Hi,

You can size systems based on ACH when you describe your system. Go to the
"Zone Components" tab then down to "Terminal Units". If each zone requires
a different ACH, uncheck the box that says "All zones are the same". Beside
Minimum Airflow you'll see a dropdown menu, the default it "cfm/person",
change that to "ACH" and you can enter your required ACH for that zone. You
can then use the arrows move onto each zone and adjust as required.
