Communicating Wiring
This conguration operates as Stand-Alone (Figure 2, page 5) or
communicating with an AAON Unit Controller (Figure 9, below).
This conguration is used to control one modulating valve, which must
be placed on the gas valve 1 header (attached to Heat 1 Relay).
For VCM-X Controllers, use an I
2
C Cable connecting to the appropriate
I
2
C port on the controller.
For all other controllers, use an E-BUS cable connecting to an E-BUS
port on the controller.
NOTE: Up to 3 additional xed heat stages can be used by using
Heat Relays 2, 3 & 4 below. If additional xed stages
are required, these should be congured and wired to the
AAON Unit Controller’s relays.
