Grundfos CUE Series Installation And Operating Instructions Manual page 19

The CUE automatically tests and sets the correct direction of
rotation without changing the cable connections.
This test is not suitable for certain pump types and will in certain
cases not be able to determine for certainty the correct direction
of rotation. In these cases, the CUE changes over to manual
setting where the direction of rotation is determined on the basis
of the installer's observations.
