1. A valve assembly configured to be positioned within a wall including an access opening, the valve assembly comprising:
- a valve configured to be coupled to a water source, the valve including a movable valve member configured to control the flow of water therethrough;
an electric actuator operably coupled to the valve and configured to move the valve member;
a cover configured to be supported by the wall to conceal the access opening;
a sensor configured to detect the position of the cover relative to the access opening and generate a signal indicative thereof; and
a controller in electrical communication with the sensor and configured to selectively disable operation of the electric actuator in response to the signal from the sensor indicative of the position of the cover relative to the access opening.

10. A valve assembly configured to be positioned within a wall behind an access opening, the valve assembly comprising:
-
a first valve configured to be coupled to a first fluid source, the first valve including a movable valve member configured to control the flow of a first fluid therethrough; a first actuator operably coupled to the first valve and configured to move the valve member of the first valve in an automatic mode of operation; a first manual handle accessible through the access opening and operably coupled to the first valve, the first manual handle being configured to move the valve member of the first valve in a manual mode of operation; a cover configured to be supported by the wall to conceal the first manual handle; a cover sensor configured to detect the position of the cover relative to the access opening; and a controller in communication with the cover sensor and configured to operate in the manual mode of operation when the cover sensor does not detect the cover. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
