It is also possible to cancel the setting of 12 and set the sub-temperature to the same temperature as the main temperature.

Also, since the same operation as above is performed at the time of engine starting operation, that is, at the time of initial setting, the setting of the secondary temperature operating portion is canceled, and the secondary temperature may be set to the same temperature as the main temperature. It goes without saying that it is necessary to select and decide in advance which kind of function in any case.

With the above configuration, the circuits of the main and sub temperature setting operation parts 11 and 12 of the driver's seat and the passenger's seat are controlled by the main temperature control circuit 21 and the sub temperature control circuit 22 shown in FIG. It is output from 23 to the actuator on the vehicle side.

That is, when the main temperature setting operation unit 11 is operated, the set temperature is displayed on the main temperature display unit 15, and the main temperature control circuit 21 to the sub temperature control circuit 22 are operated.
The control signal 19 is output to the sub-temperature display unit 16 and the sub-temperature display unit 16 is controlled. This will be described with reference to the flowchart of FIG.

(Step: P1) Main temperature control circuit 21,

(Step: P6) Main temperature setting operation unit 11
If the set temperature of is negative, the process proceeds to step: P6A to decrease the temperature.

(Step: P7) Output the slave temperature control signal and return to Step: P3 (For example, if T = 0, there is no temperature difference between the main temperature display and the slave temperature display, and T = X.
If "X is the set temperature difference", the temperature difference is maintained).

(Step: P8) Secondary temperature setting operation unit 12
If the set temperature operated by is positive, step: P8
Proceed to A and increase the temperature.

(Step: P9) Secondary temperature setting operation unit 12
