Installation and operation
Installation
Manual and QuickStart guide are available in our download center.
The housing should be installed inside a building, must be protected from any water spray and must be used in environnement with less than 80% relative humidity. The product should not be installed in direct heat source (Heater, sunlight, ...) to avoid local heating effects that may alter a global estimation of environmental parameters in the measured room. The product should be installed in a representative position in regard of the required environemental parameters survey. Usualy, it should be installed between 1m50 and 2m50 from floor.
The product has 1 Green Led, 1 Red led, 1RGB led and two "reed switches" as human to machine interface. These elements should positioned as shown below when installing the sensor.
To correctly install the sensor:
- Open the product from the two clips at the bottom using a small flat screwdriver.
- Use the base as a template and obtain horizontality using a level. Then hang the base on the wall using screws or double-sided tape. Thanks to the noticeably light weight of the product, you can use only two screws.
- Once done you can clip back the front, containing electronic parts, on the base.
- Please, DO NOT USE centered holes for the screws as their heads may interfere with the batteries!

Once installed, the two LEDs are visible through the bottom vertical windows and the reed switches ("ILS" marked) can be actuated like simple buttons using a magnet.
Replacing batteries
Batteries should be replaced with lithium-thionyl-chloride (Li-SOCI2) LR6/AA of 2600mAh each (example: SAFT LS14500). Alkaline 1.5V batteries could also be used however the life expectancy will be reduced. The batteries can be replaced on the fly, one after each other, as each battery slot is protected against side overvoltage.
However, operator must carefully avoid any short circuit or electrostatic discharge during battery replacement.
Steps to replace batteries are:
- Open the product from the two clips at the bottom using a small flat screwdriver.
- Use a plastic spludger to extract batteries from their slots and replace them with new ones.
BEWARE that batteries must all be placed in the same direction. Notice the "+" sign on the PCB.
Renew this operation for the 2 other batteries. - Once done you can clip back the front containing electronic parts, on the base starting from upper side.
Batteries replacement principle TODO: When ready insert technical drawing of battery replacement The information in the table below represents how long the batteries can last. It is based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12. Following estimations are given with default reporting configuration and using two 2.6Ah capacity 3,6v AA Li-Ion batteries installed, of which 85% is used. Battery life expectancy : 3 LEDs are available on VAQAOLt. 2 LEDs Green and Red are visible through the down ears of the sensor. These are the usual leds of Watteco sensors giving indication about current "Network status and running modes". One more led (RGB) is available in the front of the sensor mainly used as a "CO2 level visual indicator" and can also be used during "Operator calibration actions" when "Calibration and IAQ button" on the right side of the sensor is used. Network status and running modes HMI (Watteco sensors common behaviour) There are, 1 reed switch (label ILS) and two LEDs to interact with the product: GREEN LED : LoRaNetwork status, mainly working when sensor try to join a network. Standard reports are disabled during this configuration mode. The sensor keeps the AppEUi and DevEUI configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate…) are lost. The sensor keeps the AppEUi and DevEUI configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost. Automatic CO2 Level indicator HMI Below the Default automatic display of current CO2 level. Notice that VAQAOlt gives the visual indication about co2 level on its "IAQ led" according to some tunable parameters like Period or Thresholds. Please refer to "Concentration levels classification attributes" to learn more about that function. User triggered CO2 Level indicator HMI User can require an immediate display of current CO2 level indication by one TAP or one magnet pass or on the right ILS (reed switch) of the sensor. After that the current level will be displayed through 7 blinks with the current CO2 level indication. CO2 Calibration HMI and fresh air calibration selection The calibration can be managed through magnet HMI. During this process the user can, These functions can be actuated by starting the Calibration configuration process with 3 passes on the right ILS (reed switch) with the Magnet. When started the IAQ Led indicator will chase across the 3 colors Orange, Green, Blue during 30s. From there the device is waiting for action selection. The following animation shows a case where the user, looks at current ABC state (First pass => gives Orange so ABC is OFF), then roll over possible actions, and finally actuate an immediate "fresh air calibration" (Green). Once any action is selected, this one will startup about 10s later without any new action (pass) from the user. And notice that any multiple quick passes with the magnet during this selection will interrupt current calibration process. CO2 Calibration HMI : Example of calibration running Below shows a "calibration process running". It can occur after having selected an "immediate fresh air calibration" or "when a periodic ABC is running ". It will then display successively following states: CoDecs are available to decode frames: Downloads All downlink frames have to be sent on port 125 Please, try and see also Watteco Online codecs The VAQA’O device implements many applicative clusters associated to different sensors entries. The associations between measurement functionalities and EndPoints/Clusters are shown below: VAQA'OLt sensors implements a default Batch and Standard configuration that manages all embedded measurements through a periodic reporting of up to 2 frames per hour. This default configuration can be summarized as follow: It records environmental parameters with a 10 minutes max time sampling and sends them once or twice per hour: On VAQAOLt : It monitors critical events on environnemental parameters Any of these configurations can be removed or modified, and some different ones can be set. However, every change made to the default configuration must comply with the legal duty cycle. For example, the most restrictive in the EU is 0.1%, corresponds to approximately 2 frames per hour with the most constrained Spreading Factor : SF12. VAQA'OLt # . All report unconfirmed From this revision VAQA'O sensors has got an alternate default configuration that can be activated instead of default one. In this alternate configuration Batch is not used. Beware that this configuration is more verbose on radio and will drain battery faster. Following configuration commands can be used to swap between default configuration and alternate one: VAQA'OLt Alternate 'No batch' configuration # All report unconfirmed Codecs are available to decode frames: Downloads Please, try and see also Watteco Online codecs Typical VAQA'OLt batch report Input uplink frame to decode: 303480878e3001a70858829068d7846940ca02da798223d0ae09d36e5912c002 Batch attributes : 3 1,10,7,T 2,100,6,H 3,10,6,CO2 Decoding results: (Try it) { Report on case opened (violation) Input frame: 110a000f00551001 Decoded payload: (Try it) {"version": "Frame_Codec_v_1.0.svn5087", "TimeStamp": "2020-03-02 17:01:45.232452"} Alarm on Humidity level getting lower than specified threshold Input frame: 318a0405000021053398b0 Decoded payload: (Try it) {"version": "Frame_Codec_v_1.0.svn5087", "TimeStamp": "2020-03-02 16:58:38.024454"} Alarm on CO2 level getting lower than Thresold Input frame: 318a800c000021023a98b0 Decoded payload: (Try it) {"version": "Frame_Codec_v_1.0.svn5087", "TimeStamp": "2020-03-02 17:06:46.277547"}Autonomy
With the default configuration the sensor will record all significative measurements up to once each 10 minutes and at least once per hour. Then batch reports will be regularly send containing all these last measurements. It may contain several sample for any of the measured parameters (T, H, CO2). Some specific reports/alarms may also be sent because of default configuration (case opening, threshold crossing for Temperature, Humidity, CO2, ...). Due to all these possibly reported information, consumption estimation is based on a periodic transmission in range from 20 minutes to one hour.
