It depends if your are using constant flow or variable flow with fixed proportions.
For constant flow:
I believe your application actually warrants using an AirTerminal:SingleDuct:ConstantVolume:FourPipeInduction, for which you'll set the Induction Ratio to $80/20 = 4$. If you don't have a heating coil in your terminal unit, you might have to include one anyway and zero it out, as I believe it's required.
For help and examples:
5ZoneFPIU.idf uses one of these.For variable flow
Maybe try to use a passive chilled beam?

For constant flow:
I believe your application actually warrants using an AirTerminal:SingleDuct:ConstantVolume:FourPipeInduction, for which you'll set the Induction Ratio to $80/20 $\frac{80\%}{20\%} = 4$. If you don't have a heating coil in your terminal unit, you might have to include one anyway and zero it out, as I believe it's required.

Maybe Probably try to use debug your error, using a passive chilled beam?VAV terminal and a ZoneHVAC unit is likely the way to go.
