Hello again,
good news, I got my database back! By the way, I changed my configuration to back it up automatically...
Anyway, I joined the recipe (the burnt one.. so be careful!) and here's the equipment configuration. I made two, a 20L (half batch) and a 45L (full batch) configuration.

I used the half batch this time because of the belgium style: very high
ABV so not much water Not far from a 45L recipe but with 20L at the
end! Totally hybrid, and not very well adapted, as I said it would be
probably ok with few more liters.
Finally, FG was 1.081 for 20L, but I lost about 5L during the operation (I transfered the mash in smaller kettle (27L) to finish the brewing), so these resulst are not really relevant.
I'll probable make a whole review of all my facilities when all the settings are ok.
See you.
