b. Assembly and disassembly
The box is mounted on a flat,
vertical wall. Place and fix the back
of the box on the wall following the
direction indicated by the arrows on
the back. Use Ø 5 mm screws.
The holes of the cover must be on
the right side, in the same direction
as the picture on the right.
NOTE IMPORTANTE
Pour mettre le produit sous tension,
appuyez sur le bouton poussoir
pendant 2 secondes, la LED doit
clignoter 3 fois pour indiquer le
passage en mode exploitation.
Match the pivots at the top of the
case base with their respective
locations on the back panel.
To remove both sides, place a
screwdriver in one of the two
mounting areas at the bottom* of
the front panel and press inward
until the base cover is released.
WARNING
It is imperative to open the box from the bottom; opening from the top can damage the circuit.

c. Installation
For best results, it is recommended to install the box without environmental obstruction and to place it at a minimum
height of 1.5m.
The antenna is integrated in the box.
The product should be mounted on a vertical support, or fixed to a wall.
WARNING
Do not install on a metal pole.
The product incorporates a digital temperature and humidity sensor. The values are read according to the period
defined by the network (Downlink). By default, this period is set to a measurement every hour.

ATIM_ACW-THM_UG_EN_V1.3
Operation
The ACW-THM sensor measures a temperature and a humidity rate at the time "t" and sends these data by radio on
the Radio network (Sigfox or LoRaWAN).
In this version, only the periodic mode is available as well as the life frame.
a. Product start-up
On delivery, the product is in storage mode, it only emits these life frames (1 emission every 4 days).
WARNING
To start it, it is necessary to press the push button on the rear panel for 2 seconds (see previous page).
b. Periodic frames
This reading and transmission period is adjustable by the user, with a minimum of 10 minutes.
NOTE
By default this period is set to every hour.
c. Trames de vie
Celles-ci sont émises une fois par jour ou une fois tous les 4 jours.
NOTE
By default, the period for sending life frames is set to once a day
Configuration
There is no USB or Bluetooth connector on this version.
The configuration is done at the factory and can only be changed by Downlink (from the customer's platform).
