I just went outside to test my FC. Afterward, I tried to adjust my SWG %, but the controller (Aquapure) no longer seems to respond. I set the % via the Aqualink Z4, and instead of the usual beep afterward to indicate that the change was made, it did nothing. So now the Aqualink shows one percentage and the SWG controller shows another. Also, the SWG controller only shows 'power on.' Usually it shows 'cell on' or 'cell resting' and 'flow.' Also, none of the buttons on the aquapure seem to work.
