Installation and operating instructions • Wilo-Stratos GIGA2.0-I, Wilo-Stratos GIGA2.0-D • Ed.02/2022-07
If pumps are delivered with a differential pressure sensor fitted, it is connected to analogue
input Al 1 at the factory.
If the differential pressure sensor is connected on-site, carry out the cable assignment as
follows:

3 Blue
Table 12: Connection; differential pressure sensor cable
NOTICE
For a twin-head pump or Y-pipe installation, connect the differential
pressure sensor to the main pump! The measuring points of the differen-
tial pressure sensor must be on the suction and discharge side of the
twin-head pump system in the common collector pipe. See "Twin-head
pump installation/Y-pipe installation" [} 149] section.
Wilo Net is a Wilo system bus used for establishing communication between Wilo products:
• two single pumps as a twin-head pump in the Y-piece or one twin-head pump in a
twin-head pump housing
• several pumps used with Multi-Flow Adaptation control mode
• Wilo-Smart Gateway and pump
For details on connection, see the detailed instructions at www.wilo.com!
NOTICE
For Stratos GIGA2.0-D, the Wilo Net cable for twin-head pump commu-
nication is factory-fitted to both electronic modules.
In order to establish the Wilo Net connection, the three H, L, GND terminals must be wired
with a communication cable from pump to pump.
Incoming and outgoing cables are clamped in a terminal.
Possible cable for Wilo Net communication:
• Y(ST)Y 2x2x0.6 telecommunications cable
