The Robinson Willey control knob is located on one of the spindles on the front of the appliance and allows the user to control certain aspects of the appliance's operation manually. Some boilers allow the user to change the temperature, while others allow the user to change the current function. This means that the user can have the boiler provide hot water without turning on the central heating and vice versa.
