PREHEAT-X Controller Wiring
The OE377-26-00061 PREHEAT-X Controller (AAON Part No.
V48510) is designed to control fi xed stages of Preheat and optional
modulating Preheat to maintain a desired Preheat Leaving Air
Temperature Setpoint. The PREHEAT-X Controller directly connects
to the VCC-X Controller or indirectly using an E-BUS Expansion
Board via an EBC E-BUS cable. See Figure 33 for wiring.
The following information will be passed between the PREHEAT-X
Controller and the VCC-X Controller:

Leaving Air Temperature Setpoint

Entering Air Temperature Setpoint

Preheat Enable Signal

Leaving Air Temperature Status

Entering Air Temperature Status

Alarm Status

If the communication is interrupted between the
PREHEAT-X Controller and the VCC-X Controller,
the PREHEAT-X controller will be disabled.
For more information, refer to the PREHEAT-X Controller Technical
Guide.
NOTE: If using multiple E-BUS Sensors or Modules, the
E-BUS Hub or Adapter Board may be required.
