Grundfos Direct Sensors™
In this menu the Grundfos Direct Sensors™ can be registered.
For Grundfos Direct Sensor™ positioning, see the system layout drawing on p.
63!
If Grundfos Direct Sensors™ are connected and registered, ow rate monitoring
OFLOW can be carried out during solar loading. For that purpose, the VFS sensor
must be installed in the solar ow. If no ow rate has been detected for 30 s, the
error message EFLOW is displayed in the status menu (see ow rate monitoring
option).
Note:
To deactivate a Grundfos Direct Sensor
TM
, the functions using this sensor
have to be deactivated rst.
Flow rate monitoring
The Flow rate monitoring function can be used to detect malfunctions that impede
the ow rate. This will prevent system damage, e. g. through a dry run of the pump.
Note:
To deactivate the VFS or RPS sensor, the functions using this sensor have
to be deactivated rst.

Pressure monitoring
Note:
The pressure monitoring function will only be available when an RPD
type Grundfos Direct Sensor™ is connected.
The Pressure monitoring function can be used for detecting overpressure or low
pressure conditions inside the system. This will prevent system damage.
Overpressure
If the system pressure exceeds the adjustable switch-on value, an error message
will appear.
When the pressure reaches or falls below the adjustable switch-off value, the mes-
sage disappears.
Note:
For the Overpressure monitoring function, the switch-on value has to
be adjusted at least 0.1 bar higher than the switch-off value. The adjust-
ment ranges will automatically adapt to that.
