PURPOSE:To provide the safety of selecting in shifting to a selected operation mode by designating one operation command mode of a plurality of operation command modes by operation mode setting means, and selectively outputting a plurality of control commands for controlling the unit to be controlled by the designated mode. CONSTITUTION:Selection data DS1 of parallel data to be input through the 4-bit signal line L1 of a rotary switch S1 and 1-bit signal line L2 of an operation mode changeover switch SW is input to the input port P of a microcomputer 33 as operation mode selection data DS2 of serial data via a non-inverting buffer 32, and the microcomputer 33 outputs a switching control signal S. When the switch SW is a normal operation mode, the state of the switch S1 is set to indoor number-of-units data. When the switch SW is an inspection operation mode, the state of the switch S1 is input as inspection operation mode number data of an outdoor unit, thereby easily designating a selecting operation. |
