Re: [EnergyPlus_Support] heat recovery

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

The mixing box and it's controller are needed to set the flow rate 
for the outside air stream.  If you set the minimum outside air flow  
to equal the supply air flow then you will get 100% outside, and 
therefore no mixing as desired.
