For systems with
5 to 8-Zones:
Connect two SmartZone-4X Controllers
together using only a CAT 5 cable.
(Wiring detail shown to right -
same for
primary and secondary controller
)
If two separate transformers are
used for a SmartLINK application
(using two 4X Boards to create 8
zones), the primary and secondary
polarity MUST be the SAME on both.
