My indoor controller is not allowing any changes to made, e.g., date and time change. It has power but there seems to be a communication problem with the outside box. The pool equipment appears to be activating properly: pump came on at 11:30 AM today, lights went out at 9 PM last night, etc.. The wiring from the outdoor box to the inside controller were all connected. I tried resetting the system by pressing the reset and aux 1 buttons on the outside box but that didn't solve the problem. I wonder if my replacing the PC board yesterday morning for the Goldline XL chlorinator controller caused this problem? I thought the chlorinator system was not connected to the indoor controller. If this caused the problem, how do I get the indoor controller to fully function again? Thanks.
