    Default Problem to set right chiller temp

    Hello,
    I read several time the user manual, but i can't figure out how to properly set nominal value, cooling difference and hysteresis.
    I want my chiller start 28,4 and stop 27,5.
    At moment i set my nominal value to 27,5 , cooling difference 0, and hysteresis 1,0c
    why my temperature swing between 28,4 and 28,1 ...... while the ON temperature is right according to manual ( 27,5+ 5/6*1+0)=28,4 , my OFF temperature is wrong because i expect 27,5 according to my nominal value setting: 27,5 .
    Can anyone explain me ....
