になる。fA degree, occupancy rate, etc.). However, if there is a drift in each sensor itself or in the attached analog circuitry, it will indicate other different values. As an example, Fig. 2 shows a graph of temperature vs. output voltage in the case of a temperature sensor circuit, and to explain this, the sensor output So that has drifted at temperature T is △ with respect to the normally adjusted sensor output 80. There will be a difference in output voltage by V. As shown in Figure 3, the output value of each vehicle's air conditioner is divided into those that are within the allowable deviation dV from the standard range value (in this example, all other data except Vn-t) and those that are outside the range. The control command unit 7 uses the average value Vale of the moe as a control reference value, and uses the difference between the control group **va, te and each output value as each correction value. This is transmitted via the communication section 6, information transmission line 8, and communication section 5 to each air! Transmit at 45N position. The control section 3 of each air conditioner corrects the sensor output according to this correction value using a digital circuit section, and then controls the operation of the heating/cooling bomb cycle.
