<p class="MsoNormal">Hello out there!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am modeling some PTHPs in a hotel guest room for my baseline model. The design has ventilation airflow of 40 cfm and bath exhaust of 35cfm. My input screen for a typical zone is show in Fig 1 below. I get a warning which reads:
<i> ZONE EL3 South Perim Zn (G.S2 in SYSTEM EL3 Sys1 (PTAC) (G.S2) has unused EXHAUST-CFM specified. This has been converted to outside air.
</i>(See Fig 2). Looking at the hourly reports the exhaust flow looks good (`~35cfm) , but it doesn’t show a supply airflow (Fig 3). However, the summary report shows design OA = 40 cfm. (Fig 4)<o:p></o:p></p>
