Ok so maybe it was my pc. Here is the story. I had a Rk2 that I bought from a RC forum! I decided to purchase a additional new unit from Marine depot along w/2 new ph probes(1 probe each for RK2#1 and RK2#2) Everything arrives and inspects well. Good job Marine Depot! Everything works except the powerheads don't turn off or function w/control. Day #2 lost an additional channel- CF lighting. If you are not up to date w RK2, here is a crash course. Controls 8 outlets through a panel, all 8 channels are programmable and interchangeable. Channels #4 and #8 are relay controlled for halides and lights. If you read the forum you will see the backasswardness of Digital Aquatics explanation.
sorry Mods for the cornfusion! paranoid much?
