I had a reply from one end-user that said all of his people took an certified energy manager course and they know what to do to save energy now.

There is more to a refrigeration system than going to a class for a few days and understanding what to do. This makes as much sense as tuning PLC's!

There are so many people (energy managers) running around trying to reduce head pressure 10 psi and think they have a done a good days work.
