<p>Dear All,<o:p></o:p></p>
<p>If a constant volume rooftop is controlled with a thermostat located in a zone, then we have to use either PSZ or PVVT systems to define its control zone.<o:p></o:p></p>
<p>How would one model a control where the rooftop supply air temperature setpoint is set according to the return air temperature (ie. average of zone temperatures)?<o:p></o:p></p>
<p>Thank you in advance,<o:p></o:p></p>
