What is the IAQ?

The Indoor Air Quality (IAQ) desktop unit displays a variety of air quality measures and alerts you when those measures are out of their defined range.

Requirements

• Building automation system v7.0 or later with the latest cumulative patch installed.
• USB-C power supply (included)
• BACnet/WiFi (if desired to connect to a BAS)

Air quality measures descriptions
See the table below for a description of the air quality measures the IAQ displays.

a result of human metabolism, concentrations within a building are often used to indicate if enough fresh air is supplied to the space. Concentrations between 350-1000 ppm are normal for an adequately ventilated space. Higher concentrations usually indicate a need for more fresh air.
HCHO| This is indoor air formaldehyde. It is gas that comes from many things like smoking, natural gas, building materials, and indoor furnishings. Moderate concentrations can give off a strong chemical odor. As higher concentrations can cause health issues, it is an important gas to monitor. One can expect higher concentrations in newer buildings. Concentrations between 15-50 ppb are normal for an adequately ventilated space.
TVOC| Total Volatile Organic Compounds refer to the total concentration of multiple airborne gasses present in the air. These gasses can come from smoking, natural gas, building materials, and indoor furnishings. As higher concentrations can cause health issues, TVOC becomes an important aspect of air to monitor. One can expect higher concentrations in newer buildings. Normally acceptable levels of TVOC range from 0.3 to 0.5 ppb.
PM2.5| Particulate Matter (PM) is a mixture of solid and liquid particles that are suspended in the air. PM2.5 refers to very small particles that remain suspended in the air longer. Fine dust, spores, and pollen are some examples. Forest fires and smog also contribute to PM2.5 in the air. Normally acceptable levels of PM2.5 range from 10-30 μg/m³. Some people may experience health issues as concentrations rise above 35 μg/m³ and even more health issues above 100  g/m³.

To install the IAQ

Follow the steps below to install your IAQ.

1. Connect the power supply to the IAQ.

2. Configure your WiFi connection (page 3).

3. Follow the installation wizard on the IAQ for the first boot of the device.
   ○ You must select a 4 to 10-digit numerical PIN. Record this PIN, as it will be required to modify the settings later.
   ○ The IAQ automatically locates and connects to your building automation system.

4. Calibrate your CO2 sensor (page 3).

You can now begin using your IAQ.

To configure the IAQ

Follow the instructions below to customize the settings on your IAQ.

To adjust the brightness

Brightness setting

1. Tap the Settings icon .
2. Tap Brightness and move the brightness slider to the desired position.
3. Tap the Back icon when you are finished.

Automatic dimming setting
Automatic dimming causes the IAQ to dim when not in use, and brightens when your hand comes close to the screen.

1. Tap the Settings icon .
2. Tap the Automatic Dimming toggle to turn automatic dimming on or off.
3. Tap the Back icon when you are finished.

To calibrate CO2

Before using your IAQ, follow the steps below to calibrate your CO2 sensor.

1. Tap the Settings icon .

2. Tap the CO2 icon and follow the directions on the device (see below).
   a) Place the product outdoors for five minutes.
   b) Tap Calibration.

3. Tap the Back icon when you are finished.

To set the WiFi and BACnet configuration
NOTES

• The BACnet Device Instance and device name can only be edited with the Access PIN that is set at the first boot of the IAQ.
• The default BACnet Instance is automatically generated on the first boot.
• The BACnet Instance must be a numeric value between 0 and 4,194,302. This number must be unique within the BACnet network or the device will shut down BACnet communications until a unique number is assigned.
• The default name is “IAQ Desktop Sensor”. This field must be populated for BACnet communication to function.

1. Tap the Settings icon .

2. Tap the WiFi icon .

3. Complete the information required, as described below.
   a) Next to WiFi, in Available Networks, select your WiFi network.
   b) Next to BACnet, note that the Device Instance is automatically generated as described in
   NOTES above. You can change the Device Instance once the entire building is assigned BACnet Instance numbers for all devices.
   c) To change the Device name, tap in the field and enter a new name.

4. Tap the Back icon when you are finished.

To change your PIN

1. Tap the Settings icon .

2. Tap the About icon .

3. Click Change Pin and follow the directions on the screen. The PIN must be 4 to 10 numeric characters.
