I think the reason for your chiller water exit temperature varying is because you have a setpoint on the outlet node of the chilled water loop. If you also put one on the chiller outlet node it should stay constant. This might also help keeping the temperature down when it enters your chilled ceiling. My initial thought would be to try a scheduled setpoint on your chiller and see if that helps. Just as an aside, I find when I model chilled ceilings, it helps to put hard values in wherever possible this seems to control them better.
