The Changhong CH-A90 is a wall-mounted water dispenser that can be installed in kitchens, living rooms or offices. It provides cold or warm water at any time since it is connected to the water supply of the building. The touch screen panel has the shape of a large toggle switch and can be used to switch the water dispenser on and off. This facilitates filling different kinds of containers, especially bottles. Different LEDs at the edge of the nozzle indicate different water temperatures: blue for cold water, orange for warm water and red for hot water.
