I guess there is not even one single engineer in this world who will know BY HEART which valve at what time and at what temperature or delta-temperature will open or close and in which sequence and so on and so on. This system, at least for me, is just a mystery. But most of the time it's working perfect - if not - don't worry and don't start thinking why and what and which - just do ECAM ACTION
