The process of S115 is executed by the function of the determination unit 14.

When the user U _i moves from the second area to the first area (S115: Yes), the processor 5 _{associates with the user ID of the user U i} and stores the control target value in the user control target value storage table 54. Read Ai (S116).
Then, the processor 5 corrects the read control target value Ai based on the temperature difference ΔT (ΔT = T1-T2) inside and outside the building 20 (S117).
The process of S117 is executed by the function of the correction unit 15.

Next, when the variable i has not reached N (S118: No), the processor 5 adds 1 to the variable i (S119) and returns to S114.
On the other hand, if the variable i has reached N (S118: Yes), the processor 5, the user (setting target that satisfies a predetermined condition from the location identified in S111 the user _(U 1 ~U _N) Person) is selected (S120). The process of S120 is executed by the function of the selection unit 16.

Next, the processor 5 calculates the average value (may be the median value or the mode value) of the corrected control target values of the set target person selected in S120 (S121).
Then, the processor 5 sets the operation parameter of the air conditioner 30 in the first area in the first schedule based on the average value calculated in S121 (S122), and returns to the flow of FIG.

When the processing of S103 or S104 is completed, the processor 5 waits if it is not before the predetermined time from the start time of the first schedule (S105: No), and before the predetermined time from the start time of the first schedule. In the case of (S105: Yes), the operation parameters set by S103 or S104 are transmitted to the air conditioner 30 in the first area via the communication interface 7 (S106).
As a result, the operation of the air conditioner 30 according to the operation parameters set in S103 or S104 can be started before the start of the first schedule in the first area.
