"Pumps and Aux" under Fuel Use?

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!

Isn't that where a pilot light resides?

Pilot light? That?s reasonable but would be constant, right? This appears as fluctuating.

Thanks, Richard, for offering crankcase heat, but the MUAU is heat only. I?ve always had crankcase heat available for the PSZs but this use never showed up until I added the MUAU and EF system in the dummy zone.

I would go under auxiliary heating and set the pilot to zero and find out if this is what is causing it to show up in the auxiliary section.
