Operation
a. Operating mode
The operating of the ACW-THAQ is divided between different modes:
-Operating mode: this is the default mode when starting the product. In this mode, the module periodically
sends measurements according to the configuration applied (if the product has never been configured, the
factory configuration applies, see Factory settings).
-Deep sleeping mode: this standby mode mainly allows you to put the product to sleep from the time it is put
into service until it is installed on site. In this mode no measurement or radio communication functions are
possible.
-Configuration mode: This mode is active FIVE minutes after exiting deep sleep mode and allows configuration
of the product in Bluetooth using the PC configurator. In addition, radio frames are sent every minute
(therefore five frames) to ensure that the product is properly commissioned. After these five minutes, the
product returns to operating mode and Bluetooth is deactivated (possibility of reactivating it via Downlink).
-Network pairing mode: This mode is active when the product exits deep standby mode and allows pairing to
a network.
-Fault mode: This mode allows the normal operation of the module to be interrupted when a critical event
occurs. The nature of the event can be multiple:
•Empty Battery (less than x% of the maximum battery level)
•Radio module error
•Automated tests errors
•Application error
The entry in the Fault mode is shown by a RED LED blinking of the product.
If the error does not come from the radio module, the product will send 3 radio frames every 24 hours containing the
error code (s) (see Frames format for error codes). In addition, the product will emit a luminous warning depending
on the nature of the event.
Once in this mode, the module must be restarted (by disconnecting and reconnecting the battery or by command in
Downlink) to return to its normal operation.
At any time, it is possible to identify which mode the product is in by bringing a magnet close at least for 2 seconds to
the diamond mark on the case. The product led will light up in one of these colors depending on the mode:
for operating mode
for configuration mode
for deep sleep mode
for fault mode
for network pairing mode

12
ATIM_ACW-THAQ_UG_EN_V1.2
b. Product start-up
In most cases, the ACW-THAQ is started up before delivery (battery packs already connected) and then placed in deep
standby to limit consumption.
To place the product in its operating mode, bring a magnet close to the diamond-shaped marking on the box for 6
seconds. During these six seconds, the product led must flash in WHITE then in GREEN at the end of the six seconds to
indicate that the product is on the way.
The ACW then enters the network pairing phase. During this phase, a FUSCHIA light signal with a fading effect indicates
that the search phase is in progress.
If the connection is successful, the product will emit a light signal depending on the quality of the network:
•GREEN led signal: good network quality
•YELLOW led signal: medium network quality
•ORANGE led signal: bad network quality
•WHITE led signal: no information on the network quality
The module will then enter its operating mode and start feeding information back to the network according to the
configuration.
In the event of a connection failure (in LoRa only the product will go into simple standby and make a next pairing
attempt the following day, if a network is not joined.
WARNING: To have information on the quality of the Sigfox network, it is necessary to provision a Downlink. It is
this that will make it possible to decide on the quality of the network. On startup, the product sends a test Uplink
described in the Classic frame chapter (type of frame 0x02). If a Downlink is provisioned, information on network
quality will then be fed back by the ACW (light signal). If no Downlink is provisioned, then the ACW will always
display the WHITE light signal.
c. Emission of a test frame
When the product is in its operating mode (and only in this mode), it is possible to send a test frame including a
measurement sample (which avoids waiting for the next measurement frame).
To do this, simply bring the magnet closer until the GREEN light signal goes out. The successful sending of the test
frame will be indicated by a CYAN light signal.
d. Deep sleep
When transporting or storing the ACW-MR4, it is best to place it in its deep standby mode to limit unnecessary
energy consumption.
From any operating mode (except fault mode), bring a magnet near the diamond marking on the box for 6
seconds.
During these six seconds, the product led will flash in the color corresponding to the operating mode, then the
end of the sequence will be indicated by a WHITE fade acknowledging that the product has been put on standby.
The magnet can therefore be removed.

13
ATIM_ACW-THAQ_UG_EN_V1.2
e. Radio module activity
Any sending of a radio frame is indicated by three brief GREEN flashes of the LED.
f. Threshold exceeded
When thresholds have been configured using the configurator and the measurement values exceed these thresholds,
the product LED emits a periodic ORANGE flash to notify it.
g. Substitution to the magnet
You can use the push button on the ACW-MR4 card to perform the same actions as the magnet (activate or deactivate
the product, activate / deactivate Bluetooth).
To do this, open the case and exert two simultaneous presses on the push button. A white flashing indicates that the
button now acts as the magnet (button pressed = magnet approached, refer to Product commissioning, Test frame,
Deep sleep above to find out how to use the button).
WARNING: Once the manipulations have been completed, press the button again two times to restore it to its main
function. A white flashing indicate that the manipulation has been successful.
h. Battery passivation
The ACW-MR4 incorporates a battery depassivation feature, to limit the phenomenon of battery passivation during
prolonged phases of deep standby. This feature is automatically activated as soon as the product goes into its deep
sleep mode. The product will then be awakened once a day to start the battery depassivation sequence, then the
product will return to deep standby by itself.
i. Air quality indication
When the product comes into operation, a brief and periodic flashing (every 5 seconds) is emitted to give an indication
of the CO2 concentration in the room.
If the CO2 level is below 400 ppm the flashing is GREEN, between 400 ppm and 600 ppm, the flashing is YELLOW,
between 600 and 1000 ppm the flashing is ORANGE and above 1000 ppm the flashing is RED.
(The values taken here reflect the indications of standard NBN EN 13 779 concerning the ventilation of non-residential
buildings).

ACW configurator
a. Compatible configurator version
For a THAQ with the following application software version:
Use the version of ACW Configurator:
Sigfox: V0.0.1
LoRaWAN: V0.0.1
V5.1.0
Download and install the configuration software setup ’setupACW.exe‘ at:
https://www.atim.com/en/support-2/downloading/
Notes: The product must be in its Configuration mode to be able to be detected by the configurator. To do this, you
must first put the product into deep standby mode (magnet close to 6 seconds), wait about twenty seconds for the
entry into deep standby to take effect, then wake up the product (magnet 6 seconds to new). The product can then
be configured.
When the ACW Configurator is launched, the waiting
window appears on the screen.
Click on "Help" at the top left of the window then on
"About" to display the version number of the ACW
configurator.
Pairing the ACW-THAQ with the configurator can be done in two ways:
⚫By USB: open the case of the ACW-MR4 and connect it to a computer with a micro-USB cable.
⚫By Bluetooth: make sure that Bluetooth is activated
Do not leave the product connected to the configurator (via USB or Bluetooth) unnecessarily,
otherwise the autonomy of the product will be seriously degraded.

ATIM_ACW-THAQ_UG_EN_V1.2
b. ACW-THAQ setup
Emission and sampling period of the frame
The transmission period (1) corresponds to the time interval between each sending of a measurement frame. This
period can be configured from 10 min to 255 h and its default value is 1 hour.
In addition, it is possible to configure the number of samples in a frame (2). Thus, several measurements will be carried
out before the sending of the frame which will contain all these measurements.
For example, with a period of 60 minutes and several samples of 4, one measurement will be taken every 15 minutes
and the 4 samples will be sent in 4 frames every hour. (4 frames because Sigfox product. It would take 2 frames in
LoRaWAN).
Finally, it is possible to apply a redundancy of the data (3), which means that samples having been sent in the frame
n-1, n-2 or n-3 could be sent again in the frame n to the continuation of the new measurement samples (the most
recent sample first in the frame and the least recent last).
For example, for a history depth of 3, the data of the last 2 frames will be sent, in addition to the new data, in the next
frame.
Keep alive frame period
A life frame can be sent periodically (4). This frame will raise the supply voltage of the product.
The value of this period can be configured from 1 hour to 1 month. By default, the value is set to 4 days.

Frame timestamp
It is possible to deactivate / activate the time stamping of all radio frames (5).
WARNING: This option when activated monopolizes 4 bytes in the frame which cannot be used for useful data.
Configuration of the Radio module
The radio module can be configured to pair with a network (Sigfox or LoRaWAN) or to operate in local (or point-to-
point) mode (6). If the local (or point to point) mode is chosen, it will also be possible to configure the frequency band
to be used (which must be the same on the reception module).
Product clock
If the time stamping function is activated, it is essential to configure the internal clock of the product from the
configurator, which will retrieve the system clock from the computer to apply it to the product (7).
Product versions
When connecting to the product, the configurator retrieves all the software versions of the product (product software
and radio module software) as well as the network identifier (8).
Configuration of sensors
Temperature
On the ACW-THAQ, there is an embedded temperature & humidity sensor.
Here are the configuration parameters available for this sensor (9):
-Enabling/disabling of the sensor.
-Temperature & humidity thresholds
-Temperature compensation on two points
The thresholds can be configured by a high and low threshold according to a configurable hysteresis and duration of
overrun. When a measurement reaches a threshold, a radio frame will be sent (see the Alert Frame chapter for details
on the frame format).
In addition, the temperature and humidity values of the sensor are visible in real time when the product is connected
to the configurator (these values are refreshed every two seconds).

17
ATIM_ACW-THAQ_UG_EN_V1.2
Air quality
Two sensors are present for the quality measurement: a first for the measurement of the CO2 concentration, the
second for the measurement of VOCs (Volatile Organic Compounds).
For each one, you will find the following configuration elements:
-Enabling/disabling of the sensor.
-High and Low thresholds configuration.
Also, it is also possible to see in real time the value measured by each of the sensors.
In addition, for the CO2 sensor, it is possible to configure the altitude at which the sensor will be installed to improve
the CO2 measurement, as well as to activate / deactivate the air quality indication via the LED (A note that this light
indication has a small impact on the autonomy of the product).
Configuration validation
After having filled in all the configuration parameters, it is imperative to click on the “Apply to ACW” button to send
the configuration to the product (10).
It is also possible at any time to read the current configuration of the product which will update the parameters on
the configurator or restore the default configuration of the product.

Frame-specific data
We can differentiate three types of frames:
⚫Classic frame; New generation: Very close to the old frames, the difference is that you can activate the
timestamp. These are for example the life frame, the error frame, the response to configuration frames, ... These
last frames are common to all ACWs but, it is also possible to have other independent frames for each ACWs.
⚫Measurement frame; New generation: These frames consist of samples of the different values of each of the
channels that an ACW can read. Beforehand, the number of samples and the depth of the history will be inserted
in the header.
Note: The number of samples and the depth of the history are in common for all the channels of the frame.
⚫Alert frame (threshold crossing); New generation: These frames combine a conventional frame and a
measurement frame. They consist of a header warning that a threshold has been exceeded, followed by samples
of each of the channels for which a threshold has been exceeded.
