Product Overview
CW2Xxxxx
The CW2 Series of air quality sensors for living space is a flexible multi-sensor platform for use with BAS controllers
designed to accept 4 to 20mA, 0 to 5Vdc or 0 to 10Vdc outputs. CW2 Series sensors are available with three user
interface options: touchscreen, LCD with three buttons and blank. CO2 and temperature sensors are included with
all CW2 Series air quality sensors. Models with VOC sensors and relative humidity sensors are also available.
