Re: [EnergyPlus_Support] cross mixing

["Michael J. Witte" <mjwitte@xxxxxxxx>]

For MIXING and CROSS MIXING, if the delta temperature is set to zero, then air 
will flow between the zones anytime the schedule value is non-zero regardless 
of the temperatures in the two zones.  There is not a good example of your 
application.  ADS_SIMPLE_SmallOffice.idf
uses MIXING and CROSS MIXING, but it also uses the ADS airflow objects which 
makes it a more complex example.
