I have a Bullfrog with EOS which is reasonably poweful, I can consume about 6-7 PPM of fc if I run at 24 hour filtration.
The feature I *really* wish the firmware had is the ability to say whether ozone is enabled or disabled for a given filter program. That way if I'm shocking or trying to clear CCs I can hit it hard and filter 24x7 with ozone, but on the flip side if water and filter are clean and I'm going out of town and just trying to circulate water, I can run short filtration cycles with no ozone and not worry about rapid fc depletion while away. Or I can program something in the middle during the week, like a short afternoon no-ozone filtration cycle that gets stuff out of the water before bathing, and a late night filtration cycle with ozone that would help break down any bathing contaminants.
But I guess I'm a nerd like that
I'm contemplating wiring in a cutoff toggle switch that I can velcro into the front panel and have the toggle poke out one of my panel vents. I figure I can even get a DPST lighted switch so that with the neutral an indicator light tells me when it's on, and know that I'm breaking both ends of the connection. Haven't poked around at the EOS generator to look at the voltage parameters I need for the switch though, and whether I would want to ground the switch to make sure a GFI will trip if there is an issue like a loose connector.
