The multipump function enables the control of two to four single-head pumps
connected in parallel and twin-head pumps without the use of external
controllers. The pumps in a multipump system communicate with each other
via the wireless GENIair connection or the wired GENI connection.

19. Bus signal
The pump supports serial communication via an
RS-485 input. The communication is carried out
according to Grundfos GENIbus protocol and enables
connection to other pumps as well as a building
management system or another external control
system.
Via a bus signal, you can remote-set pump operating
parameters, such as setpoint and operating mode. At
the same time, the pump can, via the bus, provide
status information about important parameters, such
as actual value of control parameter, input power and
fault indications.
Contact Grundfos for further information.
If you use a bus signal, the number of
settings available via Grundfos GO are
reduced.
