polarity of OVERTHERM
it's not clear to me what the polarity of OVERTHERM is, I had assumed it was active low; but I think in this application it might be inverted to be active high by configuration of the LM75.
- could you add a text note about the behavriout of this that sheet of the schematic?
(e.g. that if it is the opposite to teh default that it's programmed that way) I could be mistaken though, part of that LM75A datasheet uses "is active" to describe the output without direct reference to what that means for polarity.
