Abstract
A decentralization type control apparatus for an air-conditioning or a refrigerating apparatus comprising a plurality of terminal control units and a central control unit for controlling the plurality of terminal control units. Each of the terminal control units is provided with a monitoring and controlling section for monitoring operations of the central control unit, a first memory part which stores information output from the central control unit through the monitoring and controlling section and information input into the terminal control unit itself, a second memory part storing a control program for a load, a control part for controlling the air conditioning or refrigerating apparatus by the information stored in the memory parts, and an output part generating an alarm to the outside, wherein when a fault in the central control unit is detected by the monitoring and controlling section, the terminal control unit solely takes over operations to control the air-conditioning or refrigerating apparatus and generates from the output part an alarm informing the fault of the central control unit.
