PURPOSE:To obtain a safe mixing control device of hot water and water that does not cause use of boiling water by providing a priority circuit that energizes a water side valve prior to a hot water side valve when starting taking out of hot water. CONSTITUTION:When starting taking out of hot water, a signal to stop the second driving device 8 is outputted from a priority circuit 17. Then, deviation of flow rate is detected basing on the signal of the first quantity of hot water setting device 13 in preference to the signal of the second quantity of hot water setting device 14 set by user, and the first driving device 7 is energized through the first amount of energizing setting device 18 and only water side is opened and water is let flow to a set value of the first quantity of hot water setting device 13. Then the priority circuit 17 energizes the second driving device 8 basing on the signal of a temperature deviation detecting device 16 that detects that the set water quantity is arrived at, and opens the hot water side. That is, water is let flow first, and hot water side is opened later to adjust temperature of hot water. Thus, danger of using boiling water by a user can be prevented. |
