I was excited about this once but the first pass showed it wouldn’t payoff for my project. If your situation shows promise, you need a detailed model, and if an eQUEST waterside economizer will not give you the series functionality, then I wonder if you could model the modes as separate air cooled chillers in eQUEST with custom curves for each and staging based on outdoor air or seasonal dates. Good luck.<u></u><u></u></span></p>
