Also referred to as control knobs and temperature knobs, they usually sit on a spindle located on the front of the boiler the spindle when turned, turns a potentiometer that’s located on the printed circuit board and if the knob is turned too hard the spindle is designed to break hence protecting the printed circuit board from damage and an expensive repair, the knob allows you to manually control aspects of the functionality of the boiler. Some boilers allow you to change temperature and some even enable you to change the current function. This means you can have the boiler generate hot water without the central heating being on or central heating on without hot water.
