[Equest-users] Modeling air-side economizer

Does equest require a certain HVAC "System Type" before you can add specific air-side economizer inputs?

I'm currently showing "Unit Ventilator" system type in proposed.
Equest won't allow me to add air-side economizer cycle data (dry bulb shutoff, etc...)

Also, would it be reasonable to keep the current systems as-is in equest...
Then add a "sum" system separately to allow ALL zones to receive air-side economizer cooling?
(with sum system on economizer schedule only)

I should also mention that what I'm modeling are the building's pre-existing air handlers with VFD's and no coil attachment.
Our renovation project involved keeping the old AHU's but with on-demand cooling controls.
