During DHW heating, the boiler
water temperature is max. 20 K
higher than the set DHW tempera-
ture.
61:0
Circulation pump for cylinder heat-
ing starts subject to boiler water
temperature.
62:10

For solar DHW heating:
Set DHW temperature 40 °C.
Above the selected set tempera-
ture reheating is suppressed
(DHW heating by the boiler is
blocked).
