The new calculator (v2009v4_Minimum IAQ Performance Calculator_v03) from the Resources tab, does not count the ‘Zone Outdoor Airflow’ (column N) and it shows 0,00 no matter what system and values we put into calculator. Is this me or the calculator to make mistake? The 62MZ Calc has been substituted with the mentioned Calculator_v03 and can't be used any more, right? Or maby we can use the v02 calculator version?
