installation

Choose a location to mount the sensor. The centerline of the housing must be1.

parallel to the direction of air ﬂow in the duct.

Use the mounting diagram to drill three holes in the duct for securing the sensor.2.

Insert the probe into the hole. Rotate the housing so that the widest surface is3.

perpendicular to the air ﬂow..

Attach the sensor to the duct using sheet metal screws. Make sure that the gasket4.

on the back of the housing is compressed between the housing and the duct for a

secure ﬁt.

Wire the device. See Wiring section.5.

Conﬁgure the system using the menu (CDL only; see Confuguration section).6.

Calibrate using 0 ppm CO2 gas (see Calebration section).7.

NOTE: This product is factory calibrated. The typical CO2

sensor calibration interval is 5 years, dependent on speciﬁc

site installation factors. As of the date of this document,

compliance with ANSI/ASHRAE 62-2001 requires minimum

on-site accuracy veriﬁcation intervals of 6 months, or per

the building operation and maintenance manual. Accuracy

veriﬁcation should be performed using a comparison to a

known reference, or the CO2gas calibration kit available from

Veris Industries as model AA01.

WARNING: CO2sensor calibration requires gas calibration

kit. Performing calibration without gas kit will cause

erroneous readings. Consult factory for calibration kit.

ABC (Automatic Baseline Calibration) is a patented self-calibration feature, which automatically adjusts the CO2sensor to compensate for drift. When ABC is enabled, the

lowest reading within every 24-hour period is recorded and analyzed over a running 7 day or 28-day period. If a statistically signiﬁcant amount of drift is detected, an

automatic correction factor is applied. This enables the sensor to operate within speciﬁcations for the 5-year calibration interval.

NOTE: After changing the ABC settings, the unit will need to be power cycled to have ABC changes take eﬀect.
