DCVCX-R
INTELLIGENT AIR QUALITY
DUCT SENSOR
PRODUCT DESCRIPTION
The DCVCX-R are intelligent duct sensors featuring adjustable temperature, relative
humidity and TVOC ranges. The used algorithm controls a single analogue/modulating
output based on the measured temperature, relative humidity and air quality values,
which can be used to directly control an EC fan, an AC fan speed controller or an
actuator powered damper. All parameters are accessible via Modbus RTU.
