I have 2 Gyre and 2 GIM, one GIM responding to Apex, the other not. When the pump is connected to the GIM it runs until I plug in the cable that connect it to the Apex. I can plug this same cable into the other GIM and it functions, so I ruled out a defective cable. When Pump is disconnected from this GIM status light does not turn red. Is this a bad Module or does it need some type reset. GIM purchased from AquaCave
