Function:
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
and Motor Speed High Limit , par. 4-13.
