You can do a water side economizer quite easily on OS with the "HeatExchanger:FluidToFluid" object.
Add this object onto your chilled water loop on the supply equipment inlet node. This way E+ will try to use this object before your chiller to cool.
Next, add this HX to your condenser loop on the demand side. To do this you MUST grab this object from the my model tab on the left, otherwise you will just create two HX that are not connected. Check by clicking on the dots above or below the HX to check it is linked up how you want it to be.
