outputs, 8 binary inputs, and 8 relay outputs (7 confi gurable). It also
has an on-board BACnet® port for connection to an MS/TP network.
The Controller contains a 2 x 8 LCD character display and 4 buttons
that allow for status and alarm display, force modes, and BACnet®

VCCX2 Controller Technical Guide
Applications
Variable Air Volume Unit
The VCCX2 can control VAV units that are typically designed for
occupied Cooling Mode only, where VAV boxes equipped with reheat
satisfy heating demands in individual spaces. In this application, unit
heat is typically used for Morning Warm-Up. Morning Cool-Down
is also available. The controller can be confi gured to control the
supply fan VFD to maintain a duct static pressure setpoint.
The VCCX2 can also control VAV units that may require occupied
Heating operation to “temper” the outdoor air if it is too cold outside
for the mixed air to maintain the Cooling Supply Air Setpoint.
Constant Air Volume Unit
The VCCX2 can be confi gured for Constant Volume applications,
that are typically Space Temperature or Return Air Temperature
controlled.
The VCCX2 can also be used for restaurant kitchen or lab applications
that are 100% Outdoor Air part of the time and recirculating air part of
the time. A Hood On binary contact closure input forces the VCCX2
to switch to 100% Outdoor Air control based on an exhaust hood
switch activation. The VCCX2 requires Outdoor and Indoor Air
Temperature (and Humidity) Sensors to accomplish this application.
Single Zone VAV
This is a hybrid CAV/VAV application for a unit serving a single
space and using Space Temperature Setpoints to enable Heating
and Cooling Modes. Heating and Cooling are controlled to their
respective Supply Air Setpoints while the supply fan modulates
to maintain the Space Temperature Setpoints. Single Zone VAV
applications can be confi gured for VAV Cooling and either VAV
or CAV Heating. Single Zone VAV operation requires the use of
modulating Heating or Cooling sources.
Space Temperature Control of High Percentage
Outdoor Air Units
This application allows the unit to be confi gured to use the space
temperature to initiate Cooling and Heating Modes on units that
are high percentage outdoor air or 100% outdoor air units. Before
entering the space Vent Mode, the controller will fi rst determine if
the outdoor air temperature is above or below special outdoor air
Cooling and Heating setpoints. If so, the unit will leave stages of
Cooling or Heating on as necessary to achieve a neutral supply air
temperature – thus avoiding dumping very hot or cold air into the
space.
Make-Up Air Unit
The VCCX2 can be confi gured for 100% Outdoor Air control
for Make-Up Air units. All HVAC Modes are determined from
the Outdoor Temperature and Humidity Sensors. The Outdoor
Air Volume should be at least 50% or higher to be confi gured for
Outdoor Air control.
AAON®Return Air Bypass Control
This control scheme can only be used on Constant Volume HVAC
units that are equipped with a Return Air Bypass Damper and that use
Space Temperature and Humidity Sensors as the Controlling Sensors.
AAON® Return Air Bypass Control provides improved moisture
removal capabilities while utilizing internal space loads for reheat by
redirecting Return Air from the upstream side of the DX Evaporator
Coil to the downstream side of the coil during Dehumidifi cation.
Zone Voting
The VCCX2 can be confi gured to be the unit controller in a zone
voting system where the individual zones vote to put the unit into
occupied Cooling or Heating Mode. To be used in this application,
Orion zone controllers must also be used in order to allow
communication between the zones and the VCCX2 Controller. Duct
static pressure control can be accomplished with a supply fan VFD
or a bypass damper.

ASM01695 MODGAS-XWR-1 Controller
The MODGAS-XWR-1 Controller is designed to be used with White Rog-
ers valves only. It will modulate up to two (2) White Rogers gas valves
to maintain a desired Discharge (Supply) Air Temperature (up to four
(4) modulating gas valves may be controlled when a second MODGAS-
XWR-1 Controller confi gured as a slave module). It also controls the
speed of the induced draft fan to maintain proper combustion in the heat
exchanger. The MODGAS-XWR-1 Controller connects to the VCCX2
Controller via an EBC E-BUS cable. Available only from AAON.

control, schedule, and/or monitor equipment such as unit heaters,
exhaust fans, motorized louvers, and other mechanical equipment.
In addition, the GPC-XP provides Lead/Lag start capabilities.
The GPC-XP has 8 confi gurable analog inputs which will accept signals
from thermistor temperature sensors, 4-20mA or 0-5VDC or 0-10VDC
transmitters. Custom formulas created by available math functions and
operators can be used in conjunction with the analog inputs to create a
calculated value to be used and displayed for a specifi c analog input.
The inputs are set for the desired scaling by means of a jumper bar.
An additional input is available for communicating sensors available
from AAON Controls. The GPC-XP also supports 8 wet contact binary
inputs which can be confi gured for either normally open or
normally closed operation. The GPC-XP has 8 relay outputs for on/off
control and 4 analog outputs for proportional control signals.
Highest/lowest/average of the analog input values can be used in the
GPC-XP logic or broadcast to other controllers on the control system loop.
The GPC-XP also has 8 separate 2 events per day schedules
which can be assigned to any input or output for operational control or
alarm recognition based on time of day. These schedules can also be
confi gured to broadcast to other AAON HVAC equipment installed
on the control system loop. Includes: GPCXP Controller.
