Hello!
I'm using type 647 (diverting valve) to provide the inlet liquid flow for type 928 (fan coils used to heat a building). I receive the warning: "A duplicate of type 647 was found in TESS_Hydronics_v.17.2.0164.dll".
I receive a similar message for type 682 which is also included in my project. I get this warnings only when I apply a control signal for the operation of the ventilation fan of type 928.
