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.
