Further, the user can increase or decrease the set temperature on the passenger seat side by tapping the positive button 41 c and the negative button 41 b on the touch panel 16.

  Control part 12a which finished processing of Step S41 judges whether slide operation of temperature slide bar 41a was performed by touch panel 16, as shown in Drawing 7D (Step S42). When it is determined that the slide operation has been performed (step S42: YES), the control unit 12a specifies a set temperature corresponding to the slide amount of the slider (step S43). The control unit 12a stores the specified set temperature in the temporary storage unit 12b.

  When the process of step S43 is completed, or when it is determined that the slide operation of the temperature slide bar 41a is not performed (step S42: NO), the control unit 12a uses the touch panel 16 to perform the temperature slide as shown in FIG. 7E. It is determined whether or not the tap operation on the bar 41a has been performed (step S44).
