HOW DOES IT WORK ?
At the core of each thermostatic product, there is a small part which is called the thermostatic element.
Inside this element, there is wax based paste. When this paste is heated, it expands and grows larger, and it pushes the metal rod of the element (the piston). This movement is the basis of operation of the applications. It will be used to adjust the inlet of hot and cold water, or hot and cold air.
The thermostatic element is in fact a smart thermometer, which is independent and very precise. It analyses its environment without you asking it to do it, in order to ensure that you have the temperature that you want.
