‘Wells TheONE’ water purifier has the stylish and handy circular control panel with a touch wheel and LCD display for compact body. Six-step water temperature and 4-type flow rate are controlled intuitively by two touch wheels on both sides of the panel. It also offers a guide for an easy choice of desired functions using the thin projecting line and icon. Temperature and flow rate are shown on the LCD display on the control panel. Users may choose between black and pastel skin colors for the display. The black skin focuses on the center with the immersive background image and limited color, while the pastel skin cleverly portrays water temperature in color.
