I created a Variable Speed WSHP programmatically using OS:AirLoopHVAC:UnitarySystem object but the ForwardTranslateAirLoopHVACUnitarySystem code fails to correctly generate the UnitarySystemPerformance:Multispeed object. Inspecting the ForwardTranslateAirLoopHVACUnitarySystem code, it looks like the code is not complete for air-source and water-source variable speed DX coil types. Some of the observations:
- The ForwardTranslator does not set the Number of Speeds for Cooling input field when the cooling coil is Coil:Cooling:DX:VariableSpeed. This VS cooling coil type is not instantiated here.
- The ForwardTranslator does not set the Heating Speed Supply Air Flow Ratio X and Cooling Speed Supply Air Flow Ratio X input fields correctly for :DX:VariableSpeed coils.
The ForwardTranslator flator workks fine for CoilCoolingDXMultiSpeed and CoilHeatingDXMultiSpeed coil types. Is there a known issue for not supporting the air-source and water-source variable speed DX coil types for this translator?
