PRODUCT IDENTIFICATION
OPERATION
The AQ series design allows customization for a sensor that
meets project requirements for monitoring temperature, CO
and relative humidity. The product can be ordered for outdoor
or duct mount and with a 0-5/10V analog or BACnet RS485
output.
To verify the features see the ‘Product Identication’ section of
the installation manual.

INSTALLATION
AQD (Duct) Installation
1. Drill a 3/4” hole in duct. Install sensor using gasket and
screws provided. The pickup tube will ensure adequate air ow
regardless of air ow direction.
2. Mount unit to duct with supplied screws. Continue to step 3
under general installation.
AQO (Outdoor) Installation
1. Select an outdoor location under an eave on north side of
building away from direct sunlight and rain exposure.
2. Mount product to building with supplied screws. Continue
to step 3 under general installation.
General (both) Installation
3. If installing with a conduit adapter, remove and replace the
factory-installed cable gland.
4. Wire analog (or RS485 for BACnet version) outputs as needed.
5. Apply power to sensor.
6. Tighten cable gland rmly around wires. If installing with a
conduit adapter, seal wire entry to prevent conduit air from
aecting sensor readings or operation.
7. Close lid and tighten screw. Cover must be securely installed
to prevent moisture from entering enclosure.

WIRING
QUICK START MENU
1. Press and hold qand u(left and middle) buttons for 1
second to enter the Quick Start Menu that is adjustable using
the LCD. Screen will display SPt when the menu has been
activated.
2. Navigation and parameters:
• Pressing uadvances to the next menu item.
• If a menu item is visible, pressing either qor pdisplays the
current value.
• If a value is visible, pressing either qor pchanges the value.
Holding qor pfor a time accelerates the value change.
• If a value is visible, pressing qand ptogether sets the value
to the default.
• If a value is visible, pressing ureturns to the menu item list.
SPt Sets the relay turn-on threshold (Closed
above this level); Default: 800
SPhSets the relay turn-o hysteresis (Open below
this level); Default: 100
SCLSets the CO2 concentration scaling (2=
2000ppm (default); 5= 5000ppm, 10 = 10000ppm)
ADjSets the CO2 concentration calibration oset up to +/-
250ppm; Default: 0ppm
CALSets the CO2 auto calibration period
OFF Auto calibration disabled*, 7d 7 days,14d 14 days
(default), 30d 30 days, 60d 60 days
°FCSelects the unit system for displayed temperature
measurements UsRUser dened (default), °FDegrees
Fahrenheit, °CDegrees Celsius
LvLOutput Scaling (analog version only): 5v5.0V full
scale, 10v 10.0V full scale (default)
RUNClose this menu with changes saved and display
parameters.
3. When setup is complete, select RUN or wait for setup mode
to time out.
*If auto calibration is disabled, sensor may experience drift. Use
in areas that are continuously occupied or with concentrated
levels of CO such as greenhouses should consider dual-
channel sensor options. Consult factory for more information.

QUICK START MENU - BACNET
IMPORTANT: The device will not activate the BACnet interface
until the baud rate and the MS/TP MAC address are congured.
If an active RS485 network is not available, congure the device
using the Setup Menu (documented in the ‘AQ Series User’s
Guide’).
Access the auto conguration wizard by removing the front
cover and pressing the q, u, and p(all three) buttons for one
second. After the wizard activates, the display will show CFG.
The wizard automatically advances between each step after a
few seconds. Pressing the ubutton also advances the wizard.
bR The baud rate value can usually be detected from
existing network activity. If no baud rate could be
detected, the display will show ??. If necessary, use q
and pto change the baud rate before advancing.
AdR The device detects the smallest free MAC address on
the local MS/TP subnet from existing network activity.
If the installation requires a specic MAC address,
use qand pto override the detected address. If the
wizard detects that the selected MAC address
conicts with another device, it automatically
advances to the next smallest free MAC address.
After the wizard completes, the device saves the baud rate and
MS/TP MAC address. Additionally, the device adds 665000 to
the selected MAC address and saves the resulting sum as the
device object ID. If the object ID conicts with another device,
use id.1,id.2, and id.3 in the Setup Menu to set a unique
object ID.
The BACnet interface becomes active immediately after the
wizard completes. To recongure the baud rate and MAC
address, use the Setup Menu or run the wizard again.

VISUAL INDICATORS
Each measurement should display in turn.
If a measurement does not appear, the respective sensor
damaged, has been removed from the device, or has been
selected not to appear through the User’s Menu (See ‘AQ Series
User’s Guide’).
BACnet Only:
The baud rate and MAC address must be congured before the
device begins transmitting.
The RX light (receiving indicator) will ash while data is being
received. If the RX light is not blinking, verify the wiring
conguration and wiring connections.
The TX light (transmitting indicator) will ash while data is
being transmitted.
HOME SCREEN
By default, the device displays one measurement at a time,
rotating between measurements every 10 seconds if multiple
sensor options are installed.
If the installer wants to change which values are displayed on
the LCD, access the User’s Menu (See ‘AQ Series User’s Guide’).
TROUBLESHOOTING
Symptom Solution
No output Check wiring. Ensure power supply
meets requirements.
Reading error
Verify unit is located away from
hot/cold sources.
Verify control panel software is
congured correctly.
Verify accuracy of test instrument.
Install insulation behind sensor to
prevent air ow from inside wall.
