Switching dos pumps

[Deborah Armay]

I changed the purpose of my DOS pumps. One was used for auto water changes and both channels were being used. But the second channel seemed to not be working correctly. I also had another dose that I was using on the first channel for alk replacement. So I changed dose pumps. I recalibrated the pumps and set up a practice auto water change. The water changed only used the first channel (add) and not the second channel (remove). What am I doing wrong? Do I have to reprogram the two pumps and how do I do that? Thanks

How did you change the modules around? :-) Did you use the "replace module" task? That can be done- all your settings and programming will be transferred.

Just check your pumps and verify the program is the correct ones.

I am sorry, it is not clear from your post how exactly you have done this! :-)

I didn’t know there was a replacement task. I will do that. I just disconnected the power source and connecting cable and switched out places and reconnected cables. Thanks
