23. HG control parameters
Modifications must only be carried out by a recognised heating contractor or by Wolf customer service. Incorrect
operation can lead to system faults.
On the AM display module or the BM-2 programming unit, the factory setting for the HG parameters can be
reinstated in the contractor menu.
To prevent damage to the heating system, cancel night setback if outside temperatures fall below -12 °C. If this
requirement is not observed, ice may form on the flue outlet which may cause injury or material losses.
Please
note
Please
note
The control parameters can only be modified or displayed using the AM display module or BM-2 programming unit on the heat
generator. For procedures, check the operating instructions of the relevant accessories.
