Grundfos IO 100 SQFlex Control Box
Does anybody have any experience with the Grundfos SQFlex IO 100 control box? I've got a lead on an old IO100 control box for cheap but want to see if anybody knows the differences between the IO100 and the IO101. They must have upgraded for a reason, but interested to know anybodys experience with the older IO100. All of my experience has been with the newer, IO101. Thank you in advance!
