Coding in the delivered condition
Possible change
Min. flow temperature heating circuit
C5:20
Electronic minimum flow tempera-
ture limit 20 °C (only for operation
with standard room temperature)
C5:1
to
C5:127
Minimum limit adjustable from 1 to
127 °C (limited by boiler-specific pa-
rameters)
Max. flow temperature heating circuit
C6:74
Electronic maximum flow tempera-
ture limit set to 74 °C
C6:10
to
C6:127
Maximum limit adjustable from 10 to
127 °C (limited by boiler-specific pa-
rameters)
Heating program changeover
d5:0
With external heating program
changeover (observe setting for
coding addresses "3A", "3b" and
"3C" in the
"General"
group).
Heating program switches to "Con-
stant central heating with reduced
room temperature" or "Standby
mode" (subject to the value selec-
ted for the set reduced room tem-
perature).
d5:1
Heating program switches to "Con-
stant operation with standard room
temperature".
Ext. heating program changeover to heating circuit
d8:0
With EA1 extension:
No operating program changeover.
d8:1
Operating program changeover via
input DE1.
d8:2
Operating program changeover via
input DE2.
d8:3
Operating program changeover via
input DE3.
Max. pump speed in standard mode
E6:...
Only for heating systems without a
heating circuit with mixer:
Maximum speed of the internal
speed-controlled heating circuit
pump in % of the max. speed in
standard mode. Value is specified
by boiler-specific parameters (only
for weather-compensated control
units).
E6:0
to
E6:100
Maximum speed adjustable from 0
to 100 %
Min. pump speed
E7:30
Only for heating systems without a
heating circuit with mixer:
Minimum speed of the internal
speed-controlled heating circuit
pump:
30 % of the max. speed (only for
weather-compensated control
units)
E7:0
to
E7:100
Minimum speed adjustable from 0 to
100 % of the maximum speed
