Diagnostics View
This window lists the active and inactive (history)
diagnostics.There can be up to 60 diagnostics, both active
and historic. For example, if there were 5 active
diagnostics, the possible number of historic diagnostics
would be 55.You can also reset active diagnostics here,
(i.e., transfer active diagnostics to history and allow the
chiller to regenerate any active diagnostics).
