Can OS1.9 simulate a packaged VAV system with water-cooled units and elec heating? I think DX units in the library are air-cooled since there is no place to link them to condenser water loop. I am thinking about using AirLoopHVAC Unitary System. However, the only water-cooled and VAV options are "Unitary - CW cooling - HW heating - VAV - HW reheat". But it is HW heating not elec heating&reheat. My system is elec heating.
