Codes
Code 1
(cont.)
Coding in the delivered condition
Set buffer temperature ignition
FD:50
If the average heating water buffer
cylinder temperature falls below
50 °C, the boiler can be started.
This code is only available if auto-
matic ignition is used.
Ignition runtime
FE:15
Max. runtime of 15 minutes for the
ignition fan. This code is only avail-
able if automatic ignition is used.
Solar (if heating circuit extension module installed)
Coding
Coding in the delivered condition
Differential DHW
6E:10
Differential temperature of 10 K
between solar and DHW heating to
start DHW heating by the solar
thermal system
Maximum temperature DHW
6F:70
Max. DHW temperature limit when
heated by the solar thermal sys-
tem. DHW is heated by the solar
thermal system up to this tempera-
ture.
Differential buffer
70:20
Differential temperature of 20 K
between solar and heating water
buffer cylinder to start heating wa-
ter buffer cylinder by the solar ther-
mal system
Additional function solar
71:0
Additional function of cylinder heat-
ing by the solar thermal system
disabled.
Code only available when DHW
heating is connected to the boiler.
Additional function runtime
72:0
Circulation pump off.
Solar circuit pump maximum speed
73:100
Maximum permissible speed of so-
lar circuit pump, 100 % of maxi-
mum possible pump speed
52
Possible change
FD:20
Min. average temperature in °C
to
FD:70
FE:0
Automatic ignition is disabled
FE:1
Setting range in minutes.
to
FE:60
Possible change
6E:1
Setting range of differential tempera-
to
ture in K
6E:50
6F:0
Setting range in °C
to
6F:100
70:1
Setting range in °C
to
70:50
71:0
Start time of the solar additional
to
function. Solar additional function:
71:23
Signal for starting the transfer pump
of the solar thermal system. This al-
so heats the lower area of the DHW
cylinder to the required temperature.
Time adjustable from 01:00 h
("71:1") to 23:00 h ("71:23")
72:0
Runtime of solar de-stratification
to
pump in min, adjustable from 1 min
72:180
to 180 min. Only available with code
"71:1 - 23".
73:10
Setting range in %
to
73:100
