i found when bypassing to the tank the pumps would be running at full flow, inturn running the battery down far to quickly and i also found myself replacing these more often. just seems a no win situation.
contacted the company i bought the controller from and they reckon the older digi ones, out of 50 purchased 10 would be no good
that seems way to high in my opinion.
cheers for replys guys, i,m glad im not on my own!!!!
