My question is about the pull down internal resistor inside the BCS. Does it matter if it is "closed" for an extended period? This could be months as I normally leave my BCS running. I can shut it off the BCS when I am not using it as it is a hot side BCS ( I have a seperate BCS for fermenting.) only so the DINs would only be on when I am brewing which would be hours. I could also install a toggle for the 5 vdc and shut it off as well.
I have switches between any widget and the SSR for anything that would cause an issue if the SSR failed that I do turn off when I am not brewing.
I actually like the idea of it being "on", so I know that it has power
