Have you considered a strictly mechanical set up for top up? If you have room for an elevated container above your sump, a simple mechanical float valve will do the trick without all the electrical hassle..... and it will work even during a power outage. I'm thinking of going that way myself when I set up my next tank with basement sump. Keep it simple with a gravity feed, only one component really to worry about failing, whereas the electrical ATO has all kinds of potential failure modes.
