Iâ??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. Â
