In addition to # 24 not working # 22 is also stopped working.This is the second expansion board of three. #6 and #8 as marked on the board have visible damage.The black rectangles look melted.I have very little experience soldering.The board is markedv1.1 07/2013.Are all the boards made the same by the same manufacturer?Is the new 16 zone built better?How often can this be expected.This open sprinkler is now my only controller running my nursery in a desert climate.
thanks rwp
