U3 Water Resistant Remote Control


The U3 weather-resistant remote is the perfect companion for hot tubs, pools, bathrooms, and decks, delivering reliable wireless control of electronic systems in environments that are too harsh for standard remotes.

The durable remote floats if dropped in the water for easy retrieval. It uses inductive charging and wireless programming updates, allowing it to be completely sealed for exceptional weather protection. The U3 combines the convenience and low power requirements of an electronic paper display with fully programmable soft-touch buttons for quick access to commonly used functions. The display is easy to read in bright light—even outdoors—and can be customized to each project via the award-winning RTI Integration Designer programming software.
