recycling waste separately at the time you dispose of it helps to conserve natural resources
and ensure a recycling process that respects human health and the environment. For more
information on the recycling centre closest to your home, contact your closest local government
office, your local waste management service or the business from which you purchased the
product.
Radio

a. Mounting
ACW-THO modems are fixed on a flat wall using the 4 fixing holes
available at each end of the case. For best results, it is recommended
to install the case without environmental obstruction and to place it
at a minimum height of 2m. For information, the antenna is integrated
into the box. It must be mounted on a vertical support or attached to
a wall.
b. Identification
The product identifier is visible on the outer label on the back of the product, on the inside of the
electronic board and in the status bar of the configuration software.
For LoRaWAN modems the communication keys are automatically given by the network ("Over The
Air Activation", or OTAA pairing).
Each product in the ATIM ACW range has a QR Code label visible either on the side or on the front
of the product.

Operating mode
To turn on the product, switch the switch to the ON
position.
The ACW-THO sensor measures a temperature and
humidity rate at the instant "t" and sends this data
by radio to the associated Sigfox or LoRaWAN
network, depending on the model used.
Two modes of use are available, periodic or eco-
energy.
a. Periodic mode (called « periodical » in the configurator)
For a complete telemetry, a temperature and hygrometry reading is sent periodically and regularly.
This provides a very accurate tracking curve. In this mode each report is sent by the ACW-THO. The
"Sampling period" is therefore equal to the "Statement period".
This period of reading and emission is adjustable by the user, with a minimum of 10 minutes.

10
ATIM_ACW-TH-O_UG_EN_V1.8
Example of periodic mode operation:
On the other hand, because of the regularity of the radio emissions with a potentially high emission
frequency, this mode of operation can prove to be energy consuming and to impact the life of the
batteries.
b. Eco-energy (called « energy saver » in the configurator)
This mode of operation favors energy saving and promotes battery life.
This mode makes it possible to emit a frame only in certain cases:
•If the temperatures recorded are stable: transmission of a frame only after a defined period
(time out).
•If, between two consecutive readings, the variation of T ° C is greater than a maximum
amplitude defined by the user.
•If a warning threshold is crossed: emission of a frame as soon as the temperature read leaves
the comfort zone or when it returns to it.
Example of Eco-energy operating mode:

11
ATIM_ACW-TH-O_UG_EN_V1.8
Phases of operations:
•from 0 to 3 sec: general initialization + USB initialization.
•from 3 to 4 sec: radio initialization.
•from 1 min to 5 min: emission of a test frame every minute.
•at 6th min: emission of a keep alive frame (battery information).
•at 7th min: emission of a temperature / humidity frame.
of operation (periodic or eco-energy) defined by the user
•Life frame emitted once a day or once every 4 days.

ACW configurator
a. Which ACW configurator version to use?
For a TH with the following application
software version:
Use the ACW configurator version below:
Sigfox: V4.06 or lower
LoRaWAN: V4.08 or lower
V3.7.15, or upper
Sigfox: V5.03 or upper
LoRaWAN: V5.10 or upper
V4.0.2, or upper
Download and install the configuration software '' setupACW.exe '' at:
http://www.atim.com/fr/support/telecharger/
When launching the ACW Configurator, the
waiting window appears on the screen.
Click "Help" at the top left of the window
and then "About" to view the version
number of the ACW Configurator.
Then open the plastic case of your ACW-THO module and connect it to your computer with a mini-
USB cable.

13
ATIM_ACW-TH-O_UG_EN_V1.8
b. LoRaWAN network pairing configuration
Only applies to the ACW-THO / LW8 version.
On LORAWAN networks, there are two methods of pairing to allow a module to connect to the
network.
- OTAA (Over The Air Activation):
In this mode, the communication keys are assigned and transmitted by the network each time the
module is started or requested to connect. This is the mode that is set by default.
- ABP (Activation By Personalization):
In this mode, the communication keys used are those shipped from the factory in the module. Each
time the module is started, the same keys are used.
When you connect the ACW-THO / LW8 to USB, the ACW Configurator automatically detects the
factory settings of the module and displays them in the following window:

Once the configuration is complete, do not leave the module connected to USB. This
mode of operation is very energy intensive. When you remove the USB link without
disconnecting the battery, the module resets and automatically returns to normal
operation.
