Product description
Overview
The YO Airflow Pro Dual is equipped with two differential pressure sensors. It can be used to verify
the dirtiness of air filters and control the pressure in air conditioning systems and air blowers. Other
uses include controlling and monitoring airflow and air pressure in fan coil units.

Device sticker placed on the right side of the device enclosure contains information about model,
version, LoRaWAN region and 3 parameters important in case of device identification and
configuration:
-DEV EUI: 64-bit unique device identifier in a LoRaWAN network,
-DEV ADDR: address required to connect via ABP activation type to LoRaWAN,
-BLE MAC: bluetooth physical address.

Internal Temperature and relative internal humidity
Temperature and relative humidity are measured by sensors placed inside the device enclosure.
These measurements can be used to monitor if the device is working in recommended conditions.

Battery condition
Battery voltage is used to monitor its condition – to spot anomalies (like sudden drop) or its current
condition based on voltage drop over time in comparison to initial voltage rating.

Differential pressure
Differential pressure is measured by two separate sensors. One of them provides information about
air pressure before the filter; the second measures air pressure after the filter. Measurements inform
users about airflow and air quality.

SYMBOL
DESCRIPTION
Device is marked with a symbol saying that electrical and electronic
products may not be mixed with unsorted household waste. Remember
that batteries used to power the device must be treated at a specialized
treatment facility.
Remember about possible electrostatic discharge when replacing battery,
connecting input or doing some other operations near inside electronics.
Be careful while handling the device – dropping it may cause damage that will
affect the sensors and other electronics inside.
When installing the device on the wall remember to wear adequate protective
equipment.
To maintain the level of protection device cover screws must be properly
tightened. Device shouldn’t be used without cover.
Any actions inside the device's enclosure (excluding replacing batteries) must
be performed by trained personnel only.
Clean the device only with damp cloth.
Device is intended for outdoor and indoor use. Make sure that device is not
exposed for long term UV rays and in an environment in the immediate
vicinity of water which may flood the device
