Heat Pump Water Heaters on multifamily buildings

Hello everyone,

Running on a small problem when connecting the DF_Room2D component to the DF_SHW component with a HPWH. Modeling a multifamily building with 15 units, and after connecting the room2d output to the “condition” input from the SHW component, it creates a tree with 225 branches (15 x 15). Is the solution here to just explode the tree and select one of the branches?

I’m trying to understand why this is happening and if it will/will not impact the results of the energy model. Please see screenshots below:
