how do i set the humidity setpoint schedule

edit

i'm facing hard time determining what is the best output variable to use to get the zone load due to Humidifying and dehumidifying. in Previous question that has been asked on this site link text i did as was explained in herelink text. yet i've have no clue how i got these results and what do they represent since i did not set a schedule of my own for humidity setpoint and here is a link to the whole results file CSVlink text. Also i wonder if using any of these variables might also be of any help Regards
