Why doesn't my flow switch shut my Legacy AC down?



"This issue is the DG5 Controller is not changing the state of the water flow switch, which does not shut the AC unit down. The water flow switch is wired into Digital Input 7 is set to WtrFl2

The solution to this is to go through Factory Setup 1, I/O setup. Set Digital Input 7 (pg4) to WtrFl3."
