The x-change dynamic AW E air/water heat pump is an extremely energy-efficient heat source for outdoor installation. The straight-line design fits harmoniously into a modern living space, combining aesthetics and functional elements. The ribs for the air outlet are completely integrated in the front. The green rib provides a splash of color and symbolizes a "green" heat source with regenerative energy. The x-center x40 controller adopts a straight-line design. The especially designed, self-explanatory icons on the color touch display make it very easy and intuitive to operate.
