[EnergyPlus_Support] Full Fresh Air system with heat recovery and NO heating or cooling coils in loop



Hello all,

Has anyone modelled a Single Duct VAV system that takes full fresh 
air which moderates all zonal loads through a heat recovery unit 
only?

I received this fatal error?

   **  Fatal  ** ManageControllers: Invalid controller=AHU1 OA 
CONTROLLER. The only valid controller type for an Air Primary Loop 
is CONTROLLER:SIMPLE.
   ************* Fatal error -- final processing.  More error 
messages may appear.

I don't have a CONTROLLER:SIMPLE because my AHU does NOT contain a 
cooling coil or a heating coil. The facility's system designers 
expect the rotary wheel will moderate all sensible and latent loads 
in their entirety. 

Does anyone have any ideas how I could emulate such a system?

Does anyone have an example file of a FULL fresh air system with NO 
recirc air?

Kind regards

-Elmer
