PURPOSE:To obtain a centralized controller for a plurality of display cases, etc., having extensibility in an alarm and a control when operations of the plurality of the cases are centralizedly controlled. CONSTITUTION:A microcomputer for a terminal side controller 6 generates data regarding an operating state of a display case S, etc., which includes class data for identifying itself based on an output of a sensor and alarm content data of a predetermined bit train corresponding to malfunction contents. The microcomputer specifies the malfunction content by bits corresponding to the content of the malfunction in alarm content data if the malfunction occurs and necessity of an alarm takes place. A centralized controller 2 receives data regarding the operating state of the case S, etc. The microcomputer of the controller 2 executes a predetermined alarm operation based on the class data and the content data in the data regarding the operating state of the case S, etc. |
