Note!
Depending on Release QAA fan param [4337.1], the required fan speeds to be
applied differ:
If Release QAA fan param [4337.1] is set to On, the Required speed LF (9524) or
Required speed HF (9529) applies to low-fire; if set to Off, the Required speed LF
min (9525) or Required speed HF max (9530) applies to high-fire.
If a modulating pump is used, the parameterized maximum pump control ensures DHW
charging:
Degree of modulation of pump = Pump speed max (5102)
At the end of the DHW request, the pump starts to overrun. The overrun time can be
set via Pump overr time after DHW (2253).
