To learn more about the Heat and Moisture Transfer options in EnergyPlus, you can see the InputOutputReference for

  • HeatBalanceAlgorithm Timestep
  • SurfaceProperty:HeatTransferAlgorithm
  • SurfaceProperty:HeatTransferAlgorithm:MultipleSurface
  • SurfaceProperty:HeatTransferAlgorithm:Construction
  • SurfaceProperty:HeatTransferAlgorithm:SurfaceList
  • SurfaceProperties:VaporCoefficients
  • MaterialProperty:HeatAndMoistureTransfer:Settings
  • MaterialProperty:HeatAndMoistureTransfer:SorptionIsotherm
  • MaterialProperty:HeatAndMoistureTransfer:Suction
  • MaterialProperty:HeatAndMoistureTransfer:Redistribution
  • MaterialProperty:HeatAndMoistureTransfer:Diffusion
  • MaterialProperty:HeatAndMoistureTransfer:ThermalConductivity

These are all available in the PDF or online.

You should definitely read the Engineering Reference on the Combined Heat and Moisture Transfer (HAMT) Model either the PDF or online.

There are also three example files (see the ExampleFiles directory) that use these objects:

  • 1ZoneUncontrolledFourAlgorithms.idf
  • HAMT_DailyProfileReport.idf
  • HAMT_HourlyProfileReport.idf

As far as your original question, I have not tried to convert a file from CTF to HAMT but I think if you can gather all the required inputs and specify the HAMT algorithm, I think that is all you need.
