Chapter 2
Setting Up
The AirAssure™Indoor Air Quality Monitor is delivered fully
assembled and ready to be mounted on an interior wall. Start by
unpacking the device and its contents from the shipping package.
The monitor is intended to be connected to local 2.4 GHz Wi-Fi®to
access all cloud features, but it can be used without Wi-Fi®if needed
as all data is recorded to a pre-installed microSD memory card
accessible from the bottom of the case next to the USB-C port.
A quick start guide is shipped with each instrument. It provides
the necessary steps to configure the Wi-Fi®settings for
connecting the device to a local Wi-Fi®network and will also
guide you through installation.
N O T I C E
As long as a suitable microSD card is installed, the AirAssure™
IAQ monitor will store data on the card whether or not the unit is
connected to Wi-Fi®. TSI®is not liable for corrupt data on the
memory card.
N O T I C E
If connection to the internet is lost, the AirAssure™ device will
buffer and store data onto its internal memory for approximately
14 days (logged at 15 min. intervals), which will then be uploaded
to the cloud once internet connection has been restored. Data
older than that will be available only on the microSD card.
Currently, customers cannot manually upload microSD card data to
the TSI®Cloud. You will be notified on the cloud data if the
AirAssure™ IAQ monitor has trouble writing to the microSD card.
N O T I C E
The monitor does not have the capability to connect to public
Wi-Fi®networks that require a second step of browser
authentication, such as a free public hotel or airport network.
A different network will need to be chosen.

6 Chapter 2
N O T I C E
Some corporate networks require the device MAC address for
security. This can be found on the serial number label of the monitor.
C A U T I O N
NEVER open the monitor when it is powered on or
connected to the power adapter!
The monitor contains very sensitive
sensors that are susceptible to electro-
static discharge (ESD) and ESD
precautions should be followed to
avoid damage.
If using the microSD card only, you can skip the steps below for
connecting the device to a Wi-Fi®network.
Activating a New Device(s)
1. Open the browser on your phone/computer and navigate to
http://www.tsilink.com/.
2. Login using your TSI.com account credentials. If you do not have
a TSI.com account, click on the “Create Account”button and
create a new account.

Setting Up 7
3. Once you are logged in, click on the plus icon in the lower right.
Hovering over it will show “Activate New Device.”
4. Enter the required information into the fields. The serial number
can be found on the back of the device. You can also name the
device, configure its location and whether or not you would like to
make the data public.
5. Click “Done”when finished.
6. Repeat as necessary for remaining devices.
Connecting AirAssure™ Monitor to a Wi-Fi®Network
For best results, set up the device before mounting it in a permanent
location. However, ensure you have good Wi-Fi®strength in the final
location. If access to Wi-Fi® is not available, data will always be
stored on the included microSD memory card.
The AirAssure™ Indoor Air Quality Monitor can be powered by the
USB wall plug power supply and USB-C cable for this part of the
process. It is recommended to complete these steps prior to wall
mounting, as access to the back of the device is required.

8 Chapter 2
1. Remove the power supply, plug adapter kit, and USB-C cable
from its packaging. Select your region’s plug connector and mate
it to the power supply by “snapping” the plug connector into
the adapter.
2. Connect the other end of the USB cable to the USB-C port on the
bottom of the monitor.
3. Connect the USB-A cable end into the power supply and then
plug-in the power adapter to a nearby power outlet.

4. The monitor should turn on as indicated by the light bar on the
front. To connect the monitor to the internet, you first have to
connect to the monitor’s hot spot.
5. Pulse yellow indicates that the monitor is in set up mode as a
Wi-Fi®hotspot. It will remain in this mode for 60 seconds. If
you need more time, simply unplug and plug the monitor back
in again.
