INSTALLATION GUIDE
INSTALLATION
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
would not be covered under the factory warranty.
1. Choose a location to mount the sensor. The centerline of the housing must be
parallel to the direction of air flow in the duct.
2. Use the mounting diagram to drill the four holes in the duct for securing the
sensor.

3. Insert the probe into the hole. Rotate the housing so that the widest surface is
perpendicular to the air flow.

4. Attach the sensor to the duct using the sheet metal screws provided. Make sure
that the gasket on the back of the housing is compressed between the housing
and the duct for a secure fit.
5. Wire the device. See Wiring section.
6. Configure the system using the menu (CDL only; see Configuration section).
7. Calibrate using 0 ppm CO

WIRING
1. Feed control wire through conduit adapter and grommeted compression fitting on
the bottom of the housing.
2. Remove terminal blocks by pulling straight up on the green assemblies.
3. Connect wires as shown and push terminal blocks back in to black receptacles.
4. Tighten compression fitting around control wire until sealed.
5. Snap conduit adapter onto compression fitting.
6. Refer to specifications for power requirements and relay rating.
7. Select mA or Volt output using selector switch.

sensors measure the levels of CO
2
, RH (if equipped), and
temperature (if equipped) of air inside a duct. The CO
2
sensor operates within
accuracy specifications for an interval of 5 years and can be field calibrated. The
temperature element is warranted to meet accuracy specifications for a period of
5 years. RH equipped models feature a replaceable HS Series humidity element
that is warranted to meet accuracy specifications for a period of 1 year. To maintain
accuracy, all vents must remain clear and free of dust, debris, etc.
