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.

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.

● Follow Active/Inactive Binary Input Options – If one
of these options is selected, you must then go to the Binary
Input to Follow fi eld (see Figure 44, page 25)—and select
which Binary Input this Relay Output will be associated
with. If the Follow Active Binary Input is selected, this relay
will energize when the selected Binary Input is Active. If
the Follow Inactive Binary Input is selected, this relay will
energize when the selected Binary Input is Inactive. For
example, if the Main Control Method is “Follow Active
Binary Input” and the Binary Input chosen is confi gured
“N/O Contact (Closes for Active)”, then this relay will
be energized when 24 VAC is applied to the binary input
and the N/O contact closes (Active). If the Binary Input
chosen is “N/C (Opens for Active)”, then this relay will be
energized when 24 VAC is removed from the binary input
and the N/C contact opens (Active).
• Follow Active Binary Input • Follow Inactive Binary Input
● Follow Relay Output – If this option is selected, you must
then go to the Relay to Follow fi eld (Figure 45, page 25)
and select another relay that this relay is to follow. For
example, if you are confi guring Relay #1, you can confi gure
it to energize whenever Relay #2 (based on its logic)
energizes.

● Follow Schedule – If this option is selected, you must
then go to the Controlling Schedule fi eld (Figure 43,
page 25)—and select the desired Schedule. This relay
will be energized whenever the selected Schedule is in the
Occupied Mode. See the Setting Schedule Section on page
35 on how to set up Schedules. (This option is not available
with Logical AND/OR operations. See page 26.)
Ventilation Control – If this option is selected, you must
●
then go to “Ventilation Control” at the bottom right of the
Relay Confi guration Screen (Figure 34, page 21). There
you can confi gure a “Vent Mode ON Time” and a “Vent
Mode OFF Time.” This relay will then energize for the
duration of the confi gured “Vent Mode ON Time” and
then will de-energize for the duration of the confi gured
“Vent Mode OFF Time.” You have the option of selecting
a Controlling Schedule for this function to follow. If no
Schedule is confi gured, this relay will cycle continuously
for the Vent Mode On/Vent Mode Off operation. If a
Schedule is confi gured, the Vent Mode On/Off will only
cycle the relay during the scheduled Occupied hours. See
the Ventilation Control description on page 27. (This option
is not available with Logical AND/OR operations. See page
26.)
Lead Relay for Lead/Lag Control – If this option is
●
selected, you can also select a Control Source input in
the next fi eld to be used as a Proof of Operation to allow
switching to the Lag Relay upon a failure. This proof can
either be a binary contact activation or an analog input
level. If your Proof is an analog input level, you can then
confi gure either an Increasing or Decreasing Proof Setpoint
(Figure 39, page 24).
If your Proof is a Binary Input, the Proof Failure is initiated
when the selected Binary Input is “Active” (See Confi guring
Binary Inputs on page 18.)
In the Timing and Alarm Section (Figure 34, page 21) at the
right of the Relay Confi guration Screen (Figure 34, page
21), you can confi gure a Lead/Lag Changeover Interval and
a Proof Failure Timeout Delay. For further information, see
the Lead/Lag description on page 27. (This option is not
available with Logical AND/OR operations. See page 26.)
Control Source Field
Figure 37: Control Source Field
A Control Source needs to be selected anytime you select one of the
Above/Below Control Methods. A Control Source also needs to be
selected anytime you select “Lead Relay for Lead/Lag Control” and
you need a Proof Source to switch to Lag based on a failure condition. If you selected any other option as a Control Method, then the
Control Source fi eld is not applicable and will not be available to
make a selection.
When a Control Source is selected, in most cases you will then need
to confi gure Control Source Setpoints – either as Hi/Lo Setpoints or
as Increasing/Decreasing Proof Setpoints. See the Control Source
Setpoints fi eld (Figure 38 & 39, page 24). In some cases, a Binary
Input could be selected as the Control Source (acting as the Proof
Source) for Lead/Lag changeover. For example, a Binary Input
could monitor a Proof of Flow (POF) Switch. When the POF switch
is closed and the Binary Input is Active, the Lead Relay would be
energized. If the POF Switch opens and the Binary Input becomes
Inactive, the controller would switch to the Lag relay. In this case
the Control Source Setpoints would not be used.
The Control Source Options are shown below:

Section 6: Confi guring Relays
Main Control Method Window
Control Source Setpoints
If the Control Method for this Relay is one of the Above/Below
options, then the Control Source Setpoints need to be confi gured.
See Figure 38 below.
The “High Limit Setpoint” and the “Low Limit Setpoint” establish
the Control Window.
For example, if “On Above/Off Below” is selected as the Control
Method, then the relay will energize above the High Limit Setpoint
and will de-energize below the Low Limit Setpoint. In between is
a deadband.
If “On Above/On Below” is selected as the Control Method, then
the relay will energize above the High Limit Setpoint and below
the Low Limit Setpoint. In between these setpoints, the relay will
be de-energized.
The “ Night Setback Setpoint Spread” is the offset to the High and
Low Limit Setpoints used during the Unoccupied Mode. The Question Mark feature is not used in this case.
Slide Offset Channel Field
If you are using a WattMaster standard OE212 or OE213 Flush Mount
Wall Sensor which has the optional slide offset switch, and you want
that slide switch to adjust the Control Source Setpoints up or down,
be sure to select the analog input the slide offset was connected to
(Control Source fi eld, Figure 37, page 23). See Figure 40 below.
If you are using a Digital Communicating Temperature sensor
(OE217-00) and it is the Control Source, its slide offset will automatically be used if Control Source Setpoints were entered. In this
case, you do not need to confi gure the Slide Offset Channel.
The slide offset effect will be refl ected on the Main GPC-XP Status
Screen in the Setpoints fi eld next to this relay (Figure 8, page 11).
The Hi Limit and Lo Limit Setpoints on this current screen will
always refl ect their confi gured values.
Figure 38: Control Source Setpoints
If the Control Method for this Relay is Lead Relay for Lead/Lag
Control, then the Setpoint fi eld in Figure 39 below will appear:
Figure 39: Control Source Setpoints for Lead Relay
for Lead / Lag Control
The “Increasing Proof Setpoint” would be used if the Control Source
input needs to rise to a certain level to establish Proof of Operation.
The “Decreasing Proof Setpoint” would be used if the Control
Source input needs to fall below a certain level to establish Proof of
Operation. Clicking on the Question Mark will show Help information. Do not enter a value for both setpoints or the Increasing Proof
Method will take control. If the Lead/Lag Proof is a binary input,
these setpoints are not used. The Night Setback Setpoint Spread fi eld
is not available in this confi guration.
Figure 40: Slide Offset Channel
Reset Source/Reset Source Limits Field
You can select an input as the Reset Source (that is, any Source except
the Binary Inputs) that will cause your Control Source Setpoint to be
proportionally reset between the Lo Limit Setpoint and the Hi Limit
Setpoint as the Reset Source changes from its programmed Minimum
Limit to its Maximum Limit. The reset can be made reverse acting
by reversing the Min/Max reset limits so that the Min is the higher
value. See Figures 41 & 42.

Controlling Schedule Field
You can select one of the Internal Schedules to set the occupied or
unoccupied mode of operation for this selected relay. If the relay
does not require a schedule to be part of its control strategy, leave
the selection as “None Selected.” This will cause the controller to
assume it is always “occupied” and therefore always available for
operation. See Figure 43 below.
Main Control Method Window
Relay to Follow Field
If you want this relay to energize at the same time as another relay
(based on that relay’s control logic), select “Follow Relay Output”
in the Control Method fi eld, Figure 36, page 22) and select the
other relay here (Figure 45 below).
Figure 45: Relay to Follow
Figure 43: Controlling Schedule
Binary Input to Follow Field
You can confi gure this relay to energize whenever a selected Binary
Input is Active/Inactive. If the Control Method you confi gured for
this relay is “Follow Active/Inactive Binary Input” (see Figure 36,
page 22 for more detail), you need to select which Binary Input
will cause this relay to energize in the appropriate condition. See
Figure 44 below. The Binary Input does not require a physical
contact closure to become active. It can follow a global broadcast or
some other event as noted in the Binary Input Confi guration section
(pages 18 & 19).
Enabling Relay Field
When confi guring the operation of a relay, an Enabling Relay can
also be selected. The operation of the confi gured relay can only occur
once the Enabling Relay (based on its logic) has energized. For example, a Cool Stage Relay could be prevented from energizing until
a Fan Relay (Enabling Relay) has fi rst energized (Figure 46 below).

Section 6: Confi guring Relays
Logical AND Control Method & Logical OR Control Method
Logical AND Control Method & Logical OR
Control Method
If more than one criterion is required to make a decision to energize
a relay, there are two other options available to use in the decision
process— a “Logical AND” condition and a “Logical OR” condition. If you do not need any additional criterion, simply select the
<Not Confi gured> option under the Control Method for each of
these sources.
If you need two events to be true before the relay output can be
activated, use the Main Control Method in conjunction with the
Logical AND Control Method. If you want either one event or a
second event to activate this relay, use the Main Control Method in
conjunction with the Logical OR Control Method.
You can combine all three options to create a condition where two
events must be true (2 AND Statements) or a 3rd separate event (OR
Statement) must be true to activate this relay.
Confi guration of the Logical And Control Method and the Logi-
cal OR Control Method is similar to the confi guration of the Main
Control Method.

The Logical AND Control Method Window and the Logical OR
Control Method Window are located in the center of the Relay
Confi guration Screen (Figure 34, page 21). See Figures 47 & 48.

Timing & Alarming
The T iming & Alarming W indow (Figure 49 below) is located on the
right of the Relay Confi guration Screen (Figure 34, page 21). The
corresponding fi elds that you need to fi ll out will become available
based on your previous selections.
Lead/Lag Control
If you have confi gured this relay for “Lead Relay for Lead/Lag
Control,” you will also need to set the “Changeover Interval” and
the “Proof Failure Timeout Delay.”
The Changeover Interval is used to toggle the Lag output into the
Lead output once the runtime hours of the Lead output exceed this
amount of time on the Lag output.
The Proof Failure Time Out Delay is the amount of time given for the
“Proof Source” input to become active once the Lead or Lag output
is energized. If this proof is not made within the specifi ed amount
of time, the controller switches to the Lag output in an attempt to
get the controller running and then sets an alarm to fl ag the user that
a failure has occurred. See Lead /Lag information on pages 22-24
for more detail.
Ventilation Control
If you confi gured the relay for “Ventilation Control,” you can set
the “ Vent Mode ON Time” and the “ Vent Mode OFF Time.” This
means that the output is active for the Vent Mode ON Time and then
cycles off for the Vent Mode OFF Time. If the output is not enabled
by a schedule, it will continue to cycle indefi nitely at the On/Off
rate. See additional information on page 23.
Figure 49: Timing & Alarming Window
Delay & Run Times
Once activated, the Relay can be forced to remain “On” for the
“ Minimum Run Time.” Once de-activated, the Relay can be forced
to remain “Off” for the “ Minimum Off Time.” The “ Starting Delay
Period” is the period of time before the Relay is called to activate
and the time it is actually energized.
Run Time Alarming
If the selected relay output is controlling a device that needs periodic maintenance, you can enter a “ Run Time Alarm Delay Period”
that once exceeded generates an alarm. If you need to protect the
equipment, you can select the Disable Relay box, and the relay will
de-activate once this run time has been exceeded. To reset the Run
Time Alarm, you must cycle power or uncheck the Disable Relay
box and then re-check the box.
Relay Output Type
The Relay Output Type Window (Figure 50 below) is located on
the far bottom right of the Relay Confi guration Screen (Figure 34,
page 21). Normally when the relay is On, the output is active. If
you want to reverse that operation and have the output active when
the relay is Off, select the second option.

Control Type
Floating Point Control
Floating Point Control works best on slow changing applications
where the amount of time it would take to drive full on or full off
is not as critical. For faster response, the PID Control method is
recommended.
With Direct Acting Floating Point Control, as the selected Control
Source rises above Setpoint, the Analog Output voltage signal increases to try to maintain the Setpoint. As the Control Source falls
below Setpoint, the Analog Output voltage signal decreases.
With Reverse Acting Floating Point Control, as the selected Control
Source rises above Setpoint, the Analog Output voltage signal decreases to try to maintain the Setpoint. As the Control Source falls
below Setpoint, the Analog Output voltage signal increases.
A Deadband above and below the Setpoint can be confi gured in
which no control signal change is made.
With Floating Point Control, you can confi gure a Calculation Interval
and a Proportional Control Window. See Figure 55 below.
Figure 55: Calculation Settings for Floating Point
Control
Calculation Interval - Determines how often the control signal
calculation is made to try to reach setpoint. Setting this too fast can
cause over-shooting.
Proportional Control Window - Determines how large of a sig-
nal change will occur at each Calculation Interval. The larger the
Proportional Window, the smaller the signal change will be at each
Calculation Interval.
PID Control
PID Control allows Proportional, Integral, and Derivative Rate of
Change Control. With this option, you can confi gure the Proportional
Control Window, an Integral Constant, and a Derivative Constant
as well as the Calculation Interval and PID Derivative Filter. See
Figure 56.
With Direct Acting PID Control, as the selected Control Source rises
above Setpoint, the Analog Output voltage signal increases to try to
maintain the Setpoint. As the Control Source falls below Setpoint,
the Analog Output voltage signal decreases.
With Reverse Acting PID Control, as the selected Control Source
rises above Setpoint, the Analog Output voltage signal decreases
to try to maintain the Setpoint. As the Control Source falls below
Setpoint, the Analog Output voltage signal increases.
Figure 56: Calculation Settings for PID Control
Calculation Interval - Determines how often the control signal
calculation is made to try to reach setpoint. Setting this too fast can
cause over-shooting.
Proportional Control Window - Determines how large of a sig-
nal change will occur at each Calculation Interval. The larger the
Proportional Window, the smaller the signal change will be at each
Calculation Interval.
Integral Constant - Accelerates the movement of the process
towards setpoint and eliminates the residual steady-state error that
occurs with a pure proportional controller. However, since the integral term responds to accumulated errors from the past, it can cause
the present value to overshoot the setpoint value. We recommend to
start with a small Ki and increase it until a small overshoot occurs
and then dial it back.
Derivative Constant - The derivative term slows the rate of change
of the controller output. Derivative control is used to reduce the
magnitude of the overshoot produced by the integral component
and improve the combined controller-process stability. However,
the derivative term slows the transient response of the controller.
Also, differentiation of a signal amplifi es noise and thus this term in
the controller is highly sensitive to noise in the error term, and can
cause a process to become unstable if the noise and the derivative
gain are suffi ciently large. We recommend to start with a small Kd
and increase it until overshoot is reduced to desired point.
PID Derivative Filter - The controller will average this number of
input changes in order to smooth out a fast changing value.
If the Derivative Constant (Kd) is set to “0,” then control will be
the Proportional/Integral (PI). If both the Derivative Constant (Kd)
and the Integral Constant (Ki) are set to “0,” then the control will
only be Proportional.

Setpoint Reset Source
You can confi gure a Setpoint Reset Source that will allow reset of
the Control Setpoints (Figure 59 below). Once a Reset Source is
selected, you will be able to confi gure both a “Max Setpoint” and a
“Min Setpoint” as well as a Max Reset value and a Min Reset value
(Figure 58). As the Reset Source value varies between the Max and
Min Reset values, the Control Setpoint will be proportionally reset
between the Max and Min Control Setpoints. At the Max Reset
value, the Control Source will be at the Max Setpoint, regardless if
it is an inverse relationship.
Figure 57: Control Source
Control Setpoints & Reset Limits
For most applications, only the Max Setpoint and the Deadband will
be used. See Figure 58 below. Unless a Setpoint Reset Source is
selected, the other values in this section will be grayed-out and not
used. In this situation, the Max Setpoint will be the setpoint you are
trying to maintain. The Deadband is the range above and below the
Setpoint in which no control signal change is made.

Figure 59: Setpoint Reset Source
Disabled Mode Offsets
The Disabled Mode Offsets (Figure 60 below) can be used if you
are using an Enabling Relay, an Enabling Binary Input, or a Controlling Schedule. Anytime this output is not enabled by the Enabling
Relay or the Enabling Binary, or is in the Unoccupied Mode (per the
Schedule), these offsets will be applied to the Max/Min Setpoints
to initiate the control operation of this analog output. These would
then act as “Night Setback” type offsets. If these offset values are
‘0’, there will be no Disabled Mode operation.

If this option is used, the Outdoor Air Temperature must be between
these setpoints for this Analog Output to function. See Figure 61
below.
Figure 61: Outdoor Air Enable Setpoints
Controlling Schedule
No matter what Control Method or Control Source has been selected,
each analog output can be confi gured to follow a schedule. See Fig-
ure 62 below. Actual Schedules are set in the Schedules Window.
See instructions on page 35 for setting Schedules.
Enabling Binary Input
An Enabling Binary Input can also be selected (Figure 64 below).
The operation of this Analog Output will only occur once the selected
Binary Input is Active.
For example, if the Binary Input selected is confi gured as “N/O Con-
tact (Closes for Active),” then this Analog Output is enabled when
24 VAC is applied and the N/O Binary Input contact closes (Active).
If the Binary Input selected is confi gured as “N/C (Opens for Ac-
tive),” then this Analog Output will be enabled when 24 VAC is
removed and the N/C Binary Input contact opens (Active).

Alternate Override and Override
Alternate Override
An Alternate Override Source can be selected to override the output
signal of this Analog Output to a fi xed value when a certain condition
occurs (Figure 66 below).
Finally, select the voltage you want to hold this output to based on
the above logic (Figure 68 below).
Figure 68: Voltage
Override & Cancel Override
You can manually override the logic of an Analog Output and force
it to a specifi c voltage. The Override Voltage fi eld defaults to “-1.0”
which means no override.
Right-click in the data entry fi eld in the Analog Outputs Window
(Figure 51, page 28) to open the Override Voltage Box shown in
Figure 69 below and enter an override value. Click the <Enter>
button to save the value. If you enter an incorrect value, click the
<Clear> button to start over. If there is any value in the fi eld, in-
cluding “0” when you click <Enter>, the voltage from this output
will be forced to that value. Canceling the Override will cause the
voltage to go back to its original reading, and the Override Voltage
fi eld will display “-1.0”.

Click the Enabled box beside any Alarm you wish to enable. When
that alarm condition occurs, the
corner of the Main Prism Screen will turn bright red (Figure 80,
page 39 & Figure 6, page 10). This selection will also allow that
Alarm to send out an email notifi cation if your system is set up for
that function. See the Prism 2 Technical Guide for instructions on
setting up email alarm notifi cations.
Due to the quantity of Inputs and Outputs on the GPC-XP, alarms
have been grouped into ”Sensor Input High/Low Alarm Indication”
and “Relay Run Time Alarm Indication.”
The remaining 3 alarm indicators apply strictly to Lead/Lag Relay
operations. The Proof Source Failure indicator isn’t limited to fl ow
monitoring. It applies to any type of proof of operation your Lead/
Lag requires whether it is Temperature, CFM - Airfl ow, PPM – Parts
Per Million content, etc.
If the proof source doesn’t meet the requirements in the programmed
amount of time, the system switches to the standby output and generates the proof alarm and either the Lead or Standby alarm, depending
on which relay caused the condition.
If either or both Lead/Lag Relays generate an alarm, normal operation
can be restored by clicking the
the <R eset Lead/Lag> button will restart the system using the relay

Week Schedule Broadcasts, AVC Setpoints, and AVC Inputs
Week Schedule Broadcasts
The Week Schedule Broadcasts Window (Figure 86 below) located
in the Miscellaneous Settings Screen (Figure 85, page 40) allows
you to broadcast the Schedules of this GPC-XP to other Unit Controllers only on the Local Loop of this GPC-XP or to All Loops of
a multiple loop system. If an option to broadcast is chosen, all (8)
Schedules of this GPC-XP are broadcast. The decision of another
controller to accept a specifi c Schedule is confi gured on the receiv-
ing controller. Schedules cannot be broadcast from one GPC-XP to
another GPC-XP.
Figure 86: Week Schedules Broadcast Window
AVC Setpoints
In the AVC (Analog Value Comparison) Setpoints Window (Figure
87 below) located in the Miscellaneous Settings Screen (Figure 85,
page 40), you can confi gure the controller to broadcast one of the
AVC values so it can be used by another controller(s), such as an
HVAC unit controller or a second GPC-XP Controller.
Select which value to broadcast and select the channel it is to be
broadcast on. You must use an unused channel between 15 and
31, since channels 1-14 are reserved for other broadcasts. (See the
Global Analog Help Screen, page 47).
You can use two GPC-XP Controllers for this AVC function to
allow the use of up to 16 Analog Inputs in the calculation. In this
case, one GPC-XP must be confi gured to broadcast its value on a
selected channel. The second GPC-XP (which will do the fi nal AVC
calculation) must be confi gured to use that same channel to receive
the broadcast from the fi rst GPC-XP. If that fi nal AVC calculation
of the second GPC-XP is to be broadcast to another controller, then
a different channel must be selected for that broadcast.
Normally the selected AVC value is only broadcast on this controller’s Local Loop. If you want the broadcast to be broadcast to all
loops on the system, check “Broadcast to ALL LOOPS.”
AVC Inputs
In the AVC (Analog Value Comparison) Inputs Window (Figure 88
below) located in the Miscellaneous Settings Screen (Figure 85, page
40), select the Analog Inputs that you wish to include in the AVC
functions. Inputs not selected will perform their normal confi gured
function and will not affect the AVC operations.

Rogue Sensor Limits & Reset & Outdoor Air Broadcasts
Rogue Sensor Limits
The Rogue Sensor Limits Window (Figure 89 below) is located in
the GPC-XP Miscellaneous Setpoints Screen (Figur e 85, page 40)
This allows you to remove an AVC sensor value from the AVC Averaging function if it falls outside the range specifi ed by the Above/
Below values in this fi eld. This condition could be caused by a
bad sensor or a space condition that gets out of control for some
reason. A Rogue Sensor Alarm can be generated and requires you
to confi gure “Alarming Enabled” on the Analog Input Confi guration
Screen (see Figure 11, page 13) for each Analog Input included in
the AVC function. The sensor will automatically be re-included
in the AVC Average function if it returns to the acceptable range.
The alarm, however, is locked until it is cleared by clicking on the
<Reset Rogue Sensors> button (Figure 90 below).
Outdoor Air Broadcasts
In the Outdoor Air Broadcasts Window (Figure 91 below) located
in the Miscellaneous Settings Screen ( Figure 85, page 40), you can
confi gure which inputs will be used to read the Outdoor Air (OA)
Temperature and the OA Humidity. These are the values that will
display in the Outdoor Status section of the GPC-XP Controller
Status Screen (Figure 8, page 11).

Alternately, these values can be read as broadcasts from other controllers by checking the “Read OA Broadcasts” option. In this case,
the OA Temperature is always read on Global Channel #2, and the
OA Humidity is read from Global Channel #7.
The OA Temperature and/or the OA Humidity (read from Analog
Inputs on this GPC-XP) or the calculated Dewpoint from those inputs
can be broadcast to other controller(s). To do this, you must select
the channels you want to broadcast these values on. If the OA Temp
and OA Humidity will be used universally on the system, you should
select Channel 2 and Channel 7 respectively. If these are different
values from what are already being broadcast on Channels 2 and 7,
then you need to select different channels to broadcast these values
(using Channels 15-31). To broadcast the OA Dewpoint you would
also need to use a Channel from 15-31.

Daylight Savings Time, Trend Logging, & Reset Defaults
Daylight Savings Time
In the Daylight Savings Time W indow (Figure 92 below) located in the
GPC-XP Miscellaneous Setpoints Screen (Figure 85, page 40), if you
want the Schedules on this GPC-XP to respond to Daylight Savings
Time changes, you must enter the Start and End dates in this fi eld.
Figure 92: Daylight Savings
Daylight Savings Starting Day
This is the date in the Spring when the time clock automatically adjusts itself forward one hour. If you are in a time zone that does not
have daylight savings time or do not want to use this feature, leave
this value at zero. High limit = 1231; Low limit = 0; Default = 0.
NOTE: The U.S. government has the authority to determine
the switch-over dates each year. Currently, the time
changes the second Sunday in March and then
switches back the fi rst Sunday in November.
Daylight Savings Ending Day
This is the date in the Fall when the time clock automatically adjusts
itself backward one hour. If you are in a time zone that does not
have daylight savings time or do not want to use this feature, leave
this value as zero. High limit = 1231; Low limit = 0; Default = 0.
No matter what your Trend Log Interval is, if you want to save Trend
Logs over a longer period of time (beyond the 120 on-board) you
can confi gure Prism 2 to download the Trend Logs your computer

USB cable between the PC and the GPC-XP Controller.
The PC will automatically recognize the device and a
COM port will be assigned.
NOTE: The COM port used must not be greater than
COM9. If the PC assigned a COM port greater than
COM9, please proceed to page 53 to change the USB
COM port.

Changing the COM Port Number
Changing the USB COM Port Number
When your USB Device is fi rst plugged in, it will be assigned a
COM port number to be used for communicating with the Prism 2
software. If the port number is 10 or greater, it needs to be changed
to a value less than 10 to be recognized by Prism 2.
1. Click <Start>, click <Control Panel>, click
<System>, click the <Hardware> tab, and then
click <Device Manager> to get to the Device
Manager Window.
2. Click on the plus sign next to Ports to see all of the
COM ports.
4. To assign a port number less than 10, click on
<Advanced>. The Advanced Settings Window
will appear.
5. In the COM Port Number drop box, select which COM
port you wish to use. Make sure you select a COM port
number that is not currently in use (you can see the ports
in use in the Device Manager Window). Select a port
number that is less than 10.
3. Right-click on “USB Serial Port (COM#)” and select
<Properties>. In the Properties Window, select the
<Port Settings> tab.
NOTE: Windows
that has ever been installed on your computer. So if
there are no available ports below 10, choose a port
number less than 10 for a device listed that you know
you are not currently using.
6. Once you select the correct COM port number, click
<OK> and close any windows opened in the process of
changing the port number. Make note of this number
because you will need it for your Prism 2 setup.
