The Ariston control knob sits on one of the spindles located on the front of the control panel and allows you to manually control certain aspects of the appliance's functionality. Some boilers allow you to change the temperature and even enable you to modify the current function. This means the user can have the boiler provide central heating without the hot water being on and vice versa.
