ものである。In FIG. 1, reference numeral 1 is a sensor such as temperature or humidity, and the signal of this sensor 1 is output to a signal processing circuit 7 via a detection circuit 2. The load drive circuit 4 drives the load 5 by the output signal of the signal processing circuit 7. Display device 6
Is a signal output when the signal processing circuit 7 determines that the input signal of the detection circuit 2 is a set value (detection acceptance signal)
Lights up. The control operation will be described with reference to FIG. At 8 the signal from the detection circuit 2 is taken, and at 9 it is determined whether or not the signal is the set value. Here, if the input signal is not the set value, the signal from the detection circuit 7 is fetched again, and if the input signal is the set value, the process moves to 10 and an output indicating that the detection circuit 2 has detected the signal A signal is output from the signal processing circuit 7, and the display device 6 is turned on. Subsequently, the process proceeds to 11 predetermined processes. The processing here means, for example, if the sensor detects a temperature of 50 ° C., it delays a time 3T 50 which is three times the time T 50 from the start of operation to the detection, and the output of a plurality of detection circuits. It means selecting a load driven by a signal. After processing at 11, then 12
