Trying to model a reversible chiller scenario. Any help is appreciated.

Will have (2) chillers - 1 dedicated for a CHW loop on load side and the
other for a HW loop on the load side. The chillers will be piped into a
vertical well ground loop for the condenser side.

The CHW loop will serve a few small CHW coils in single zone AHUs.

The HW loop will serve the HW coils in the same AHUs, but also a HW
radiant slab heating system and several heat recovery units (heating
only). The HW chiller is meant to serve as a preheater to the HW loop
as the temp will peter out at 130 (max), while any remaining heat would
be provided by a set of condensing boilers that will maintain the HW
loop at 150.

I've set up a loop to loop heat pump with the condenser loop to the
lake/well option, attached to the CHW loop and attached to the HW loop.
It runs with fatal errors and brings me back to the input screens.

Thoughts?
