[Equest-users] Setting after-hours OA volume to zero usingMIN-AIR-SCH

[Molly Curtz]

Hi James, 

Try  TYPE = FRAC/DESIGN

That should work with the -999 values.

 

Best,

usingMIN-AIR-SCH

 

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.

 

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.

 

What am I doing wrong?  Thanks in advance,
