Abstract

PURPOSE:To simplify a signal change-over device by a method wherein a single continuous electrical signal in one-to-one correspondence with the opening degree of an air mixing door is taken out, and an object of control is operated by a separately arranged change-over circuit device using the signal as an input. CONSTITUTION:The output voltage of a potentiometer 3 in a signal change-over device 2 inerlocked with an air mixing door 1 is fed to comparators 24 (24a-24d) and amplifiers 25 (25a, 25b). The comparators 24 compare the input voltage with reference voltages Vc, and generate an output ''1'' or ''0'' according to the comparison results; the amplifiers 25 amplify the difference between the input voltage and reference voltages Vc in a predetermined ratio, and generate the amplified output. The outputs of the comparators 24 are fed to switching transistors 26, for turning solenoids 27 on and off. A solenoid 27a is connected with an intake door actuator 15 and a faucet 12, while n solenoids 27b and 27c are connected with a diverter door actuator 17.
