In essence, it’s a wall-mounted electronic shower remote with a one-button pause control. DTV Prompt works with up to two shower heads or faucets, letting users toggle between one or the other with a button push.
Before getting into the shower, the system’s “warm-up and pause” feature lets a user select the desired temperature. As soon as the water heats up to that level, it pauses the flow, awaiting a touch to begin showering, saving water in the meantime.
Further water and energy savings are possible with a countdown timer that can be set from four to 12 minutes, warning the user with a beep when there are two minutes and one minute left.
The controller, available in four different finishes, can be installed up to 20 feet away from the valves that control the water flow and temperature.
The DTV Prompt, priced at $187 for the controller and $455 for the thermostatic valve (plus installation), is a lower-cost addition to the Kohler DTV (Digital Thermostatic Valve) system. It was first introduced in 2006 with a $2,000 touchscreen shower controller that seemed modern at the time.
