The DOAS system uses a CoilSystem:Cooling:xxx object that provides control for DOAS supply air. The AirLoopHVAC object needs a zone temperature for control.
CoilSystem:Cooling:xxx will not accept Coil:Cooling:WaterToAirHeatPump:EquationFit as a valid coil. Guess I have to look elsewhere�

OK. I know what that is :)
Are you trying to insert
AirLoopHVAC:UnitaryHeatPump:WaterToAir?
or
ZoneHVAC:etc........
The ZoneHVAC version won't work in an air loop because it's a zone object. the AirLoopHVAC object should work, however.

Ned,
What is a WAHP? I'm not familiar with that abbreviation.

I’ve been building a complex WAHP system for a proposed building. The design includes a WAHP DOAS ventilation air. I used a template to build the base system, but the resulting DOAS system can only use water or DX coils. I tried inserting a WAHP coil, but it is an invalid air loop component. I can probably piece together an EMS solution, but I thought I would ask if anyone has implemented a more direct solution to a common issue.
