Ariston control knob sits on one of the spindles on the front of the appliance and allows you to manually control certain aspects of the operation of the appliance. Some boilers let you adjust the temperature, while others even let you modify the existing operation. This means that the user can have the boiler provide hot water without turning on the central heating, and vice versa.
Fits multiple appliances
