I am very sorry to hear, that you have a problem with your AK 20 because of a change in the software.
We have not been informed from the supplier about it, also Indutherm has no information yet and we are investigating now to get at least a new manual for the controller.
I am not entitled to enter Pandora Production any more, since I had a dispute with Mr. Jesper already last year, but I will sent Khun Num to you or my German colleague Mr. Philip to you for clear this matter.
