note:
To deactivate the VFS or the RPS sensor, the
functions using these sensors have to be deac-
tivated first.

If the flow rate detection type FMAX or V40 has been ad-
justed, the flow and the return sensor for energy metering
can be selected.
Î
In the channel SFHQM select the flow sensor.
Î
In the channel SRHQM select the return sensor.
For this function, free sensors at an appropriate position can
be selected. The pre-adjusted flow sensor is S1, the return
sensor is S4.

In this menu point the Grundfos sensors can be registered.
If Grundfos sensors (VFS) are connected and registered,
flow rate monitoring OFLOW can be carried out during
solar loading. If no flow rate has been detected for 30 s, the
error message eFLOW is diplayed in the status menu (see
flow rate monioring option).
