Some more thoughts:
· WaterHeater:Mixed shows an outdoor air node “HPWHPlantTank OA Node”. This node is not included in your outdoor air NodeList. I do not know if that’s a problem, though.
· Your fan is upstream of the DX coil, so it’s different than the IO Reference example, but I do not think that is a problem.
· The IO Reference discussion for the for WaterHeater:HeatPump says,
I do not think that you have your nodes connected to the plant loop, so perhaps that is the problem.
I cannot spend more time on this problem today, but I hope that I have been some small assistance. I am happy to help as time permits!
