I have reviewed all of the water source heat pump posts and implemented everything suggested. I have a boiler and evaporative tower in series on a condensing loop coupled with a water to air heat pump on the air side. I have made sure that the air side is connected to the condenser plant loop. When I run the job, I get errors related to the water-to-air hp not having connections at its nodes. I really could use either a sample open studio file with a wshp modeled or a screen shot of a properly set up air-loop for a wshp system.

I know that their is a script that will set up the system in an idf file, but I prefer to do it within the open studio environment. My email is energyexpert@bellsouth.net
