Any wizards here that can offer safety tips on programming? Setting up a DOS in my basement for AWC to the tank upstairs. I plan on doing the slow all day run. For safety/redundancy would I want a float sensor in the bottom of my NSW Container to prevent continuing to pull out of tank with nothing to replace when I forgot to fill it and then ATO dropping salinity? Any input is helpful. I’m all about bulletproof plans before implementing things that can kill my tank.
