Hi guys!
I would like to know if it possible with the salinity probe to program something that when the salinity reach 1.025 a pump is activated from a reservor of fresh water to eliminate my ATO?
Thank you

Yes, just be careful. Stray voltage can interfere with the probe..

this is true.

So you recommend me to stay with my ATO?

Yup. I agree with them.
If you relied only on the salinity and the probe misread for a while, you could dump an awful lot of fresh water into your system... Float switch should be much more reliable.
Checking both (and allowing for some margin of error) is even safer

I think using salinity is the best bet, but I also think you should have a failsafe. You don't want to dump too much water in in case something goes awry.
One thing that works well would be switching the source of your ATO based on salinity. RO if salinity is high, SW if salinity is low. This way you still get the benefit of using your switch and backup switch and timeout with the regular ATO function but able to put the right mix in based on salinity.
There's a lot of factors to creating a generic salinity based ato without using float switches or water level expansion...
Maybe in conjunction with the WL expansion would work great, this way you know you won't exceed X% of water in your sump regardless of what the salinity reads...
