<p>PURPOSE:To dispense with alteration of an air-conditioning control system as a whole even when the number of air-conditioning units changes, by a method wherein a plurality of control apparatuses are provided on multistage stories, a state of a discrete apparatus to be controlled is displayed in both of the control apparatuses on a plurality of stories and this apparatus to be controlled is operated from both of them. CONSTITUTION:An operation display part 19 displays states of operations of air-conditioning units 1 and 2 and a handy remote control 3 which local centralized control parts 4 and 14 control. An operation display part 20 displays the respective states of operations of air-conditioning blocks 6 and 16, transmission converting parts 7 and 17 and a transmission control part 9 by lighting. A communication means 21 executes transmission of information on the states of operations or reception of control signals between apparatuses, e.g. between a transmission control part 8 and the transmission converting parts 7 and 17 and between the local centralized control parts 4 and 14 and air-conditioning units 6 and 16.
