OPTISAVE ENERGY ANALYSER FEATURE
The
OptiSave Energy Analyzer Feature
reveals the
advantage of a compressor motor variable speed drive.
It calculates the amount of energy that has been saved
by having a variable speed drive instead of a constant
speed drive. The savings are determined by calculating
the energy consumption of a constant speed drive and
subtracting the measured energy consumption of the
variable speed drive. The resulting difference is the
energy savings.
This data is displayed but does not affect chiller op-
eration or performance. This feature is available in
software versions C.MLM.02.05.xxx (and later) and
C.OPT.02.05.301 (and later). It is not operational until
enabled using a special procedure. A complete descrip-
tion and all required installation, enable and setup in-
formation is contained in YORK Service Information
Letter SI0068.
