Features
The VCM-X E-BUS series of controllers now consists of the VCM-X
Modular E-BUS Controller and the VCM-X WSHP (Water Source Heat
Pump) E-BUS Controller. The VCM-X Modular E-BUS Controller has
replaced the standard VCM-X Controller. The E-BUS versions of these
controllers now allow the various E-BUS modules to connect directly
to the VCM-X E-BUS Controllers.
Each of these types of controllers has a version applicable to AAON ®
Tulsa units and a different version applicable to AAON ® Coil units. The
following is a breakdown of the different versions:
• AAON ® Tulsa VCM-X Modular E-BUS Controller
(OE332-23E-VCMX-MOD-A) uses software SS1030
• AAON ® Tulsa VCM-X WSHP E-BUS Controller
(OE332-23E-VCMX-WSHP-A) uses software SS1032
• AAON ® Coil VCM-X Modular E-BUS Controller
(OE332-23E-VCMX-MOD-C) uses software SS1034
• AAON ® Coil VCM-X WSHP E-BUS Controller
(OE332-23E-VCMX-WSHP-C) uses software SS1033
These controllers are designed with 7 analog inputs, 2 analog outputs,
and 5 relay outputs. Each VCM-X E-BUS Controller’s input and out-
put capabilities can be expanded with the VCM-X Expansion Module
(OE333-23-EM), the 12 Relay Expansion Module (OE358-23-12R),
and the 4 Binary Input Expansion Module (OE356-01-BI) by means of
a modular cable. Each VCM-X E-BUS Controller can be confi gured for
control of VAV Units (with or without VAV/Zone Controllers), Constant
Volume Units, and Make-Up Air Units. Features include the following:
• Up to a Combined Total of 20 Stages of Heating & Cooling
• Modulating Cooling Output ( Copeland Digital
Scroll™ Compressor or Chilled Water Valve Control)
• Modulating Heating Output ( Hot Water Valve,
Steam Valve, SCR Electric Heat Control)
• Full Integration with the AAON ® MODGAS Modulating
Natural Gas Controller

E-BUS)
Most common HVAC unit control applications can be confi gured using
only the VCM-X E-BUS Controller. If the application requires more in-
puts and/or outputs, optional expansion modules are available to provide
for additional analog, binary, or digital inputs and outputs as required.
The available expansion module confi gurations allow for 4 or 8 ad-
ditional binary inputs, 4 additional analog inputs, 5 additional analog
outputs, and up to 16 additional binary (relay) outputs. The various
expansion modules plug into the VCM-X E-BUS Controller by means
of a modular cable.
