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.
