PROBLEM TO BE SOLVED: To solve the problem in which the number of various sensors needed to control an air conditioner needs to be reduced so as to use a limited number of A/D conversion circuits in a configuration in which A/D conversion circuits of a microcomputer is used to determine a limit request level of a demand signal.SOLUTION: An air conditioner is characterized in that when a data transmitter receiver which transmits and receives a control program for a microcomputer or control parameters of a storage medium is connected to an outdoor control board, the microcomputer connects a serial transmission/reception circuit to a connector, and receives and writes the control program or the control parameters to the microcomputer or storage medium, and when a demand signal transmitter transmitting a demand signal is connected to the connector, the microcomputer connects an input circuit to the connector, and receives the demand signal and controls the power consumption of the air conditioner. |
