Hg Control Parameters - Wolf CGB-2 Service Instructions Manual

Modifications must only be carried out by a recognised heating contractor or by Wolf customer service.
Please
Incorrect operation can lead to system faults.
note
On the AM display module or the BM2 programming unit, the factory setting for the HG parameters can be
Please
reinstated in the Contractor menu.
note
To prevent damage to the heating system, cancel night setback when outside temperatures fall below -12 °C.
Failure to observe this requirement may result in ice forming on the flue outlet which may cause injury or
material losses.
The control parameters can only be modified or displayed using the AM display module or BM-2 programming unit on the boiler.
For procedures, check the operating instructions of the relevant accessories.
