.
467
Minimum Pump Power
(Min. pump power)
Value:
0 – 500.000 W
0
Function:
The associated power consumption at the frequency
entered in parameter 465
Minimum pump frequency
.
Description of choice:
Enter the no/low flow power reading at minimum pump
frequency entered in parameter 465.
Depending on pump size or curve select W or kW in
par. 009 index [32] and [8] for fine tuning.
468
Maximum Pump Power
(Max. pump power)
Value:
0 – 500.000 W
0
Function:
The associated power consumption at the frequency
entered in parameter 466
Minimum pump frequency
.
Description of choice:
Enter the no/low flow power reading at maximum
pump frequency entered in parameter 466.
Depending on pump size or curve select W or kW in
par. 009 index [32] and [8] for fine tuning.
469
No Flow Power Compensation
(NF power comp)
Value:
0.01 - 2
1.2
Function:
This function is used for an off-set of the no/low flow
power curve, which can be used as a safety factor or
for fine tuning of the system.
Description of choice:
Description The factor is multiplied to the power val-
ues. E.g. 1.2 will increase the power value with 1.2
over the whole frequency range.
