Default how hot do you run you CH boiler
brought next idea :
If the Vaillant has 2 separate call for heat signals for DHW & CH it would be
simple enough to split the temp, at least if the boiler has 2 separate temp
settings for the 2 circuits, and the Vaillant 400 series I'm familiar with
does. Where is the problem happening?

The boiler only has a single call for heat and a single boiler output
temperature setting. The 418 I have, has a digital display and a +/-
button for temperature setting.
