Modifications must only the carried out by
NB
a recognised heating contractor or by Wolf
customer service.
Incorrect operation can lead to system faults.
NB
Please note when adjusting parameter GB05 /
A09 (frost protection / outside temperature), that
frost protection is no longer safeguarded if you
set temperatures lower than 0 °C. This can lead
to heating system damage.
The control parameters can be modified or displayed via control accessories with eBUS capability. For procedures, check the
operating instructions of the relevant accessories.

To prevent damage to the heating system, cancel
night setback when outside temperatures fall
below - 12 °C. If this rule is not observed, ice
may build up on the flue outlet which may cause
injury or material losses.
You can find the output data for the boiler on
the type plate.
