OPERATION
The AQW series design allows customization for a sensor that
meets project requirements for monitoring temperature, CO2
and relative humidity. The product can be ordered as stand
alone temperature, CO2/Temperature, RH/Temperature or all-
in-one CO2/RH/Temperature with a 0-5/10V analog or BACnet
RS485 output. This installation manual applies to the Analog
Version AQW sensor with 0-5/10V output.
To verify the features see the ‘Product Identification’ section of
the installation manual. All versions come with temperature as
a standard output. For CO2 and RH sensing, the option must
be added at the factory.
