Hi all ,
So I was trying a higher flow today and put the controller up from 40 to 60 . It said P5 , any who , I tried to calibrate the controller as I last did it in the winter.
After following Ian's video on YouTube, when pressing the enter and it shows 'c 99 ' it kept saying 'err' .
Set the controller to 30 as in video , it ended up being calibrated at 'c 22' . Where have I gone wrong.....
