Inputs and Outputs
Analog Inputs (Hard-Wired)
Theanaloginputscanbeconguredfor10Kohm,TypeIIItherm-
istor sensors or for user-scaled 0-5 VDC, 0-10 VDC, or 4-20 mA
inputs. Orion communicating temperature sensors, communicating
combination temperature/humidity sensors, or communicating CO
2
sensors can also be used as analog inputs. These communicating
sensors require the use of pre-terminated Orion E-BUS modular
cables. See the next section for details.
Theinitialcongurationoftheanaloginputsisaccomplishedusing
points AV:5 through AV:12. AV:5 is associated with analog input
#1, AV:6 with analog input #2, etc. For each point (AV:5 through
AV:12),abitvaluecanbeenteredtocongurethatinputforthetype
of sensor or signal that will be used on that input. See the BACnet
®
Parameters Table for the available options.
The jumpers next to each input must be set to match the selected
congurationforthatinput.
Once the Analog Input types have been selected, any of those inputs
conguredfor0-5VDC,0-10VDC,or4-20mAsignalscanbescaled
using points AV:13 through AV:20 to set the maximum scaled value
and points AV:21 through AV:28 to set the minimum scaled value
for each input.
Analog Inputs Using Communicating
Sensors
Inadditiontohard-wiredinputs,dierenttypesofE-BUScommuni-
cating sensors may be used as analog inputs with the BGC Controller.
If multiple communicating sensors are used, it may require the use of
anE-BUSAdapter Board or an E-BUSAdapter Hub in order to
provideadditional E-BUSconnection ports.An E-BUS cable is
required to connect either device to the BGC as well as to connect
the sensors to these devices.
ThefollowingOrionE-BUScommunicatingsensorsareavailable
to use with the BGC:
• ASM01819 - Space Temperature Sensor with
Digital Display
• ASM01820 - Combination Space Temperature/
Humidity Sensor with Digital Display
• ASM02221 - Combination Space Temperature/
Humidity Sensor without Digital Display
• ASM01836 - Combination Outdoor Air Temperature/
Humidity Sensor
• ASM01840 - Combination Return Air Temperature/
Humidity Sensor
• ASM01829 - Wall Mount CO
2
Sensor
• ASM01831 - Duct Mount CO

Sensor
The temperature value of a communicating sensor will be displayed
on the appropriate analog input (AI:2 through AI:9). If a combina-
tion temperature/humidity sensor is used, the humidity value of that
sensor will be displayed on the corresponding analog input (AI:10
through AI:17).
A communicating CO
2
sensor value will be displayed on the ap-
propriate analog input (AI:2 through AI:9).
The Communicating Sensor Technical Guides can be downloaded
from www.aaon.com/controlsmanuals under Sensors.
NOTE: The communicating space sensor (temperature only
with display or combination temperature/humidity
with display) is the only communicating sensor that
can be used on multiple analog input addresses. If
multiple space sensors are used, they can be addressed
as address 1 through 8 via the display on the sensors.
Then, using points AV:29 through AV:36, those
sensors can be addressed accordingly on the BGC.
All other communicating sensors can only be used
once per BGC, and can be left at address 1 on the
appropriate point, AV:29 through AV:36.
Binary Inputs
The(8)wetcontact(24VAC)binaryinputscanbereadasOpen(O)
or Closed (On) using points BI:1 through BI:8. See the Appendix

Parameters Table forthecongurationoptions.
Analog Outputs
The (4) analog outputs can be commanded to a voltage value be-
tween 0.0 VDC to 10.0 VDC using points AV:1 through AV:4. See
Appendix A: BACnet

Relay Outputs
The(8)relayoutputscanbecommandedOnorOusingpointsBV:1
