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.
