Hello,

I am modeling a project that has two different sizes of PTACs (PTAC-1 & PTAC-2). In the system tab I created two systems and assigned the different rooms to the corresponding PTAC unit. My question is regarding modeling the plant. Ignoring the heating plant for a second, am I correct in creating a two cooling plants one PTAC-1 with 0.6 tons and another PTAC-2 with 0.75 tons? Then assigning the corresponding systems to the plants? Or do I need to modeling PTAT-1 with 0.6 tons by 100 units = 60 tons?

Thank you very much!
