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
Modules must be wired in such a way that the expansion modules and the controller are
always powered together. Loss of power to the expansion module will cause the controller
to become inoperative until power is restored to the expansion module.
