inder heating stays in
control mode at signal
"External blocking"
5F:0 Circulation pump for cyl-
inder heating stays in
control mode at signal

60:20 During DHW heating, the
boiler water temperature
is max. 20 K higher than
the set DHW tempera-
ture
62:2 Circulation pump with
2 min run-on time after
cylinder heating
63:0 Without auxiliary function
for DHW heating (only for
constant temperature
control units)
65:0 Never adjust!
67:40 For solar DHW heating:
Set DHW temperature
40 °C. Reheating is sup-
pressed above the selec-
ted set temperature
(DHW heating blocked by
the boiler).
