HOT WATER AND WATER MIXING CONTROL DEVICE

摘要

PURPOSE:To always supply hot water at a set temperature stably by quickly operating driving means to move a mixing valve to the optimum position. CONSTITUTION:A deviation signal obtained by deviation detecting means 17 is compared with a set value of the first deviation setting means 18. When the deviation signal is larger, urging amount setting means 22 is set at the first urging amount, which is output to driving means 13. The driving means 13 is urged by the first urging amount to move a mixing valve at full speed to the optimum position through a cam. When the temperature deviation becomes smaller, the urging amount setting means 22 is set at the second urging amount, which is output to the driving means 13.
