote controller caused by
the miss setting at test run, or due to the old memory remained at the alteration/modification of group composition,
and the address not existing will be deleted.
Note : The connection information (connection between indoor unit and outdoor unit) on the refrigerant system can
