GPC-XP Controller Technical Guide
Overview
GPC-XP Controller
Overview
The GPC-XP Controller ( OE338-23-GPC-XP) is used for controlling
equipment or processes that cannot be controlled using a standard
HVAC controller.
The GPC-XP provides the fl exibility to control, schedule and/or
monitor equipment such as unit heaters, exhaust fans, motorized
dampers, pumps, and other mechanical equipment. It can also be
used for simple boiler, chiller, or refrigeration applications as well
as to provide lead/lag start function.
The GPC-XP has an on-board CommLink that provides for standalone programming and monitoring via a direct USB connection to
a computer running Prism 2 software. If used on a networked system
that has an external CommLink, this on-board CommLink would
not be used. Alternatively, the System Manager Touch Screen II for
GPC-XP (OE392-10-GPCXP) can be used to
force modes, and set schedules.
The GPC-XP has (8) confi gurable analog inputs which will ac-
cept signals from thermistor temperature sensors or from 4-20mA,
0-5VDC, or 0-10VDC transmitters. The inputs are set for the desired
scaling by means of a jumper bar. 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. An additional modular input
is available for WattMaster communicating sensors.
view status, perform
Features
The GPC-XP Controller provides the following:
8 confi gurable analog inputs
8 wet contact binary inputs confi gured for normally open
or normally closed operation
8 relay outputs for on/off control
4 analog outputs for proportional or PID control signals
E-BUS port for communicating sensors
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
Schedules can be confi gured to broadcast to other
WattMaster HVAC equipment installed on the same
communications loop as the GPC-XP
Can be confi gured using a computer with Prism 2
software installed
The System Manager Touch Screen II for GPC-XP (sold
separately) can be used to view status, perform force
modes, and set schedules.
The GPC-XP has (8) wet contact binary inputs that can be confi g-
ured for either normally open or normally closed operation. Also
available are (8) relay outputs for on/off control and (4) analog
outputs (0-10VDC) for modulating control. Highest/lowest/average
(H/L/A) of the analog input values can be used in the GPC-XP logic
or broadcast to other controllers on the control system loop. These
H/L/A values are referred to in this technical guide as AVC (Analog
Value Comparison) values.
There are (8) separate two events per day schedules which can be
assigned to any input or output for operational control or for alarm
recognition based on time of day. These schedules can also be confi gured to broadcast to other WattMaster controllers on the control
system loop.
NOTE: The internal USB communication port of the GPC-
XP Controller uses a specialized driver (USB Driver
CD-ROM included) that must be installed on your
Windows PC before communication to the device can
be established. To install the USB Driver, follow the
instructions in Appendix B on page 52.
Can be operated Stand-Alone or connected to a
networked system
On-board CommLink for Stand-Alone programming
using a USB connection to a computer running Prism 2
software
NOTE: The GPC-XP Controller contains no user-serviceable
parts. Contact qualifi ed technical personnel if your
Controller is not operating correctly.

Dimensions and Mounting
Environmental Requirements
The GPC-XP Controller needs to be installed in an environment that
can maintain a temperature range between -30°F and 150°F and not
exceed 90% RH levels (non-condensing).
Mounting
The GPC-XP Controller is housed in a plastic enclosure. It is designed to be mounted by using the 3 mounting holes in the enclosure
base. It is important to mount the module in a location that is free
from extreme high or low temperatures, moisture, dust, and dirt. Be
careful not to damage the electronic components when mounting
the module.
See Figure 1 for Controller dimensions (in inches).

Section 1: GPC-XP Wiring & Setup
Communication Settings
Before Applying Power
In order to have a trouble free start-up, it is important to follow a
few simple procedures. Before applying power for the fi rst time, it
is very important to correctly address the controller and run through
a few simple checks.
Communication Settings
Stand Alone Operation
The GPC-XP has an on-board CommLink that is used during StandAlone Operation. When confi gured for Stand-Alone operation, a
computer running Prism 2 software can be connected directly to the
USB port located at the bottom of the GPC-XP for programming
and monitoring. In order to operate in Stand-Alone Mode, two
things need to be set. First, both CommLink Jumpers found on the
upper left hand side of the board need to be set to ON. See Figure
Caution:
Disconnect All Communication Loop Wiring From The
Controller Before Removing Power From The Controller.
Reconnect Power And Then Reconnect Communication
Loop Wiring.
3 below for details. Second, the Baud Rate determined by setting
ADDRESS Dipswitches 7 and 8 needs to be set to OFF/ON. See
Figure 4, page 8 for details.
NOTE: If using the Internal CommLink, you must set up
the USB drivers. See Appendix B, page 52.
Network Operation
The GPC-XP can be confi gured for connection to a networked system
that has an external CommLink. In this case, the on-board CommLink
would not be used. For this confi guration, two things need to be set.
First, both CommLink Jumpers found on the upper left found on the
upper left hand side of the board need to be set to OFF. See Figure
3 below for details. Second, the Baud Rate determined by setting
ADDRESS Dipswitches 7 and 8 needs to be set to OFF/OFF if using a CommLink IV and to OFF/ON if using a CommLink 5. See
Figure 4, page 8 for details.
Note:
The Power To The Controller Must Be Removed And
Reconnected After Changing The Address Switch
Settings In Order For Any Changes To Take Effect.

Controller Addressing and Baud Rate
The GPC-XP Controller is equipped with address switches. When
using Prism 2 to program and confi gure the GPC-XP Controller, you
would enter this address to communicate with the controller. When
the system is to be connected to other HVAC unit controllers on a
communication loop, each controller’s address switch must be set
with a unique address between 1 and 59.

Initialization, Prism 2 Software, and SMTS II for GPC-XP
Initialization
On system power up, there is an approximately 30-second startup
delay where all default setpoints are initialized, LED’s are initialized,
and all outputs are turned off.
When power is fi rst applied, the STATUS1 LED will fl ash intermit-
tently for about 10 seconds. After a short pause, STATUS1 LED
and STATUS2 LED will fl ash out the controller address. STATUS1
LED will fl ash to represent the tens position. STATUS2 LED will
fl ash to represent the ones position. After the controller address is
complete, there will be a short pause while the initialization process
is completed. There will be no controller operation or communications during initialization. After initialization, STATUS2 LED will
continuously fl ash the status code—(1) blink indicates Normal
Operation; (2) blinks indicates a Push-Button Schedule Override
is in effect.
Example of a controller address of 25:
STATUS1 LED will fl ash 2 times. STATUS2 LED will fl ash 5 times.
Prism 2 Software
The next step is programming the controller for your specifi c re-
quirements. Initial programming of the GPC-XP must fi rst be done

Wall Sensor
If the sensor has been confi gured as a Wall Sensor Slide Offset,
and you are using a WattMaster OE212, OE213, or Digital Space
Temperature Sensor with the slide offset function, type the amount
of the desired offset in < Maximum Slide Offset Effect> fi eld and
press <ENTER> to save. See Figure 20 below.
The value you enter is the amount of offset that will be applied to
the Space Temperature Setpoint when the slider is all the way up or
all the way down. At the center slide position, the Offset will have
no effect on the current Space Temperature Setpoints.

Alarm Confi guration
High and Low Alarm Limits can be programmed if the job-site
requires out of range values to notify service personnel. The alarm
limits can be increased at night by the amount of the Unoccupied
Limit Spread. The Alarm Delay Period is the amount of time the
sensor must be outside the limits before an alarm is generated. This
prevents false alarms if the reading temporally exceeds the limit
but then recovers and stays within the limits the remainder of the
time. Type in a value and press <ENTER>. In order for the alarms
to function, the <Alarming Enabled> check box must be checked.
