Fault messages

If a fault is indicated by the signal ring of the control unit fl ashing red, a fault code is displayed 

via the Wolf control accessory with eBUS capability that allows cause and effect to be allocated 

using the following table.

This list of fault messages is designed to allow your heating contractor to trace the fault more 

easily.

No. Fault
