I am modeling an ASHRAE system type 6 and cannot seem to get equest to
model this system type. I have tried to user override the VAV to parallel
but that does not work. The default expression is set up to only allow
parallel piu boxes for a piu system, but the only available piu system type
is chilled water. Any suggestions to override the VAV box type or the
system type to DX from CHW would be helpful.

Thanks in advance,

Caleb
