Bryant Zone Perfect relays

[captainminibar]

The OEM manual does not address how the relays function. The ZonePerfect is a 4-zone system control board with six relays, each with a corresponding LED. Does anyone know how they are energized? See attached picture.

you may have better luck posting in the residential forum.

here is a document that may give you a clue, although it is not for 4-zone, but page6 shows the equipment relay connections, not too sure if it will be helpful or not.
