The Vokera selector switch knob is located on one of the spindles on the front of the control panel and allows the user to manually control certain aspects of the appliance's operation. 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 generate hot water without turning on the central heating and vice versa.
