I've tried in vane to get this PDF. After fruitless hours trying to crack this code I had a break through regarding the cycles and the times for each.
It is possible to toggle through each cycle and change their time values. As far as changing the hardness or capacity or other settings in the raindrop menue I guess I'm still waiting for someone to help me out.
I would only do this if you had a power outage or some other reason that changed your settings. If you watch what it is doing or not doing during a full regeneration and list the times that each cycle goes through only then can you determine if the cycle times are wrong.
So if you need to increase or decrease your cycle times if you pm me I'll tell you how.
