[EnergyPlus_Support] Re: How can I simulate a stuck open economizer?



Watch out! Read very carefully the object section on the Controler for ODA in the ioRef. Some fields override or take the maximum of others. Be careful of default setting also in fields you are not planning to use. This can be a tricky object and it includes the control of the economizer action. 

I stand corrected, but as I understand it "econimizer" means a control methodology of the Mixing Damper in the "Umluftkammer" of an AHU (in e+ this is the mixing box). If the damper is jammed open, you have only circulating air. If the damper is jammed closed you have a dedicated outdoor air system without mixing.

I've not seen an AHU with a 3rd duct to outside serving as an extra intake.
