First, the data of the outside air temperature 6 and the amount of solar radiation 7, which are the measured external information, are calculated by the parallel processing of the set value comparison / determination processing steps S2 to S4 and steps S5 to S6. Regarding the outside air temperature 6, whether the outside air temperature is equal to or higher than the set upper limit value (step S2), is not equal to or higher than the set upper limit value (step S2: NO), is equal to or higher than the set intermediate value (step S3), and the set intermediate value. If it is not greater than or equal to the value (step S3: NO), it is determined whether it is greater than or equal to the set lower limit value (step S4). On the other hand, for the solar radiation amount 7, it is determined whether the actual solar radiation amount is equal to or more than the set upper limit value (step S5), and if it is not equal to or more than the set upper limit value (step S5: N
O), it is determined whether or not the actual solar radiation amount is equal to or more than the set lower limit value (step S6).

As the calculation result, the measured outside air temperature determination result X
(Step S7) and the actual solar radiation amount determination result Y (step S8) are stored. Next, referring to the state matrix information 22 set on the roll screen / blind control setting screen (see FIG. 2) (step S10), X, Y
As a determination result, a corresponding pattern is selected from the control states of 12 patterns (step S9). After selection of the determination result, for example, the output time of the selection result is determined based on information from the setting control cycle in minutes (step S12) (step S1).
1). This setting control time is set by the control cycle of the roll screen / blind control setting screen (see FIG. 2) described above (step S12). After the output time is determined, the current control mode state is confirmed (step S14). If the control mode state confirmation confirms that it is prohibited, the control process ends (step S15). If it is permitted, the roll screen / blind 8 is turned on or off (step S14), and then the control is ended (step S15).

As described above, in this particular embodiment, the control construction is made to have the operator's side selection priority based on the actual measurement information of the outside air temperature 6 and the amount of solar radiation 7 and the preset parameters, which is suitable for the operability.
