Possible change
Solar circuit pump minimum speed
74:30
Minimum permissible speed of so-
lar circuit pump, 30 % of maximum
possible pump speed
74:10
to
74:100
Setting range in %
Nominal flow rate collector circuit
75:0.0
No flow rate
75:0.1
to
75:50.0
Nominal flow rate of collector circuit
in l/min. Adjustable from 0.1 l/min to
50 l/min.
DHW
Coding
Coding in the delivered condition
Possible change
DHW differential
0C:0
The differential temperature of
DHW heating (difference between
system temperature and DHW
temperature) is determined auto-
matically.
0C:0
to
0C:20
Fixed setting of differential tempera-
ture from 1 °C to 20 °C
DHW return temperature
0D:10
Flow control active. Set return tem-
perature corresponds to DHW tem-
perature plus 10 °C
0D:0
Flow control deactivated. Valve is al-
ways fully opened.
0D:1
to
0D:30
Flow control active. Set return tem-
perature corresponds to DHW tem-
perature plus value set in °C.
Additional heat generator
Is available if code
"Additional boiler: Yes"
, hard-
ware group, is set.
Coding
Coding in the delivered condition
Possible change
Buffer charging until sensor
D0:1
The additional heat generator
charges the heating water buffer
cylinder up to the first buffer tem-
perature sensor.
Note
Only useful if the additional heat
generator has its own boiler circuit
pump.
D0:0
The heating water buffer cylinder
temperatures are ignored.
D0:2
The additional heat generator charg-
es the heating water buffer cylinder
up to the
second
buffer temperature
sensor.
D0:3
The additional heat generator charg-
es the heating water buffer cylinder
up to the
third
buffer temperature
sensor.
D0:4
The additional heat generator charg-
es the heating water buffer cylinder
up to the
fourth
buffer temperature
sensor.
D0:5
The additional heat generator charg-
es the heating water buffer cylinder
up to the
fifth
buffer temperature
sensor.
