Abstract

PURPOSE: To gain a highly sensible and stable hot water control unit by doubly differenciating the differential output for the hot water temperature change to make it control signals.
CONSTITUTION: A potential D, which is the partial voltage of DC source 14 through the serial circuit of a resister 15, a variable resistor for temperature setting use 16 and a negative characteristic temperature sensitive resister element 7, and the reference potential E are compared and amplified through an operational amplifier 17 to constitute the differential circuit 11 through the reistance 18, 19, 20. The proportional differential output according to the hot water change is reversely put out and doubly differentiated through the differential circuit 12 consisting of a resister 26 and a capacitor 27, further put into an integration circuit 13 consisting of an operational amplifier 22, resisters 24, 28 and a capacitor 25 to be put out into the gas valve coil 5.
