Please note that in order to implement the new changes and updates, due to the lack of real-estate available
on the board, it was necessary to reverse the Power and Neutral input pin locations over the earlier version
*If the new pin locations are not acknowledged, and the board is wired with reverse polarity, it will default
to M3 mode, and neither heat output will be enabled.*
