PURPOSE:To enhance the controllability in the micro-computer control of an air- conditioning system, by judging parameters indicating operating conditions at the time of the previous stopping, when an instruction of air-conditioning mode is given, so that whether a memory control mode or a new mode may be determined for the subsequent operation. CONSTITUTION:Upon a key switch 1 being turned on, the memory of an AUTO switch 7a is previously set if, for example, 2 hours have been elapsed from the release of the switch, but the state of the switch memory before that is followed when the elapsed time is within two hours. Thereafter, the control mode is continued unless an OFF switch 7b, an Lo fixing switch 7c and an Hi fixing switch 7b are turned on. Accordingly, even if no operation is made to a control panel 7 other than the turning-on of the key switch 1 upon on-boarding the car, the previous mode or the AUTO mode is automatically set, and, therefore, suction, blow-off, blast volume and room temperature are automatically controlled and a lamp is illuminated. |
