Wilo Net is a bus system that Wilo products (participants) can use to communicate with
each other.

twin-head pumps consisting of two participants
Bus topology:
The bus topology consists of several pumps (participants) connected in series. The par-
ticipants are connected via a shared cable.
The bus must be terminated at both ends of the cable. This is done for the two external
pumps in the pump menu. All other subscribers should
not have activated termination.
All bus subscribers must be assigned an individual address (Wilo Net ID).
This address is set in the pump menu of the respective pump.
