Gas pedal and parking brake of the heater: Explanation correct?

I will continue to inform myself today :p

Gladly report new findings :)

There should be a kind of layman's manual that describes different options and their effects. Or FAQs...

Actually, it's quite simple as long as the heating engineer hasn't messed up the hydraulics.

-Flow temperature as low as possible
-Running time as long as possible
-Adjust flow rate only with the HKV
-Adjust temperature via the heating curve

After that, ideally, you never need to touch the heating system again

that is again too easy...

But still helpful at first to know the most important tasks. By runtime, do you mean not cooling down the system overnight with a lower temperature?
