Operation mode setting apparatus for air conditioner

This invention aims to facilitate setting and modifications of characteristic data for microcomputers used for control of various types of air conditioner. A control device for the air conditioner comprises a microcomputer having a first ROM for storing a program for controlling operations of a compressor and a blower, a RAM for storing present data and various data associated with the operations and a CPU for executing the program. A second ROM is provided in the control device for storing specific data representing capacity of the components such as compressors and a blower, functions of the air conditioner, exclusive cooling or cooling/heating and so on.
