A couple of things I learned whiel dealing with the same frustrations.
1. All of your adjustments need to be made in Cel. Although you can switch the view to F, make the adjustments in Cel.
Now,
Look under 3.7.8 Hysteresis on pg 22, there is a formula in one of the paragraphs that explains how to get the chiller to turn on at a certain temp based on your nominal temp.
That is...
T= Nominal Temp + 5/6*Hys + cooling Diff.
One thing important to notice that the Hys value is multiplied by 5/6, so, a Hys of .2C is really only .167C. This may be affecting your calculations.
Plug your desired temp needs, in Celsius, into this equation and you should be better able to get what you need .
