Heat Pump Wrapped Condenser cannot be linked to hot water plant loop

edit

I am modelling a Air Source Heat Pump Water Heater as a DHW system. When I selected the "Water Heater: Heat Pump: Wrapped Condenser", I found it cannot be linked to the hot water plant loop. However, if I use "Water Heater: Heat Pump" which is Pumped Condenser, I can link it to my plant loop. So I tried the drag and drop option to link the "Water Heater: Heat Pump: Wrapped Condenser" Stratified Tank with the plant loop in the HVAC System tab. It works but I found that the heat pump is not working, all the load requirement is fulfilled by the Stratified Tank heating element. Is there any method that I can put the Wrapped Condenser Heat Pump into my plant loop in OpenStudio?

Thank you for your great help in advance.
