<p>PURPOSE:To display a report of priority state without delay at the time of switching to priority and prevent a mistake in an operation such as setting of an unconnected remote controller. CONSTITUTION:A priority state of setting a hot water temperature is reported and displayed based on an identification result from connection identifying means 3b for identifying presence or absence of connection of a kitchen remote controller 4 and a signal from priority switching means 5e of a bathroom remote controller 5. The result is stored in a memory in identification result memory means 5d of the controller 5 and a memory in the means 3b, accessed to inform and display the priority state without delay. If the controller 4 is not connected, even if a priority operation to the controller 4 is conducted, the means 5e does not receive it, thereby eliminating a mistake of the operation.</p> |
