The SurfaceConvectionAlgorithm:Inside
object only has those four options. Is there a different algorithm that you would rather apply, or do you have specific convection coefficients that you want to apply each timestep?
UPDATE
You can set both inside and outside convection coefficients by timestep using the Energy Management System (EMS) feature of EnergyPlus. You would need to use the following EMS object:
See an example of these EMS objects below.
