IAQ Series Indoor Air Quality Detector

Product Information

The IAQ Series is an indoor air quality detector designed to
monitor and control the air quality in indoor environments. It
provides accurate readings of various parameters such as
temperature, humidity, volatile organic compounds (VOC), carbon
dioxide (CO2), formaldehyde (CH2O), and particulate matter
(PM2.5).

Key Features:

Monitors temperature, humidity, VOC, CO2, CH2O, and PM2.5
Provides stable and accurate sensor readings
Includes a backplate with mounting holes for easy
installation
LCD display for convenient monitoring
Supports network configuration for integration into larger
systems

Product Usage Instructions

Before starting the installation, carefully read the
installation instructions provided in the manual. Failure to follow
these instructions may result in product damage.
Ensure that the IAQ detector is not used in explosive or
hazardous environments, with combustible or flammable gases, as
safety or emergency stop devices, or any other application that
could result in personal injury.
Take electrostatic discharge precautions during installation
and make sure not to exceed the device ratings.
The sensor should be mounted 1.5 meters (5 feet) from the floor
of the area to be controlled. Avoid mounting the sensor near doors,
opening windows, supply air diffusers, or other known disturbances.
Also, avoid areas where the detector is exposed to vibrations or
rapid temperature changes.
Feed the control wire through the center hole of the backplate
and mount the backplate to an electrical box using two screws (not
supplied).
Install the sensor module/cover by placing the tabs on the top
of the backplate into slots in the sensor module/cover and snapping
it onto the tabs on the bottom of the backplate. It is recommended
to install the sensor module with power applied, but it can also be
installed without power.
If power is present, the LCD will illuminate after about 10
seconds, and the sensor readings will be displayed. Allow 24 hours
for the sensors to stabilize to obtain accurate readings.
The LCD backlight is set to ON by default. To turn it OFF,
refer to the Network Setup Guide. When the LCD backlight is OFF,
touching the LCD will turn it on for 2 minutes.
For devices with a concealed LCD, the LCD backlight is set to
OFF by default.
To configure network settings, select the menu icon on the top
left of the display and follow the instructions provided in the
Network Setup Guide.
After the initial setup, you can lock the touchscreen during
network setup to prevent unauthorized access. Refer to the Network
Setup Guide for instructions.
If necessary, set the EOL network termination jumper by moving
it to the ON position. The jumper is located under the cover of the
device.

INDOOR AIR QUALITY DETECTOR
IAQ Series – Installation Instructions

INTRODUCTION
The Total Indoor Air Quality Monitor will monitor up to 6 parameters that include Particulate Matter (PM1, PM2.5, PM4 & PM10), Volatile Organic Compounds, Carbon Dioxide, Formaldehyde, Humidity & Temperature and provide either a BACnet® or Modbus signal for connection to a building automation system. The IAQ features a full-colour capacitive touch screen LCD that’s user configurable, a configurable alarm relay output and field replaceable sensor modules. All this housed in a new modern, quick mount enclosure.

WARNING
Read these installation instructions carefully before commissioning the IAQ. Failure to follow these instructions may result in product damage. Do not use in an explosive or hazardous environment, with combustible or flammable gases, as safety or emergency stop devices or in any other application where failure of the product could result in personal injury. Use electrostatic discharge precautions during installation and do not exceed the device ratings.

WARNING
The CO2 sensor incorporates a selfcalibration feature (ASC) to correct CO2 sensor drift. Use the selfcalibration feature for applications where the CO2 sensor is exposed to fresh air (400 ppm) at least 1 hour each day. If the monitored space has 24 hour occupancy or consistently maintains higher or lower levels of CO2, turn off the self-calibration feature and perform a yearly calibration. If you disable the self-calibration feature at installation time without an allowance for the 7 day autocalibration cycle, then perform a manual calibration to ensure the accuracy of the device. To disable the ASC, refer to the Network Setup Guide.

WARNING
This sensor has multiple settings that can be set or adjusted after installation such as parameter ranges, relay settings, display settings, etc. and can only be completed over the Network.
To set or adjust parameters, refer to the Network Setup Guide.

CALIBRATION (CO2 ONLY)
Field calibration can be completed on the CO2 sensor by 2 methods. 1) Using a field calibration kit, CO2 gas and sensor hood (Part# IAQA-CO2HOOD) or 2) By a using a handheld CO2 meter or secondary device as a reference. To perform using a field calibration kit, please refer field calibration instructions. To perform using a handheld CO2 meter or secondary device as a reference follow the steps below.
