Yep - Julien has the right idea!

The other input of interest for your case is that at the same input screen, you can select the exhaust source as "infiltration," which means the associated makeup airstream = outside conditions.

Zonal exhaust fan has an option to control that on a temp schedule if I recall correctly.

Open the zone, tab "outside air" then at the right you can specify a zonal exhaust fan. (All this from memory so might differ slightly)

Cheers,
Julien
