[EnergyPlus_Support] Re: CO2 buildup control

["Elmer Morrissey" <elmofuddly@xxxxxxxxx>]

Hi,

Yeah, I have everything laid out as you have specified below. The 
file itself is uploaded in the Files section of the website named 
AHU3_BenchmarkMetricMV.idf. The additions I made when trying to add 
this object is:

* Mechanical:Ventilation object 
* Reference to the Mechanical:Ventilation object in the Outside Air 
Controller
* A list of two zones: "zFlr3MediaRoom & zFlr3CloseControl" 
referenced by the Mechanical:Ventilation object

Have I missed anything, I have looked through the 
HeatPumpSimpleDCV.idf example, but I cannot spot how my file 
differs. 

Kind regards

-Elmer
