ABSTRACT:
In a case where peculiar control information which differs depending upon buildings is revised, a first memory for storing the revised information and a second memory for storing the original information before the revision are disposed, and addresses and contents are correspondingly stored in both the memories, whereupon the stored contents of both the memories are displayed on a display unit at the respectively corresponding addresses. Thus, the presence or absence of an alteration error in the case of the revision of the control information can be reliably checked.
