The electrical power consumption and cost of a control system for an air conditioning apparatus are reduced. A control system for an air conditioning apparatus mounted in a vehicle includes a plurality of vehicle-side ECUs (control units) (60a to 60d) that control devices provided in the air conditioning apparatus; and a signal control unit (50) that controls the plurality of vehicle-side ECUs (60a to 60d), wherein the plurality of vehicle-side ECUs (60a to 60d) are divided into groups each having a common ON/OFF combination for the individual operating modes of the vehicle, and the vehicle-side ECUs (60a to 60d) belonging to the same group are connected by a common signal line; and the signal control unit (50) sends ON and OFF signals depending on the operating mode of the vehicle to the signal lines (71 and 72). |
