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.
Note: Both pumps should be set to the same set-
point and control mode. Different settings will result
in different operation when changing between the
two pumps.
6.10 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: 00605726.
