<p class=MsoNormal>I want to setup a system where the OA volume is set to 0 for
setback heating/cooling. Under the help for “Minimum Air
Schedule”, it says that you can set up a schedule where the values for
min OA range from 0 to 1.0, but a value of -999 defaults that particular hour
to whatever the zone calcs require.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This is perfect, except the only type of schedule that you
can input into MIN-AIR-SCH is type FRACTION, and the FRACTION schedule
won’t accept -999. Only from 0 to 1.0.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What am I doing wrong? Thanks in advance,<o:p></o:p></p>
