Abstract: A controller for use in a wet environment is provided. The controller includes a manually operable input device coupled to a base housing. The manually operable input device includes a first manual input member and a second manual input member, where the second manual input member is movable relative to the first manual input member. The manually operable input device includes a sealed environment disposed at least partially within the base housing and having one or more electronic components that control at least one function of a fluid delivery device. The one or more electronic components actuate responsive to user-initiated movement of the first manual input member and user-initiated movement of the second manual input member. The first manual input member and the second manual input member are disposed at least partially outside the sealed environment.

Abstract: A controller for use in a wet environment such as an ablutionary setting includes a display for displaying information related to the operation of a fluid delivery system. The display includes a light source, a semi-transparent layer, and a touch interface configured to provide an input to the controller. The light source and the semi-transparent layer are configured such that the semi-transparent layer absorbs or reflects light transmitted towards the light source and allows light transmitted from the light source to be transmitted from the display, such that the light source appears hidden when light is not transmitted from the light source.
