During the unoccupied mode, water-cooled units will
periodically circulate water through the condensers
and waterside economizer if the user has enabled the
purge function at the HI. The water purge function
circulates water to introduce fresh water-treatment
chemicals and help prevent water stagnation. The
number of hours between each periodic purge, or
purge duration, is user-defined at the HI between 1-999
hours. If the periodic purge timer expires while the unit
is in occupied mode, it will wait for the next available
unoccupied time before initiating water purge.
Contrary, if a request for cooling occurs during a purge
sequence, purge will terminate and cooling will
commence.
