I'm modeling a small office building using PSZs (residential furnaces w/ DX cooling). Runs had not shown any natural gas use under "Pumps and Auxiliary" until I added a gas fired makeup air unit and exhaust fan. These are for a kitchen hood. I set these up as a separate system in a "dummy" zone as previously discussed here.

The model runs clean with no errors (but a BUNCH of additional gas use!), and now also shows gas being used under "Pumps and Aux."

Can anyone advise how eQ assigned fuel use to this category and how it might be adjusted?

Thanks!
