Displaying / Modifying Control Parameters - Wolf CGB-11 Installation Instructions Manual

Modifications must only the carried out by a
NB
recognised heating contractor or by Wolf cu-
stomer service.
Incorrect operation can lead to system faults.
NB
Please note when using parameter GB 05 or
A09 (frost protection/outside temperature), that
frost protection is not safeguarded if you set
temperatures lower than 0 °C. This can lead to
heating system damage.
The control parameter can be modified or displayed via controller with eBUS capability. For procedures, check the operating in-
structions of the relevant accessories.
Settings of column 1 are suitable for control accessories ART and AWT.
Settings of column 2 are suitable for Wolf control systems with BM (programming unit)
