[EnergyPlus_Support] Constant Flow Ventilation Setback based on ODB

["elizabeth.ricker" <elizabeth.ricker@xxxxxxxxx>]

Hello,
   I am currently modeling a ventilation system with a constant 
volumetric flow rate.  I would like to be able to control this flow 
rate according to the temperature of the incoming outdoor air. This 
means that flow rate should be halved when the outdoor temperature 
drops below -10C.  Is there a simple way to do this?  Perhaps with a 
controller or a schedule of some kind?  I have looked through the 
EnergyPlus documentation, but have yet to find a "simple" solution.  
Any suggestions?  

Thanks,

Betsy
