Abstract

PURPOSE:To realize the automatic operation for a titled controller from a starting point, by expressing the relation between the temperature of a cooled water inlet and the opening in a function, deciding automatically the span of the vane opening in accordance with the temperature of the cooled water inlet and controlling the vane within the span. CONSTITUTION:The temperature of cooled water is converted by a resistance- voltage converter 10 and then compared by a temperature controller 12. Then a vane motor 6 is driven in the increasing direction of the vane opening through an AND gate 14, a clock pulse producing circuit 13, a 1-step increase opening setting circuit 17 and a vane motor controlling circuit 21 in the case of set value Ts<variable value TP. While in the case of Ts>Tp, the motor 6 decreases the vane opening in the same way. A function setting circuit 16 converts the output of the converter into the voltage and delivers it. The maximum and minimum opening setting circuits 19 and 20 set the vane at a certain opening to the inlet temperature. On the other hand, the output of the circuit 13 drives the motor 6 in the increasing and decreasing direction. In this case, the step width is set by the output of the circuit 16.
