MHGRV-X to AAON Unit Controller Wiring
Communications Wiring
For connection to a VCCX2 or VCB-X Controller, VCCX2 or
VCB-X Expansion Module, and Reheat Expansion Module, use
an E-BUS Cable to connect to the appropriate E-BUS port on
those modules and/or controller.
For all other controllers, including the VAV/CAV, MUA,VCM,
VCM-X, SA, and RNE Controllers, use an I
2
C Cable connecting
to the appropriate I
2
C ports on those controllers.
When connected to an AAON unit controller, the Supply Air
Temperature Sensor is attached to the AAON unit controller.
See Figure 2, this page .
See the SAT Wiring Conditions Table and SAT OPTIONS jumper
settings in Tables 8 and 10, page 21 .
