Hi GHL team,

I want to put my KHD in RAC control mode.

I want to put the kh target to 9 dKH.

I would like to have the best stability in the KH then I need to have a lower variation of kh ... but the default setting of the «*hysteresis*» (deviation of kh needed to make an action) is 1dKH..

Then when my kh is 9 the khd will dose co2 to RAC until kh will rise to 10 and the KHD will make anything until the kh fall to 8.. then the hysteresis will be 2dKH

Is it right ????

I saw a video of a presentation of the KHD and the hysteresis was 0.1 dKH see screen shot :

And the actual setting :

Thanks a lot for your help !!
