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 dierence is the

energy savings.

This data is displayed but does not aect 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.
