Abstract

PURPOSE:To shorten the time required to stabilize hot water temp. in the condition that a mixing valve is driven at the high speed by setting the amount of energization of a drive means for a mixing valve at a fixed amount at the time of the change in the flow amount. CONSTITUTION:At the time of the change in the flow amount the change amount is detected by a detector 9 for the flow amount and when the change amount is equal to a set amount or more, the width of a drive pulse (the amount of energization) is set to a prescribed constant pulse width and when equal to the set amount or less, the width of the drive pulse is to be set to the pulse width which is proportional to the square of a deviation by a set means 14 for the amount of energization. When the change amount is therefore large at the time of the change in the flow amount, the high speed operation of control for the opening of a mixing valve 10 causes the flow amount at the water side to increase rapidly to control the rise in hot water temp. if the flow amount changes from large to small, thereby the temp. of mixed hot water can be stabilized rapidly to a set temperature.
