Hi
Just a quick question - most PCBs contain potentiometer's - eg CH or DHW pots - what exactly do these do? I know they can be adjusted but was just trying to work out what they are for?
When you turn the CH dial for eg on a combi - does this in effect increase/decrease the potentiometer to allow more of less power to the CH thermistor? Does anyone know?
