Farho NT USB User manual

SETUP
Connect the NT USB to a power source, the red light will turn on.
If this is the rst time you are installing the device (or a factory reset
has been performed), after a few moments the light will change to
purple (steady). The NT USB is in WiFi connect mode.
To connect the NT USB to your WiFi network you will need to have a
phone or tablet.
With the NT USB in WiFi connect mode [Purple light steady] go to
the Wi-Fi settings on your phone or tablet and scan for available Wi-Fi
networks in your environment.
The NT USB in WiFi connect mode generates a network whose name
(SSID) follows the format "MIFarho_xxxx" where "xxxx" is the unique
identier of your NT USB (IDU).
1.1 Installation of the device
1.2 WiFi connect mode
If you want to delete all information from the NT USB and leave it as
it was acquired (except for rmware updates), a factory reset is
necessary.
From WiFi connect mode (steady purple light) or from Congura-
tion mode (ashing purple light) press and hold the button (the light
will alternate between yellow and purple as long as the button is
pressed) when the light turns red you can release the button and the
NT USB will be reset. Once reset the NT USB will reboot.

OPERATING INSTRUCTIONS
Click on the drop-down menu (---) to display the names of the
networks (SSIDs) that have been found in the environment and
select one. You can also enter the name of the network directly in the
"SSID" eld.
Then enter the password of the WIFi network you want to connect to
in the "PASS" eld.
When you have nished entering the values, press the "Save" button
to send them to the NT USB.
If everything is correct, the NT USB will reboot and after a few
moments it will only show a steady green light.
If the WiFi network does not have access to the Internet or for any
other reason the NT USB cannot connect to the remote access
servers, the NT USB will display the No remote mode light code:
solid orange light. The NT USB will operate normally but only if you
are connected to the same WiFi and every so often the NT USB will
reboot.
Connect your phone or tablet to this WiFi network.
Once connected, your phone or tablet should automatically display
the WiFi conguration web page:
To add a new module press the "Add Modules" button, the NT USB
will stand by. Follow the instructions in the manual of the module to
be added to complete the process.
To pair the NT USB you will need to have a compatible phone or
tablet and download the "Farho-Control" app from the app store of
your phone or tablet.
Before starting the process you must check that the phone or tablet
is connected to the same WiFi network that the NT USB is connected
to.
Run the App and accept the terms and conditions. The App will wait
for pairing. At this point we may be asked for permissions to access
the local network, it is necessary to respond armatively to the
request for the App to work correctly.
With the App in standby, press the NT USB button until the light
turns yellow and release. The phone or tablet will show the progress
of the pairing and once nished the initial installation message will
disappear.
In order to be able to control thermal emitters or other equipment it
is necessary to add them to the NT USB.
In the main menu select the type of module to be installed and then
in the tab bar at the bottom of the screen select "Congure".
If you have not created any zone previously or you want to install the
equipment in a new zone, select "Add Zone". If you have previously
created a zone and want to add the equipment to it, select "Edit
Zone".
If you are creating a new zone you must enter a name before adding
modules. Entering the name and pressing "OK" will create the new
zone.

2. Updating the rmware
In order to access new functionalities, corrections and/or improve-
ments it may be necessary to update the NT USB internal program
(rmware).
To update the rmware the NT USB must be in Conguration mode.
To access the Conguration mode, once the NT USB has a steady
green light, press the button and hold it down until the light changes
from yellow to purple. At this point, release the button and the
purple light will start ashing: we are in Conguration mode.
Just press the button again (short press) and the NT USB will start
updating (if there is a newer version). During the process the orange
light will change intensity and turn o every 10%. The update should
not be interrupted.
Once the process is nished the NT USB will restart. The new
rmware version can be found in the help screen of the App.

To change the WiFi network (SSID) or password, the WiFi connect
mode must be forced.
To force the WiFi connect mode, disconnect the NT USB from the
power supply and connect it again while holding down the button.
The module will initially show a red light, press and hold the button
until the light changes to solid purple. At this point the module will
be in WiFi connect mode generating the corresponding network
(MIFarho_xxxx).
Then follow the instructions in section "1.2 WiFi connect mode".
If the NT USB is in No remote mode [steady orange light] check that
the router has access to the Internet, for example by accessing the
Google search engine website with a web browser from a device
connected to the same WiFi network as the NT USB. In case of
problems with Internet access, contact your provider.
If there is no problem with the Internet connection try disconnecting
the NT USB from the power supply, wait a few seconds and recon-
nect it.
Check for a rmware update by following the steps described in "2.
Firmware update".

4.1 What to do if you change the router or the
WiFi password?
4. Troubleshooting
If the problems persist, it may be that the servers are under mainte-

NT USB functionalities will remain operational.
The service will be restored automatically without any action from
the user.
