Selecting the Location
The conditions at the location should represent well the area of
interest. Do not install the transmitter on the ceiling. Avoid
placing the transmitter near heat and moisture sources, close
to the discharge of the supply air ducts, and in direct sunlight.
Plan the routing of the cable when selecting the location. You
can bring the cable to the transmitter from above, or from the
center opening of the mounting base.
When bringing a cable through the wall, note that the hole
may also supply air from outside the room into the
transmitter. This may affect the measurement readings. For
example, fresh concrete binds CO
2
and may cause low
readings, especially in new buildings. Seal the cable opening
if necessary.
EN
8
Opening and Closing
To open, use a screwdriver to push down the tab that holds
the transmitter cover and mounting base together. Pull the
mounting base away from the cover, starting from the top.
To cl
ose, connect the bottom of the transmitter first, and tilt the
top forward to close the tab. Do not push on the screen.
Closing the transmitter starts it up if power is supplied to the
screw terminals.
Installing the Mounting Base
Use the mounting holes to attach the mounting base securely.
Use at least two screws (not included). The arrow on the
mounting base must point straight up after installation.
Proper orientation is important: air must flow through the
vents on the bottom and top.

General Wiring Instructions
When wiring, observe the terminal label on the mounting base.
Maximum wire size is 2 mm
2
(AWG14).
If the cable between the sensor and the
controller is over 3 meters, it should be shielded.
The shield would be connected at the controller
end of the cable.
Keep high and low voltage wiring separated.
When using multi-stranded wire apply a cable
ferrule to the cable end.
You can bring the cable to the
housing from above or from
behind (recommended).
If you are wiring a
CD-WAx-00-2 series
transmitter from above, use a
< Ø 5 mm cable, and route it
from the left side of the
mounting base.
11
Wiring CD-WAx-00-2
Recommended wiring for long cables:
-Vs ter
minal is internally connected to GND terminal, so you
can also use the -Vs terminal as common ground. Maximum
cable resistance is 2.5 (24V supply, 0 ... 10 V output):

Transmitter Startup
When the transmitter is powered on, it
displays a sequence of information screens.
The screens are shown for a few seconds
each.
The first screen identifies the transmitter and
the connected measurement modules,
and shows if the transmitter is operating
normally (status OK) or if there is an error
(status ERROR).
The following screen(s) show the
configuration of the analog output channels.
After the startup screens the transmitter
shows the measurement screen. It shows
the measured parameters and currently
active indicators.
It is normal for CO
2
measurement to read
0 ppm for a few seconds after the startup.
EN
14
Trimmer Adjustment (T)
Before starting the adjustment, compare the
reading of the transmitter to a calibrated
reference instrument so you know how much
adjustment is needed. You can use, for
example, the HM70 hand-held humidity and
temperature meter.
To enter the adjustment screen, rotate the
trimmer slightly during normal measurement.
If the trimmer is not centered, you see the
trimmer centering screen first. Simply turn the
trimmer to the center and wait for the
progress bar to complete.
In the adjustment screen, turn the trimmer to
set the desired correction. To commit the
change, stop turning the trimmer and wait.
If you wish to apply a greater correction than
allowed by the trimmer in a single adjustment,
re-enter the adjustment screen and apply a
new correction. Corrections applied using the
trimmers are cumulative.
15
Trimmer Adjustment (CO
2
)
Transm
itter models with CO
2
measurement
have an inlet for calibration gas. Supply the
calibration gas with a known concentration
(for example, 1000 ppm) to this inlet using a
3 mm inner diameter silicone tube and a
0.4 l/min flow.
Turn on the gas flow and wait for three
minutes for measurement to stabilize. If you
are adjusting without calibration gas, avoid
breathing on the transmitter. You should only
adjust the transmitter when the CO
2
reading
is stable.
Rotate the CO
2
trimmer slightly during
normal measurement. If the trimmer is not
centered, you see the trimmer centering
screen first. Simply turn the trimmer to the
center and wait for the progress bar to
complete.
In the adjustment screen, turn the trimmer to
set the desired correction. To commit the
change, stop turning the trimmer and wait.
The transmitter will show with a text screen if
the adjustment was successful, or failed due
to an unstable CO
2
reading.
Repeated trimmer adjustments are
cumulative. Wait for a few minutes between
adjustments to allow the CO
2
reading to
stabilize.

Indicators
MI70 connection indicator
Shown on top left of the screen if an MI70
Indicator is connected to the service port.
Alert indicator and error text
Shown on bottom of screen if there is an error
active. Followed by an error text. If more than
one error is active, the error text will cycle
through the errors.
When the alert indicator and error text are
shown, typically one or more measurement
readings are replaced with stars. This means
these measurements are affected by the error.
