The zone sizing and OA mixer are now in the same object. This is the reason why I have suggested to looking at the basic report variables to confirm what the system is actualy doing and compare with the know physic rules. It is still possible to make it behave like the old simple PurchasedIar system with the default settings.. Dr. Li
