HydroModeler - DbReader uses VariableName as Quantity ID

jirikadlec2[CodePlex]
I'm trying to build a HydroModeler model using my data and the Hargreaves-Samani ET model component. My problem is: In my data from the quotCentral European Climate Dataquot source, there is one variable name quotTemperaturequot but there are three
distinct variable codes: quotCZSNW:TMAX, CZSNW:TMIN, CZSNW:TAVGquot. These variables (quotquantitiesquot) all have the same VariableName, but they have a different VariableCode and DataType (Maximum, Minimum, Average).

When I edit the quotconnection propertiesquot between DbReader and HargreavesPET, I can only see one quotTemperaturequot Output exchange item. I would expect to see three output exchange items: TMIN, TMAX, TAVG. Attached is the database with my data.

Start with the DbReader output exchange items and the connection-properties view used to connect it to HargreavesPET. Review how the attached database's VariableName, VariableCode, and DataType are represented, then verify that distinct temperature quantities appear separately rather than being collapsed under Temperature. Done means TMIN, TMAX, and TAVG are all selectable output exchange items.
