Maximum Cable Lengths
Depending upon how many controllers you are connecting to the ZonePRO and whether you
are wiring the ZCs in parallel or serially, there are certain cable length restrictions.
Diagram A shows the maximum cable length for 3 ZCs wired in serial. Diagram B shows the
maximum cable length for 6 ZCs wired in serial. Diagram C shows the maximum length for
each cable run when connecting the ZCs in parallel using a ZC-BOB and the maximum cable
length of the cable between the ZC-BOB and ZonePRO device.
