Trying to identify a component on a pool control board.
It's related to the T-Cell functionality of the board, since everything else like sensing, timing, and whatever else works on the board.
Component got water on it, most likely when a not uncommon occurrence of water jetting out from the filter and splashing onto the board eventually got where it shouldn't.
If this feels like Deja Vu, then you're not insane because I've asked this before on \@electronics. I bought parts only to realize the ceramic capacitor I got was too small for me to handle (reading datasheets are important, as it turns out) so the project got back-burner'd until I had time to look at it again. Though I found the original post has been removed due to offtopic and thus all the information I got about it got lost, ergo I'm asking again.
