Vaillant Control Knobs
The control knob sits on one of the spindles located on the front of the control panel and allows the user to manually control certain aspects of the appliances operation. Some boilers allow you to change temperature and some even enable you to change the current function. This means the user can have the boiler produce hot water without the central heating being on and vice versa.
