What are the C & E for on the Blue dial of an Arriston boiler

Jeff Knott, February 2007

c=comfort
e= economy
It means when on c the boiler will fire itself up every now and then to keep itself hot which will enable it to deliver hot water a little bit quicker than if the the boiler was stone cold.
Hope this makes sense, if not post another question
