When trying to set up a space to have economizer mode using the schedule, i
can't seem to make it work.
When i enter the value 0.001 as requested by the help files, to enable
economizer mode and let the unit go to 0% during the unoccupied periods, it
doesn't work.
When i enter -999 as requested by the help files to allow my stated OA ratio
to rule (33% in this case) it doesn't allow it to go to 100% OA and
therefore i get unmet hours.
If i set the value to 1 at all times, then i get 100% OA during the summer,
which is not advised.
Any help is appreciated,

You might have already done it, did you set OA control to something other
than fixed - also economizer is just at the system level, not space level.
Space level inputs will override system level inputs here. May want to check
those.
For OA, that is.
I have entered no space inputs for OA, everything has been entered at System
level. I have a dual temperature economizer set up.

When i set the high temperature limit to 65 deg, this caused the economizer
to operate as it is supposed to.
Hope this helps for future economizer issues.
