I have a Tunze 6105 and 6255 connected to a 7096 multicontroller. The issue I am having is with the 6105. When I press feed mode on the multicontroller, both pumps stop as expected. However, when I either allow the time limit to run out, or I manually restart the multicontroller, the 6105 will not restart. Disconnecting it from the multicontroller still doesn't make it start. It isn't until I unplug and plug the power supply back into the junction module that the pump will restart. I have tried switching the pumps on the multicontroller, but still the same issue with the 6105, so I don't think the problem is with the multicontroller. Any suggestions? Since the pump is hard wired to the junction module, I assume it is not replaceable?
