<p class="MsoNormal"><span style="color:#1F497D">In the wizards you can assign exhaust quantities for specific zones at the zone group definitions screen (towards the end while editing a shell).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Assigning a quantity here during wizards is good for a placeholder in my experience, but I generally plan for giving all exhaust inputs and associated scheduling a second pass during detailed mode for review
and further editing, to be sure I’m capturing the correct behavior. <o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">An extra caution comes to mind: zonal exhaust bypasses any attempts at heat recovery, so one should come up with a strategy during the wizards if you’re dealing with central unit energy recovery and/or recovering
DOAS’s.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">If anyone needs a refresher in energy recovery, I advise searching for ‘Brian Fountain recovery’ in the archives. For the current version of eQuest (3.64), I think this guy and fellow list contributors have
nailed most sides of the topic down pretty well in layman’s terms. There’s also a thread from some years back I’ve personally referenced often where Brian helped me get a grip on how system level exhaust is more-or-less indirectly defined…
