58:0 Without auxiliary function for DHW
heating
59:0 Cylinder heating:
Start point -2.5 K
Stop point +2.5 K
5B:0 DHW cylinder directly connected to
boiler.
5E:0 Circulation pump for cylinder heat-

ternal demand" signal.
60:20 During DHW heating, the set boiler
water temperature is max. 20 K
higher than the set DHW tempera-
ture.
62:2 Circulation pump for cylinder heat-
ing with 2 min run-on time after cyl-
