Heat quantity measurement with fl owmeter V40
The heat quantity measurement calculation uses the diffe-
rence between fl ow and return temperature and the volume
fl ow transmitted by the fl owmeter.
Î
Adjust 2 in the channel FTYPE
Î
In the channel FIMP, adjust the impulse rate correspon-
ding to the V40 fl owmeter used.
Î
Adjust the antifreeze type and concentration of the heat
transfer fl uid in the channels MEDT and MED%.
Heat quantity measurement with VFS sensor:
The heat quantity measurement calculation uses the diffe-
rence between fl ow and return temperature and the volume
fl ow rate transmitted by the VFS sensor.
Î
Adjust 3 in the channel FTYPE
Î
Adjust the antifreeze type and concentration of the heat
transfer fl uid in the channels MEDT and MED%.
OHQM / FIMP
Impulse rate
Adjustment range
: 0.5 ... 99.0
in steps of 0.1
Factory setting:
1.0
Note:
To deactivate the VFS or the RPS sensor, the
functions using these sensors have to be deac-
tivated fi rst.
GFDS / OFLOW
Selection
: ON / OFF
Factory setting: OFF
HQM sensors
OHQM / SFHQM
Flow sensor
Adjustment range: 1, 2, 3, 5
Factory setting: 1
If the fl ow rate detection type FMAX or V40 has been
adjusted, the fl ow and the return sensor for heat quantity
measurement can be selected.
Î
In the channel SFHQM select the fl ow 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 fl ow sensor is S1, the return
sensor is S4.
OHQM / SRHQM
Return sensor
Adjustment range: 2, 3, 4, 5
Factory setting: 4
In this menu point the Grundfos sensors can be registered.
If Grundfos sensors (VFS) are connected and registered,
fl ow rate monitoring OFLOW can be carried out during
solar loading. If no fl ow rate has been detected for 30 s, the
error message EFLOW is diplayed in the status menu (see
fl ow rate monioring option).
