Image for operating a water heater

Abstract

This image is related to item selection for setting up a water heater. Selecting up or down changes the position and display content of the item selection section, allowing the operator to specify the item they want to select. The scroll display section indicates the vertical position of the item currently selected by the operator in the item selection section, and the direction display section indicates the directions in which the operator can operate. For example, if there are items that can be selected downward in addition to the items displayed on the screen, the direction display section is displayed at the bottom of the scroll display section; if there are no items that can be selected downward in addition to the items displayed on the screen and operation is only possible upward, the direction display section is displayed at the top of the scroll display section.
