I'm looking for help with a two-pipe chilled water hot water system that
does seasonal switchover.  This is a large high school campus and
initially I used design development wizard to create a four-pipe system
(since two-pipe doesn't seem to be a choice).

The four-pipe system works fine but after using the detailed data edit
to convert it to a two-pipe system it doesn't work. If anyone has
experience with a two pipe system and can help I would appreciate it.
The specified chilled water flow is 2640 gpm.  It also is not showing
the internal loads for most of the spaces.

Attached is the .pd2 and .inp file.
