Alpha Control Knobs
The control knob resides on one of the spindles located on the front of the control panel and allows you to manually control certain aspects of the boilers functionality. 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 provide hot water without the central heating being turned on and vice versa.
