24. 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 BM2 programming module, the factory setting for the HG parameters
can be reinstated in the Contractor menu.
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.
Caution
Caution
The control parameters can only be modified or displayed using the AM display module or BM2 programming
module on the boiler. For procedures, check the operating instructions of the relevant accessories.
