Installation Guide Air Quality Product Identification Product Overview The CWV2 air quality sensor for living space is for use with BAS controllers designed to accept 4 to 20mA, 0 to 5 Vdc or 0 to 10 Vdc outputs. This sensor measures CO2 levels using a dual-beam, non-dispersive infrared (NDIR) technology. The CWV2 Value sensor with an accuracy of ±40 ppm ±5.5% of measured value, is ideal for bid-spec applications. CWV2 Value Wall Mounted Air Quality Sensor Specifications OPERATING ENVIRONMENT Input Power Class 2; 20 to 30 Vdc, 24 Vac, 50 to 60 Hz Max. Current 45 mA Analog Output Selectable 4 to 20 mA, 0 to 5 V, 0 to 10 V Operating Temp. Range 0 to 50 °C (32 to 122 °F) Operating Humidity Range 0 to 95% RH non-condensing Housing Material High-impact ABS plastic Terminal Block Torque 0.5 to 0.6 N-m (0.37 to 0.44 in-lbf) CO2 TRANSMITTER Sensor Type Dual-beam, non-dispersive infrared (NDIR), diffusion sampling Output Range 0 to 2000 ppm Accuracy ±40 ppm ±5.5% of measured value Repeatability ±30 ppm ±4.5% of measured value Response Time ≤75 seconds for 90 degree step WIRING TERMINALS Terminal Blocks Screw terminals, 18-24 AWG Screw Terminal Torque 0.2 N-m (2.0 in-lbF) max.

CWV2 Installation Guide Dimensions Functions 115 (4.5) 85 (3.3) 24 (0.9) The CWV2 sensor measures CO2 and temperature (if equipped) in a room and provides analog outputs to a controller. 1. Remove the cover from the base at the bottom of the device. 2. Position the sensor base vertically on the wall 1.35 m (4.5 ft.) above the floor with the “UP” arrow facing upward. Locate away from windows, vents and other sources of draft. If possible, do not mount on an external wall, as this may cause inaccurate temperature readings. 3. Pull 18 or 22 AWG cable(s) through the hole in the backplate.
