Wilo Net is a bus system which enables up to 21 Wilo products (participants) to communic-
ate with one another. The Wilo-Smart Gateway is one of these participants.
Application for:
• Remote access via Wilo-Smart Gateway
• Remote control
Bus topology:
The bus topology consists of several participants connected in series. The participants are
connected via a shared communication cable.
The bus must be terminated at both ends of the communication cable. This is done in the
settings menu for the two external participants. All other subscribers should not have ac-
tivated termination.
All bus subscribers must be assigned an individual address (Wilo Net ID).
This address is set in the system's settings menu.
To terminate:
In the "Settings" menu , select
1. "External interfaces"
