AAON ® Coil Dual Digital Module
The Dual Digital Module ( OE370-23-DD-C) is a device that enables
and modulates two digital compressors on HVAC Units controlled by
the VCM-X Modular E-BUS Controller ( OE332-23E-VCMX-MOD-
C). The Dual Digital Module will control the digital compressors to
satisfy the cooling, dehumidifi cation, and heat pump requirements of
the VCM-X Modular E-BUS Controller.
The Dual Digital Module connects to the VCM-X Modular E-BUS
Controller. This allows the Dual Digital Module to receive setpoints
and monitor the Supply Air Temperature from the VCM-X Modular
E-BUS Controller.
See Figure 38 below for wiring diagram.
The Dual Digital Module requires a 24 VAC power connection with
an appropriate VA rating.
NOTE: The Compressor Relays on the Dual Digital Module
are used rather than the relay outputs on the VCM-X Modular
E-BUS Controller.
NOTE: For complete information, including the sequence of
operation, refer to the Dual Digital Module Technical Guide.
