Smart comfort and energy management with the UDG4

Experience warmth that adapts to your space. The OJ Microline UDG4 combines a responsive 3.5-inch color touchscreen with the reliability of a Class A GFCI, designed for electric radiant floor systems. With dual voltage support (120V and 240V) and dual sensing, it can respond to both air and floor conditions, helping you maintain comfort without guesswork.

Built for everyday use, this thermostat features a guided Install Wizard, a seven-day programmable schedule, and an adaptive self-learning function that adjusts runtime to align with your set temperatures. These tools offer flexibility and potential efficiency, without promising specific outcomes.
