Abstract
PURPOSE:To estimate the state of temp. change caused by the opening and closing of a valve and set the most suitable gain on the basis of this state by installing a computing means for test opening which sets the opening of a valve for mixing hot and cold water by means of the operation of a test switch and a computing means for test temp. computing the temp. difference between both sides. CONSTITUTION:When a test switch 11 is operated, a command means 13 for test opening sends a command signal for opening to make theta=theta1. When the detected signal thetam of a detecting means 8 for opening coincides with an output signal theta1, a computing means 15 for temp. reads the temp. T1 at that time. Then, the means 13 sends a command signal for opening to make theta=theta2. The means 15 reads the temp. T2 at that time to compute the temp. difference DELTAT=T1-T2. A gain value corresponding to the side temp. difference in gain values previously stored is sent to a velocity control means 17 as the most suitable gain value G. Thus, by carrying out test operation before actual water supply, the most suitable gain value for opening and closing valves in a piping system can be specified.
