Code 1
(cont.)
Coding in the delivered condition
Solar circuit pump minimum speed
74:30
Minimum permissible speed of so-
lar circuit pump, 30 % of maximum
possible pump speed
Nominal flow rate collector circuit
75:0.0
No flow rate
DHW
Coding
Coding in the delivered condition
DHW differential
0C:0
The differential temperature of
DHW heating (difference between
system temperature and DHW
temperature) is determined auto-
matically.
DHW return temperature
0D:10
Flow control active. Set return tem-
perature corresponds to DHW tem-
perature plus 10 °C
Additional heat generator
Is available if code "Additional boiler: Yes", hard-
ware group, is set.
Coding
Coding in the delivered condition
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.
Possible change
74:10
Setting range in %
to
74:100
75:0.1
Nominal flow rate of collector circuit
to
in l/min. Adjustable from 0.1 l/min to
75:50.0
50 l/min.
Possible change
0C:0
Fixed setting of differential tempera-
to
ture from 1 °C to 20 °C
0C:20
0D:0
Flow control deactivated. Valve is al-
ways fully opened.
0D:1
Flow control active. Set return tem-
to
perature corresponds to DHW tem-
0D:30
perature plus value set in °C.
Possible change
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.
