The Wi-Fi status indicator is a blue LED indicator located on the top-right
corner of the display window.
2. Getting Started
2.1. How to Identify the Status of the Wi-Fi Module
The Wi-Fi Indicator. It is a blue LED indicator located on the top-right
corner of the display window. This indicator should light up after the
device is powered on.
Connection Status. There are three connection status of the Wi-Fi
module:
1) Pairing. The blue light blinks rapidly (about 4 times per second).
The Wi-Fi module is the pairing-mode, and it should generate a 2.4
GHz Wi-Fi band named as “AuberWifi_” and followed by 12
characters consisted of letters and numbers. This is the MAC
address of the Wi-Fi module.
2) Connecting. The blue light blinks slowly (about 1 time per second).
The Wi-Fi module is trying to connect to the Wi-Fi signal it is
instructed to connect to. This can happen right after a user tries to
add the device to the AuberWiFi app, and it can also happen when
the device has lost the Wi-Fi connection if the Wi-Fi signal is weak
or no long exists.
3) Connected. The blue light stays on solid. The Wi-Fi module is
connected to the Wi-Fi signal that it is instructed to connect to.
When you receive a new AW-SYL-2352 controller and power it up for the
first time, the blue indicator should blink rapidly. If the blue indicator is
not blinking rapidly, please see the next section for how to reset the Wi-
Fi module to paring mode.
2.2. How to Reset the Wi-Fi Module to Pairing Mode
Increase the current value of parameter COOL by “4” to reset the Wi-Fi
module to pairing mode. This action will only reset the Wi-Fi module and
it will NOT alter the existing value of the COOL parameter.
Here is a step-by-step instruction of how to do it on the device:
1) Press and hold the SET key for 2 seconds to bring up the
parameter menu.
2) Keep on short-pressing the SET key to scroll down the parameter
list till you see COOL on the top LED window. The value on the
bottom LED window is the current value of the COOL. By factory
default, this value should be 10. The dot in the lower-right corner
should be blinking rapidly.
3) Use the UP arrow key to increase the value by 4 and press the
SET key to confirm the change. In this example, increase the value
to “14” and press SET key to confirm and go to the next parameter.
4) You can press the A/M key and then press the SET key to exit the
menu. Or, you can keep on pressing the SET key till you exit the
menu. Or, don’t touch any key for 10 seconds to let the device
returns to the normal display mode automatically.
5) Now, the blue Wi-Fi status indicator should start blinking rapidly
and the Wi-Fi module should be in pairing mode. If you use check
the available Wi-Fi signals, you should see a signal called
“AuberWifi_xxxxxxxxxxxx”.

3. Adding an AW-SYL-2352 to the AuberWiFi App
Important: The Wi-Fi module in AW-SYL-2352 can only connect to
a 2.4 GHz Wi-Fi network. Please make sure your router has a 2.4
GHz Wi-Fi network.
Important: The Wi-Fi name (SSID) and the password should have
no space (blank).
3.1. Download and Install the Latest AuberWifi App
Please download the AuberWifi app from the Android app store or the
iTune store and install it on your phone. Please grant the permission to
allow the app to access “File and media” and “Location” while using the
app.
3.2. Set the Device to Pairing Mode
Please see the section 2.2 for details.
3.3. Enable the Internet on Your Phone
Please make sure the internet connection on your phone is enabled. You
phone should be connected to the wireless router that you want to use
for connecting the AW-SYL-2352 controller. Please have the Wi-Fi
password ready. You’ll need to enter the password during the paring
process.
3.4. Add the Device to AuberWifi App
a) Please make sure your phone is connected to a 2.4 GHz Wi-Fi
signal from your wireless router. If you have a dual-band router with
both 2.4 GHz and 5 GHz Wi-Fi under the same name (SSID), you
don’t need to worry about which signal your phone is connecting to.
b) Open the AuberWifi App, tap on “add a device” button.
c) The Wi-Fi name (SSID) should have been filled to the first line.
Enter the Wi-Fi password and tap on the orange “Connect Device”
button.
Figure 3. Enter the password and tap the Connect Device button.
d) Please read the pop-up message boxes and tap “CONTINUE”.
Then, the app will take you to the “Internet” Configuration page on
your phone.
e) On the list of available Wi-Fi signals, select the one that starts with
“AuberWifi_”. This Wi-Fi signal is generated by the Wi-Fi module on
AW-SYL-2352 for pairing purpose. No password is needed.
Figure 4. The device will generate a signal with a SSID started with
“AuberWifi_”.
f) Once your phone is connected to the “AuberWifi_” Wi-Fi signal, it
will show that this Wi-Fi signal “can’t provide internet”.
•For users of Android phones,please wait for a pop-up message
from the notification bar on the top of the screen. The message will
remind you that the “AuberWifi_xxxxxxxxxxxx” has no internet
access and ask if you want to stay connected. Please select “Yes”
to stay connected. Otherwise, your phone will automatically switch
to another Wi-Fi signal that may have internet access, which will
cause the pairing process to fail.
Figure 5. For Android phone users, wait for the system notification, tap
on the notification box, and choose Yes to stay connected.
•For users of iPhones, you won’t see this notification unless you
wait for a much longer time. So, don’t worry about this pop-up
message.
Then, click the “Continue” button on the lower-right corner if you
are using an Android phone. Or, simply switch back to the
AuberWifi app if you are using an iPhone.

Figure 6. For Android phone users, click the Continue button to go to the
next step. Or, simply switch back to the AuberWifi app.
g) In the AuberWifi app, the next pop-up message box will ask you to
confirm that your phone has connected to the “AuberWifi” network
generated by the device. Tap CONFIRM to go ahead with the
paring process.
h) Once you tap on the CONFIRM button, the SSID and password will
be sent to the Wi-Fi module on the device so that it can log on to
your wireless network.
i) If the pairing process is successful, the app will return to the app’s
main page and a new AW-SYL-2352 will appear on the list. The
blue Wi-Fi indicator will blink slowly for a few seconds and then turn
to solid. That means the device has been successfully connected
to your router.
j) If pairing is unsuccessful, the app will remain on the Add Device
page. The blue LED may turn to slow-blinking but will not turn to
solid. Please try again and make sure you check if the SSID
wireless signal is strong enough, if the password is correct, and
wait a little bit at step (g) until the “no internet access” notification
appears.

necessarily mean the device is connected to the internet. When it shows
“connecting…”, it doesn’t necessarily mean the device is offline.
Note: The app’s connection status can be affected by a few factors such
as the strength and the quality of the Wi-Fi signal that your phone is
receiving, the electro-magnetic noise in your environment that affect the
wireless connection of your phone, the other tasks or apps that are
running on your phone might affect your phone’s performance, and the
internet traffic between your internet provider to our server. You can try:
a) exit the app and re-open it; b) turn off the Wi-Fi connection on your
phone and try using the mobile data connection; 3) try a different Wi-Fi
network; 4) check if there is any other app could possibly block internet
traffic.
