Abstract
PURPOSE: To simplify the wiring, by performing the transfer of data signals for the collective control and monitoring of air conditioners between the central controller and the air conditioners by cyclic transmission and receiving between the central controller and unit controllers.
CONSTITUTION: When a microcomputer 4b of the central controller 4 receives a zero point detection signal of electric source from an electric source section 4c, interruption is performed, so that the transmit-receive data designating a unit address is synchronized with the electric source, and is delivered via a transmit- receive means to control lines 7 and then to the unit controllers 5 cyclically. When a microcomputer 5b of each unit controller 5 receives a zero point detection signal of electric source from an electric source output circuit 5c, interruption is performed, so that the unit address in the data signal sent from the transmit-receive means 4a is judged by driving a transmit-receive means 5a whether it is identical, and when it is identical, it is received and a control output section 5e is driven.
