INSTALLATION
1. Select a mounting location with good air circulation. For room installations, mount
the sensor 4 ½ feet (1.4 m) above the oor.
2. Remove the cover. Flush mount the CWV on a wall or on a standard US or European
single gang junction box.
3. Wire the device. Refer to the wiring diagram.
4. Install the cover.

CONFIGURATION
1. If so equipped, select the voltage outputs by jumpering the V Out 1 and/or V Out 2,
as indicated at left (10=0-10VDC, 5=0-5VDC, 3=0-3VDC).
2. If so equipped, select the relay mode by jumpering the Relay 1 and/or Relay 2
function blocks, as indicated at left (Status=sensor condition, 800=800ppm CO2
setpoint, 1000=1000ppm CO2 setpoint).
LED INDICATION
Green - Power applied to device
Red - Error condition for false reading, CO2 concentration > 10,000 ppm, insucient
power, or improperly calibrated sensor.
The red LED briey illuminates for approximately two seconds when the CWV device
is initially powered. It then deluminates, indicating normal sensor operation.

CALIBRATION PROCESS
1. Remove the cover and connect a hose to the plastic port located on the sensing
module.
2. Begin nitrogen gas ow (0 ppm CO2). Use a ow rate of 0.3 to 0.5 liter/minute,
using the Veris AA01 Calibration Kit or equivalent.
3. Push and hold down the calibration button for 8 seconds.
4. Release the calibration button and verif y that the analog outputs are at either 4
mA or 0 V. If the outputs are not showing these values, repeat steps 3 and 4.
