History data printout
History printouts, when selected, provide stored data
relating to all specific system and chiller operating
conditions at the time of the fault, regardless of wheth-
er a lockout occurred. History information is stored in
battery-backed memory on the Chiller Control Board
and is not affected by power failures or resetting of
faults. Whenever a fault of any type occurs, all system
operating data is stored in battery-backed memory at
the instant of the fault. The history printout is similar
to the operating data printout except for the change in
the header information shown as follows:
