Coding in the delivered condition Possible change
Min. flow temperature heating circuit
C5:20 Electronic minimum flow tempera-
ture limit 20 °C (only for weather-
compensated control units)
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 74 °C (only for weather-
compensated control units)
C6:10
to
C6:127
Maximum limit adjustable from 10 to
127 °C (limited by boiler-specific pa-
rameters)
Heating program changeover
D5:0 The external operating program
changeover switches the operating
program to "Constant operation
with reduced room temperature" or
"Standby mode" (only for weather-
compensated control units)
D5:1 The external operating program
changeover switches to "Continuous
operation with standard room tem-
perature" (subject to coding ad-
dresses 3A, 3B and 3C)
Ext. operating program changeover to heating circuit
D8:0 No operating program changeover
via EA1 extension
D8:1 Operating program changeover via
input DE1 at EA1 extension
D8:2 Operating program changeover via
input DE2 at EA1 extension
D8:3 Operating program changeover via
input DE3 at EA1 extension
Max. pump speed in standard mode
E6:... Maximum speed of the variable
speed heating circuit pump in % of
the max. speed in standard mode.
Value is specified by boiler-specific
parameters (only for weather-com-
pensated control units).
E6:0
to
E6:100
Maximum speed adjustable from 0
to 100 %
Min. pump speed
E7:30 Minimum speed of the variable
speed heating circuit pump: 30 %
of the max. speed (only for weath-
er-compensated control units)
E7:0
to
E7:100
Minimum speed adjustable from 0 to
100 % of maximum speed
Screed drying
F1:0 Screed drying disabled (only for
weather-compensated control
units).
F1:1
to
F1:6
Screed drying can be set in accord-
ance with 6 adjustable temperature/
time profiles.
F1:15 Constant flow temperature 20 °C
