[Equest-users] economizer mode for a liebert unit

[Edward.A.Decker at jci.com]

Hello All,

A colleague of mine is trying to simulate a data center. The center is 
currently served by Liebert units (so 0 OA). He would like to try and add 
some type of economizer cooling by bringing in OA when the outside 
temperature is below 55 deg F. When the outside temp is above 55 deg F he 
would like to shut off the OA. Any suggestions on how to model this? Is 
there a way to maybe schedule economizer cooling and/or outside air ratios 
based on outside air temperatures? Any help with this would be greatly 
appreciated.

Regards,

Eddie
