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