Multi controller doing weird things with 6055 nanos

[slojmn]

I unplugged one of my tunze 6055 nanos form the multi-controller box to get my calcium reactor out for cleaning maintenance. When I plugged the nano back into the multi controller it would not work. No lighting up on those ports for that side of the controller. I then unplugged the other 6055 from the other side and plugged in the first one to the working side and it worked fine. I could not get the second Tunze to work on the other side either. I then plugged both into the same side to run on the same program, which they did for a while, then the program switched to the second side of the controller. Does this make sense?? Anyways, it seems the controller is moving back and forth between the two programs but not running the programs concurrently. I can get one Tunze nano to work at a time depending which side of the controller is fired up. How did this happen? This controller has worked as set for 2+ years without issue. Is there a trick to get it to recognize the Tunze on each side of the controller again and run them concurrently?? I only have two nano 6055's running on the controlelr which has the capacity for 4. So I plug one into each side so as to get more random flow on the program. Any help would be appreceiated. I figured it would just return to normal function as soon as I plugged the pump back into the controller. It was only unpugged for a few minutes.

In Interval mode only one side would run at a time. When you disconnect the pumps, the controller loses power and may need to be reprogrammed. I suspect the controller just is in Interval 1 mode.

Ahhh, okay. I will try and re-program it. That seems to make good sense to me. Roger, I am also sending you a PM.
