I am trying to use my tunze ATO by turning it on and off , with desired conductivity range.
tried this but seem like it is not working.

1. set programing logic 4 " always off and conduct decrease "
2. set programing l5ogic 5 " always on and conduct increase "
3. set programing logic 6 " programing logic 4 and programing logic "
4. assign tunze ATO to socket 16 and set as Progaming logic 6
5. conductivity set to 53.0ms hysteresis 0.4

nothing happened when conductivity up to 53.3ms

Please Help

Thanks

Hendrik
