Model question about Iacoveillo(2005)

Hello, everyone! I don’t know whether I should put patient and impatient households’ budget contraint equations in the model part code of DSGE. Can someone help me solve the above question? I have tried twice to download MMB app to find the code of Iacoveillo(2005), but I failed to download the app. So I ask this question here to turn for help.

This is the replication file from the MMB:
