The U is a connected shower by Moen. This is the two function digital controller for the shower.
You can control water temperature, set timers for auto-shower shutoff and even save presets.
The companion app for both iOS and Android smartphones gives you the same controls and customizations as the U's digital controller.
A handy feature for kids is a timer that automatically shuts the shower off after a set time.
The digital controller connects to a digital value that is installed on your shower's water pipes.
