The description references closing the faceplate to turn on and off. Does this mean that it doesn't function with the faceplate closed?

Mike, thank you for your question. closing the faceplate does not disable the timer—in fact, the faceplate itself functions as an ON/OFF switch when closed. So yes, the timer does function with the faceplate closed, and pressing the closed door acts as a manual override to turn the connected device on or off. This design helps maintain a clean look while still allowing manual control.
