Some rv's have more than one water pump switch. Much like some lights in your house have 2 switches. My kitchen has one switch just inside the back door and the second at the doorway to the living room. Both turn the ceiling light on and off. What your control panel is saying is that depending on the model of rv it may, or may not, have the second switch installed.
