Apex DOS pump running the wrong why on Auto water change

[stanleo]

This is weird. I just set up DOS to do auto water changes. Calibration and configuration went perfectly. When I push the button to start the right pump, it runs the way it is supposed to. The tube on the left pumps water in, the tube on the right pumps water out, like it is labeled. When I turn the pump on through the app it acts the same way. But when the auto water change starts, it goes in the opposite direction; the tube on the left pumps water out and the tube on the right pumps water in. Why is this happening and how can I fix it? For the time being I just switched the tubes so the water goes in the right direction for the auto changes but I don't want to leave it like that in case it reverses.

I hope I explained that right.

Good day - see if the post below helps any. Suncrestreef does a good job of talking about it.

Yep that worked like a charm!! Thank you!

My one complaint about Apex, who ever designed the software just assumes everyone has an IT background.
