1. Using the mounting diagram on page 2, or using the housing as a template, mark
and drill the four mounting holes on the duct. The centerline through the housing
must be parallel to the air ow through the duct.
2. Rotate the duct probe so that its widest sur face is perpendicular to the air ow in
the duct.
3. Insert the probe and secure the sensor to the duct with the sheet metal screws
provided, making sure that the provided gasket material is compressed between
the sensor housing and the air duct.
4. Wiring. See wiring diagrams on next page.

CD SERIES
INSTALLATION GUIDE
OPERATION
CD series duct mount CO2 sensors measure the levels of CO2, RH (if equipped), and
temperature (if equipped) of air inside a duct. The CO2 sensor operates within
accuracy specications for an interval of 5 years and can be eld calibrated. The
temperature element is warranted to meet accuracy specications for a period of
5 years. RH equipped models feature a replaceable HS Series humidity element
that is warranted to meet accuracy specications for a period of 1 year. To maintain
accuracy, all vents must remain clear and free of dust, debris, etc.
INSTALLATION
Observe handling precautions for static sensitive
devices to avoid damage to the circuitry which
1. Choose a location to mount the sensor. The centerline of the housing must be
parallel to the direction of air ow in the duct.
2. Use the mounting diagram to drill the four holes in the duct for securing the
sensor.

WIRING
1. Feed control wire through conduit adapter and grommeted compression tting 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 t ting around control wire until sealed.
5. Snap conduit adapter onto compression tting.
6. Refer to specications for power requirements and relay rating.
7. Select mA or Volt output using selector switch.

3. Insert the probe into the hole. Rotate the housing so that the widest surface is
perpendicular to the air ow.
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 t.
5. Wire the device. See Wiring section.
6. Congure the system using the menu (CDL only; see Conguration section).
