Water Cooled Chiller CheckForRunawayPlantTemps Fatal Error

Hello All,

I am trying to model an air-cooled chiller plant vs. a water cooled chiller plant in Open Studio to present two different options for a client. The air-cooled chiller plant worked flawlessly. The water cooled plant keeps generating a "CheckForRunawayPlantTemps" fatal error. I have checked the following:

1) Setpoint manager for condenser water plant: set to 85 degrees (F) year round. 2) Changed constant speed condenser pump to variable speed pump. No change. 3) Made sure to add chiller and condenser water bypass pipes. No change. 4) Pumps cycled from intermittent to continuous duty. No change.

Any help is greatly appreciated.
