PRODUCT DESCRIPTION

The FCVC8-R series are intelligent sensors featuring adjustable temperature,
relative humidity and TVOC / CO

eq ranges. Based on this TVOC measurement,

an equivalent CO

level (CO

eq) is calculated. The TVOC concentration is an

accurate indicator for indoor air quality. Based on the temperature and relative
humidity measurements, the dew point is calculated. The used algorithm
controls a single analogue / modulating output based on the measured T,
rH and TVOC values, which can be used to directly control an EC fan or an
actuator powered damper. All parameters are accessible via Modbus RTU.
