You may be implying heat exchanger effectiveness (=actual heat transferred/maximum heat transfer possible)?
As far as I know, there is no way to specify that parameter in Cycle-Tempo. One should compute the exit temperature manually using the effectiveness and input it as TOUT or whichever temperature is not known.
In Boiler component (evaporator), we can specify the boiler efficiency.
In Condenser, again, like in heat exchanger, it is not possible to specify the effectiveness.
