Priority order of the water-temperature-setting-input-signal sources
Water temperature can be controlled by using the signals from the four types of input sources listed below. The
setting for the item with higher priority will override the settings for the items with lower priorities. The water
temperature will be controlled according to the temperature setting in the "Target water temperature" column that
corresponds to a specific combination of the settings for the four items.
