Wilo Net is a bus system which enables up to eleven Wilo products to communicate
with one another.
Application for:
▪ Double pumps consisting of two single pumps
▪ Multi-pump system
▪ Gateway
▪ Remote control
Bus topology:
The bus topology consists of multiple stations (pumps), which are switched on in se-
quence. The stations (pumps) are connected via a shared line.
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.
To terminate the pumps:
In the "Settings" menu, select
1. "External interfaces"
2. "Wilo Net setting"
