Controller Dead End How to Set

Just watched a very informative video on how to set the ‘dead end’ on your wfp controller. Having followed the video instructions my controller set auto stop at 38. However, now knowing it can be set manually, I played around with it and discovered that a dead end of 55 suits my system. I’m sure many, if not all of you already knew this. Il post a link anyway as it was very helpful.
