where n
HIGH
is Motor Speed High Limit and n
STAGE100%
is the value
of Staging Threshold.
25-46 Destaging Speed [RPM]
Option: Function:
0 N/A Readout of the below calculated value for Destaging Speed. When removing a fixed speed com-
pressor, in order to prevent an undershoot of pressure, the variable speed compressor ramps up to
a higher speed. When the variable speed compressor reaches the “Destaging Speed” the fixed speed
compressor is destaged. Destaging Speed is calculated based on
Destaging Threshold , par. 25-43,
and
Motor Speed High Limit , par. 4-13.
