Hi All:

I'm modeling a plant that is manually changed over from heating to
cooling, and I'm wondering the best way to model this. Is this done in
the systems annual heat and cool schedules, or can this be done with
annual schedules for the Water-Side equipment? Do I need to create a
new ON/OFF schedule, and if so how do I link it to the boilers and
chillers?

I'm in detailed edit mode, and have a feeling this is a simple task, but
just can't figure out how.

thanks,
