It will show a bunch of information about chillers, heaters, alarms and stuff. It pretty much helps you out. 
At the R> prompt, P DR 4, or any other number will show the status of drums (some chiller part). Sometimes at 
the R> prompt, typing &g, will get you these cool history reports. Explore as you wish.
