4.5 Setting parameters
Operating the programming mode
B To enter the programming mode, simultaneously hold
down
d (“Chimney Sweep”) and e (“status display”)
for five seconds.
B To change to the next parameter, press
e again.
B To reduce the parameter value ( – ), press “Reset”.
B To increase the parameter value (+), press
d again.
Programming mode is terminated if no key is pressed for
five minutes.
Fig. 15 Setting parameters
4.5.1 Limiting the heating load
Parameter L-- is used to reduce the burner output for
heating mode (only with two-stage or modulating
burners). This extends the burner runtime and reduces the
number of burner starts. Subject to the heating system
design, this will save energy.
This parameter can be recognised by the letter “L”.
The L-- setting means that the rated boiler output is not
restricted.
xx The lowest possible setting is burner-dependent.
4.5.2 Pump run-on time
With parameter F5, the boiler pump run-on time can be
set in minutes.
This parameter can be recognised by the letter “F”.
The setting F1d means the boiler pump runs constantly.
4.5.3 DHW
Parameter C0 is used to determine whether DHW is to be
heated by the boiler.
This parameter can be recognised by the letter “C”.
Setting 0 also disables frost protection for the DHW lines.
4.5.4 Burner fan speed
Parameters 1. and 2. enable a correction of the
combustion air supply. With this setting, the burner can
be adjusted during commissioning.
Input range Standard setting

100 % (L--)
If you reduce the burner output, the heating
system does not heat up as quickly. If you
reduce the burner output too much, the
temperature in the building may be too low
for comfort.
B Ensure that the selected value is higher
than the maximum burner output required
to heat the building.

and on burners that allow this correction to
be carried out electronically.
