25-46 Destaging Speed [RPM]
Range:
Function:
0 RPM*
[0 - 0 RPM]
Readout of the below calculated value for Destaging Speed. When removing a fixed speed pump,
in order to prevent an undershoot of pressure, the variable speed pump ramps up to a higher speed.
When the variable speed pump reaches the “Destaging Speed” the fixed speed pump is destaged.
Destaging Speed is calculated based on par.25-43
Destaging Speed is calculated with the following formula:
DESTAGE
=
HIGH
DESTAGE
%

where n
HIGH
is Motor Speed High Limit and n
DESTAGE100%
is the
value of Destaging Threshold.
