Bus topology:
The bus topology consists of multiple participants (pumps and Wilo-Smart Gateway), which are switched on
in sequence. The participants are connected to each other via a common cable.
The three Wilo Net terminals (H, L, GND) must be wired with a communication cable from pump to pump. In-
coming and outgoing cables are clamped in a terminal.
The bus must be terminated at both ends of the line. 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
1. "External interfaces"
2. "Wilo Net setting"
3. "Wilo Net termination".
Possible selection:
Wilo Net termination
Switched on
Switched off
After termination is done, an individual Wilo Net address is assigned to the pumps:
In the "Settings" menu
1. "External interfaces"
2. "Wilo Net setting"
3. "Wilo Net address" and assign each pump its own address (1 ... 21).
Twin-head pump example:
• Pump head left (l)
–
Wilo Net termination: ON
–
Wilo Net address: 1
• Pump head right (II)
–
Wilo Net termination: ON
–
Wilo Net address: 2
Example with Multi-Flow Adaptation featuring four pumps:
• Primary pump
–
Wilo Net termination: ON
–
Wilo Net address: 1
• Pump secondary 1:
–
Wilo Net termination: OFF
–
Wilo Net address: 2
• Pump secondary 2:
