questions about HVAC modelling

hi again guys!

I am trying to model the HVAC system of the building that i study for my thesis and i am having some difficulties regarding which fields i should fill and which not! i have filled the fields up to group-airflow and i dont know what to do after that. I read in the big ladder software site that Sizing:Zone, Sizing:System, and Sizing:Plant will be generated by tha hvac system so, i guess i dont have to fill aynthing in these fields, right?? Also, do i have to create nodes and branches?? or i just fill the fields that are required for my hvac system?? The hvac system that exists in the buidling is a 2 pipe fancoil so, i either choose the 4 pipe option or the ideal loads one.
I am tottaly lost with this ,as i am a new user, so your help is needed!!!

hi again guys!

I am trying to model the HVAC system of the building that i study I'm studying for my thesis and i am having some difficulties regarding which fields i I should fill and which not! i not. I have filled the fields up to group-airflow group-airflow and i dont I don't know what to do after that. that.

I read in the big ladder software BigLadderSoftware site that Sizing:Zone, Sizing:System, Sizing:Zone, Sizing:System, and Sizing:Plant Sizing:Plant will be generated by tha hvac the HVAC system so, i I guess i dont I don't have to fill aynthing anything in these fields, right?? fields?

Also, do i I have to create nodes and branches?? or i branches? Or do I just fill the fields that are required for my hvac system?? HVAC system?

The hvac HVAC system that exists in the buidling building is a 2 pipe fancoil fan-coil so, i so either choose the 4 pipe option or the ideal loads one.
