[EnergyPlus_Support] Re: CO2 buildup control

["donbshireyiii" <shirey@xxxxxxxxxxxx>]

Is Controller:Outside air = AHU3 OA CONTROLLER in a CONTROLLER LIST,
and is the CONTROLLER LIST name specified in the OUTSIDE AIR SYSTEM
(Name:Controller list) used by the air loop serving Zone name =
ZFLR3CLOSECONTROL?

Look carefully at the example file HeatPumpSimpleDCV.idf to see the
required relationships among these objects.

If this fails to fix your problem, upload your idf file to Files area
of EnergyPlus_Support@xxxxxxxxxxxxxxx, or send the file as an e-mail
attachment to EnergyPlus-Support@xxxxxxxx.
