Modifications must only the carried out by a recognised heating contractor or by the Wolf customer service.
Incorrect operation can lead to system faults.
To prevent damage to the entire heating system, cancel night setback when connecting a BM-2 module and
outside temperatures fall below -12 °C. If this rule is not observed, ice may build up on the flue outlet which
may cause personal injury or material losses.
Please note
The control parameters can only be modified or displayed via the integral control unit.
