PURPOSE:To prevent hot-water from being fed in a bathtub undesirably when residual water still remains in the bathtub. CONSTITUTION:When an automatic switch is turned on, it is judged whether residual water remains in a bathtub or not (S10 and S11). When residual water remains, a message is output (S13), and when a response switch is turned on within a specified period of time, the amount of residual water is calculated (S14, S15 and S16) and hot-water is fed additionally. When the response switch is not turned on, hot-water feed is not carried out. |
