ABSTRACT:
An automatic air-conditioning apparatus, especially suitable for air-conditioning of an automotive vehicle, comprises a microcomputer controlling the air-conditioning operation and a temperature display element selectively displaying an internal air temperature of the vehicle compartment sensed by an air temperature sensor and a temperature setting set by a temperature setting unit. The temperature display element displays normally the internal air temperature but displays the temperature setting for a predetermined period of time only when the temperature setting unit is manipulated. In the main control flow including the steps of air-conditioning control and temperature display stored in the microcomputer, an interrupt routine is periodically run for the purpose of analog data processing requiring a relatively long period of time, so that the microcomputer can efficiently carry out other controls.
