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.
