I have a QT with a hang on filter. The EB8 will not turn it off. Same outlet, plug a light in and it works fine. The outlet is configured as a “return pump”. If I manually turn it off, still runs. If I unplug the filter and plug it back in, it’s not on as it should be. If I manually turn it back on the EB8 turns it on. It will just not turn off automatically or manually. As if there is something about the filter that confuses the EB8.
