VCM-X Modular E-BUS Controller Technical Guide

OVERVIEW

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

• Full Integration with the AAON

MHGRV Modulating

Hot Gas Reheat Controller

• Conﬁ gurable for Heat Pump Applications

• Advanced Dehumidiﬁ cation Capabilities

• Air Flow Monitoring of Outdoor Air, Supply Air,

and Return Air Streams

• Air Flow Control of Outdoor Air Damper

• Single Zone VAV Control

• Primary/Secondary Heating Control

• Adaptive Supply Air Reset

• Micro Channel Condenser Control

Closure On VCM-X Expansion Module

• Conﬁ gurable for AAON

PAC and DPAC Applications

• Heat Wheel - On/Off Control

• Conﬁ gurable for R22 and R410-A refrigerant

• Head Pressure Control (VCM-X Modular E-BUS and

VCM-X WSHP E-BUS)

• Full Digital and Dual Digital Control (VCM-X Modular

E-BUS)

• Water Source Heat Pump Monitoring (VCM-X WSHP

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.
