No ApacheHVAC results visible in Vista

The loads are now showing nicely, because system is working by using simplest prototype. Before there were no prototype and system wasn't working hence no load.

I think the whole problem was with not using prototype. Could IES explain the concept of room without air supply? Why can it be used as room with radiator?

a room can be supplied air in means other than mechanical systems, such as infiltration, natural ventilation, and transfer air.

In my prototype system, room with air supply has 0 airflow and infiltration and natural ventilation such as openable windows controlled by macroflo etc are modelled regardless of mechanical means.

If there is no prototype system with room without airflow, the concept of such rum is not clear to me as system created from scratch rather than pulled from library does not work. Placed radiators in the room have no impact on system operation, no load is applied to system whatsoever.
