WARNING!!
Observe Polarity! All boards must be wired with GND-to-GND and 24VAC-
to-24VAC. Failure to observe polarity will result in damage to one or more
of the boards. Expansion Boards must be wired in such a way that power to
both the expansion boards and the controller are always powered together.
Loss of power to the expansion board will cause the controller to become
inoperative until power is restored to the expansion board.
