Has anyone got any thoughts on the correct setting for the temperature
dial on a condensing boiler please?

Its only marked MAX and MIN and has always been left on MAX since it
was installed a few years ago. Our HW stat is on 80C, because that is
what I want. Set the boiler output temperature too low and it will
constantly cycle on and off unable to achieve the demand.

Suggestions and your reasoning please?
