Connection, digital Wolf control accessories
(e.g. BM-2, MM, KM, SM1, SM2)
Only connect control units from the Wolf accessory range.
Each accessory is supplied with its own connection diagram.
Use a two-core cable (cross-section > 0.5 mm²) as the
connecting cable between the control unit accessory and the
BWL-1S (1 is + and 2 is -).
When installing the appliance in places
where there is a risk of high electromagnetic
interference, it is advisable to fit shielded
sensor and eBUS cables. The cable shield
should be connected at one end to the PE
potential in the control unit.
