Operating the pump
Twin-head pumps can be set and operated in the
same way as single-head pumps. The duty pump
uses its setpoint setting, whether it is made on the
control panel, with the R100 or via bus.
Both pumps should be set to the same
setpoint and control mode.
Note
Different settings will result in different
operation when changing between the
two pumps.

7.10 Connection to LON network

The pump can be connected to a LON network via a
GENI module and an external Grundfos G10 LON
interface. Product number: 605726.
