Abstract

PURPOSE: To remove hunting of a tapping temperature characteristic and to reduce the error between a set temperature and a tapping temperature by a method wherein the number of rotation of a blower is corrected and controlled by the gradient of the tapping temperature.
CONSTITUTION: A proportionally amplifying circuit 1 amplifies the difference between a signal from a temperature setting circuit 4 and a signal from a temperature detecting circuit 3 composed of resistances R4, R5 and a negative characteristic thermistor 14 of a temperature sensor. A differential circuit 12 outputs a signal proportional to the magnitude of gradient of a signal change of the temperature detecting circuit 3. The output of an addition circuit 13 is inputted in a current limiting circuit 6 through a photocoupler 15. The current limiting circuit 6 decides the number of the motor 16 of a blower and the blower supplies air to a proportional preliminary mixer. In this manner, when the differential circuit 12 detects the gradient of a tapping temperature characteristic and the number of rotation of the blower is corrected by the temperature gradient, the hunting of the tapping temperature characteristic can be removed.
