GPC Plus Controller
Description
The OE331-21 General Purpose Controller Plus (GPC Plus) is used for controlling equipment or processes that
cannot be controlled using HVAC controllers. The Prism computer front end
software is used to interface with the
GPC Plus controller functions. The
GPC Plus Controller provides the flexibility to control, schedule and/or monitor
equipment such as unit heaters, exhaust fans, motorized louvers, etc.. The
GPC Plus has (6) configurable inputs
which will accept signals from thermistor temperature sensors, 4-20mA or 05VDC transmitters or dry contact closures. An additional modular input is
provided for connection of an OE271
static pressure sensor. The GPC Plus
has (5) relay outputs for on/off control
and (2) analog outputs. With the addition of the OE352 2 Slot Expansion
Base Board and (1) OE357 4 Relay
Expansion Board, (4) additional relay
outputs are available providing for a
maximum of (9) usable relay outputs.
The GPC Plus also has (5) separate 2
event per day schedules, each with its
own optimal start functions built in. In
addition the GPC Plus provides lead/lag
start capabilities.

General Purpose Controller
(GPCPlus )
January 31, 2005
Description
The GPCPlus is a controller designed to “fill in the blanks” between standard off the
shelf programs and minor non-standard applications. An example of a non-standard
application might be exhaust fan control, based on building pressure or a simple boiler
enable controller based on schedules or outdoor air temperature.
The remainder of this document will describe the I/O configurations that are possible and
will also include a few sample applications to aid the user in determining if this controller
will meet their specific requirements.
Main Status Screen
The Main Status Screen provides real-time live updates of the current operating
conditions and is used to access the various setpoint and configuration options.
No control takes place until the user “configures” the operation of the GPCPlus. Access
to the various configuration screens is made by a simple left mouse-click on the
individual reading or output status box for each I/O Point. As a general rule, a left click
1
accesses the configuration for the selected item and a right click accesses the force mode
options if any are available.

Analog Input
Configurations
The first five analog inputs and input #7 can be configured in several different ways.
Input #6 can be used for Static Pressure and accepts the standard pressure sensor with the
phone jack connector, available from WattMaster Controls.
The following configurations are available:
1. Thermister Type III Temperature Sensors (Scaled for Fahrenheit)
2. Thermister Type III Temperature Sensors (Scaled for Celsius)
3. 4 – 20ma User Scaled
4. 0 – 5 vdc User Scaled
5. Wall Sensor Slide Offset
6. Binary Contact Closure
7. Read Global Analog Broadcast from another Controller
4
8. Read Global Binary Broadcast from another Controller
9. Sensor #6 can be assigned to read Static Pressure
Each input is separately configured so combinations of any type of input on the same
controller are possible.
All readings can be overridden to specific values for test purposes. All thermister sensors
can also be calibrated by entering positive or negative offsets to be applied to the current
readings. All 4 – 20ma readings can be calibrated if the user has the exact current or
resistance values available for entering in the calibration fields.
Right-Click on the desired analog input reading to access the pop-up menu shown above
and then select the desired function. If you are calibrating or overriding the reading, the
following window will pop-up. Enter the desired calibration offset or specific reading
you wish to force the input to and press the Enter key. The window will automatically
close and send the command to the controller. If you select the Clear Sensor Override
option, a window will not appear but the clear command will be sent to the controller.
- OR -
5
Any or all readings can also be “broadcast” to other controllers on the communications
loop. For example, the Outdoor Air Temperature is broadcast on channel #2 by any unit
that happens to have the sensor attached. If none of the standard package units have the
outdoor air sensor attached, you could attach it to the GPCPlus and select it for broadcast
on channel #2. All other controllers would “hear” the broadcast and use it in their normal
operations. On the other hand, if you are measuring something like return air humidity,
do NOT select channel #2 to broadcast it on, since all the package unit controls are
expecting the outdoor air temperature. If no package controllers exist on your system
then you are free to use any available global channel for broadcast. There are 32 possible
global analog channels and 16 possible global binary channels.
Select global analogs to broadcast readings and global binary channels to broadcast
contact closure (on/off) information.
If you select one of the unassigned channels for broadcast, it is assumed that you have
other GPCPlus units installed that expect to receive information on those channels since
the standard package code does not listen for broadcasts on unassigned channels.
CAUTION: If you elect to broadcast a reading from the GPCPlus to all
other controllers on your installation, be sure to check the
HELP screen to identify which Global Channels have
already been assigned.
Each input also provides high and low alarm limits if the user requires out of range
values to notify service personnel. The alarm limits can be widened at night and they can
also be forced to be out of limits for a user defined amount of time before an alarm
occurs. This prevents false alarms if the reading temporarily exceeds the limit but then
recovers and stays within the limits the remainder of the time.
All readings are user scalable. That means you can display values with ± 1, ± 0.1, ± 0.1±
0.01 or higher resolutions. Just keep in mind that the maximum value that can be sent
from the controller is ±30,000 so if you have scaled your reading to ± 0.001 then the
maximum value you can send is ± 30 with the 3 additional decimal values (30.000).
6
Each input can also have an appendix selected to display with the reading to make them
more user friendly. The possible appendix values are:
• (None) No Appendix Required
• RH% Relative Humidity
• % Percentage
• °F Degrees Fahrenheit
• °C Degrees Celsius
• PPM Parts Per Million
• PSI Pounds Per Square Inch
• “WG Inches of Water Gauge
• “ Inches
• Ft. Feet
• RPM Revolutions Per Minute
• VDC Volts Direct Current
• BTU British Thermal Units
On inputs selected for Binary Input Contact Closure, the user can select Normally Open
or Normally Closed Contacts.
