Ihave this one fermenting right now. Have obviously not tasted it but this was one of the clearest and maltiest worts I've ever made. Have high hopes for this one!
For the decoction I paused the unit just after the 15 minute rest at 65C finished. Pulled 6 liters of thick mash from the malt pipe and heated it slowly to boiling. Boiled for 30 minutes, returned it to the malt pipe and let the unit continue with its mash schedule. the next rest was 30 minutes at 72C.
I stole this mash schedule:

So the programmed steps were:
Mash-in 53C
1st. rest 53C 40 min
2nd. rest 65C 15min
-------------
Pause and pull decoction
Boil for 30 minutes
Return decoction and resume program
-------------
3rd. rest 72C 30min
4th. rest skipped
5th. rest 78C 15min (mashout)
And sparged with 9 liters of 78C water
