Single Modulating Valve No Staging -
Communicating Wiring
This confi guration operates as Stand-Alone (Figure 2, page 5) or
communicating with an AAON Unit Controller (Figure 6, below).
For connection to a VCB-X Controller or VCB-X Expansion Module,
use an E-BUS Cable connecting to the appropriate E-BUS ports on
those controllers.
For all other controllers, including VCM-X or Expansion Modules, use
an I
2 C Cable connecting to the appropriate I 2 C ports on those controllers.
WARNING: Do Not Connect Power To VOUT/Ground
Terminal Block!
NOTE: If additional fi xed stages are required, these should be
confi gured and wired to the AAON Unit Controller’s
relays.
