<div>Hi All,<br></div><div><br></div><div>In a building with a Packaged Single Zone system, I inputted an economizer. However, in order for the economizer to activate, I had to enter some amount of outdoor ventilation air. If the design outdoor air was 0, no economizer, during any hours. Bug?</div>
