Parameter
(cont.)
7 "Maximum heating output"
Setting
8 "Maximum flow temperature limit, heating circuit 1"
Setting
74 °C
9 "Operating mode, heating circuit 1"
Setting
10 "Room influence factor, heating circuit 1"
Setting
8
11 "Maximum flow temperature limit, heating circuit 2"
Setting
74 °C
12 "Operating mode of heating circuit 2"
Setting
Weather-compensated without room tem-
perature hook-up
Weather-compensated with room tempera-
ture hook-up
Explanations
A limit can be set on the maximum heating output for
heating mode.
100
Heating output in the delivered condition 100 %
0 to 100
Adjustable from 0 to 100 %
Explanations
Maximum flow temperature limit for the heating circuit
74
Maximum limit in the delivered condition 74 °C
10 to 100
Setting range limited by heat generator-specific pa-
rameters
Explanations
Only adjust if there is just a single heating circuit in the
system.
4
Weather-compensated without room temperature in-
fluence
7
Weather-compensated with room temperature influ-
ence; see also parameter 10.
Explanations
The higher the value, the greater the influence of the
room temperature on the set flow temperature of the
heating circuit (heating curve). Operation with room
temperature hook-up must be set for the heating cir-
cuit. Only change the value for systems with one heat-
ing circuit. For a sample calculation, see chapter
"Heating curve" under "Function description"
8
Maximum limit in the delivered condition
0 to 64
Setting range
Explanations
Maximum flow temperature limit for the heating circuit
74
Maximum limit in the delivered condition 74 °C
10 to 100
Setting range limited by heat generator-specific pa-
rameters
Explanations
Heating mode:
4
Weather-compensated without room temperature in-
fluence
7
Weather-compensated with room temperature influ-
ence
See parameter 13.
