This Class (A) digital apparatus meets all the
requirements of the Canadian Interference-Causing
Equipment Regulations.
Cet appareil numérique de la Classe (A) respecte toutes
les exigences du Règlement sur le matériel brouilleur du
Canada.
Installation
IMPORTANT: The CD-W00-x0-2 Series Wall Mount CO2
and Temperature Transmitters are intended to provide
an input to equipment under normal operating conditions.
Where failure or malfunction of the transmitter could lead
to personal injury or property damage to the controlled
equipment or other property, additional precautions must
be designed into the control system. Incorporate and
maintain other devices, such as supervisory or alarm
systems or safety or limit controls, intended to warn of or
protect against failure or malfunction of the transmitter.
IMPORTANT : Le CD-W00-x0-2 Series Wall Mount CO
and Temperature Transmitters est destiné à transmettre
des données entrantes à un équipement dans des
conditions normales de fonctionnement. Lorsqu'une
défaillance ou un dysfonctionnement du CD-W00-x0-2
Series Wall Mount CO2 Transmitters risque de provoquer
des blessures ou d'endommager l'équipement contrôlé ou
un autre équipement, la conception du système de
contrôle doit intégrer des dispositifs de protection
supplémentaires. Veiller dans ce cas à intégrer de façon
permanente d'autres dispositifs, tels que des systèmes de
supervision ou d'alarme, ou des dispositifs de sécurité ou
de limitation, ayant une fonction d'avertissement ou de
protection en cas de défaillance ou de dysfonctionnement

Do not apply power to the system before
checking all wiring connections. Short circuited
or improperly connected wires may result in
permanent damage to the equipment.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas mettre le système sous tension avant
d'avoir vérifié tous les raccords de câblage. Des
fils formant un court-circuit ou connectés de
façon incorrecte risquent d'endommager
irrémédiablement l'équipement.
CAUTION: Risk of Property Damage.
Do not run low voltage cable in the same conduit
or wiring troughs with high voltage wires.
Running low and high voltage wires in the same
conduit or wiring troughs may damage the
equipment or cause system malfunction.
MISE EN GARDE : Risque de dégâts
matériels.
Ne pas faire courir un câble basse tension dans
les mêmes gaines ou goulottes électriques que
des câbles haute tension. L'installation de fils
basse tension et haute tension dans les mêmes
gaines ou goulottes électriques risque
d'endommager l'équipement ou de provoquer
des dysfonctionnements du système.
IMPORTANT: Use copper conductors only. Make all
wiring in accordance with local, national, and regional
regulations. Do not exceed the CD-W00-x0-2 Series Wall
Mount CO
ratings. Exceeding transmitter electrical ratings can result
in permanent damage to the transmitter and void any
warranty.
IMPORTANT: When using multi-stranded wire cable,
apply a cable ferrule to the cable end. If the distance
between the sensor and the controller is over 3 meters
(9.8 feet), use shielded cable. Connect the shield at the
controller end of the cable.

Location Selection
When mounting wall model transmitters:
• Select a location that well represents 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.
Installing the Mounting Base and Cable
1. Open the transmitter by pulling outward on the
paper tab that holds the cover and mounting base
together (Figure 2).
2. Pull the mounting base away from the cover,
starting from the top.
3. Pull out approximately 6 in. (152 mm) of wire from
the wall and insert the wire through the hole in the
mounting base.
Note: Route the cable through the hole in the
mounting base if possible. You can also bring the cable
to the housing from above or below, but you have to
break off the small plastic tab that covers the hole on
top or bottom of the mounting base.
Note: Do not route the cable through the area marked
NO CABLES on the mounting base (Figure 3). That
space is taken up by the CO
when the cover is attached.
4. Align the mounting base on the wall, and confirm
that the arrow imprinted on the mounting base is
pointing up (Figure 3).
IMPORTANT: Proper orientation is important. Air
must flow through the vents on the bottom and the
top.
5. Secure the mounting base to the wall, using at
least two field-supplied screws (Figure 3).

the cable opening. If left unsealed, the hole allows air
from outside the room into the transmitter and affects
the measurement readings. For example, fresh
concrete binds CO
and may cause low readings,

especially in new buildings.
Connecting the Cable to the Mounting Base
Connect the wires from the cable to the screw
terminals on the mounting base. The terminal
assignments are marked next to the screw terminals.
Maximum wire size is 2 mm
2
(AWG 14).
Note: The transmitter is capable of generating both
voltage and current output. Each output has its own
individual positive screw terminal.
Power Supply Requirements
The transmitter requires a 24 VAC/VDC, Class 2 power
supply. Although the power input includes a halfwave
rectifier, we recommend using a DC supply to avoid
excessive current peaks.
Connections to a 24 VAC Power Supply
Connecting more than one transmitter to a single
24 VAC transformer forms a common loop and
increases the risk of a short circuit. We recommend
that you use a separate floating supply for each
transmitter (see Figure 5).

1. Strip 1/4 in. (6.35 mm) of insulation from the ends
of the power and output signal wires.
Note: To prevent a short circuit from occurring, make
sure that the wires are stripped to the correct length
and fully inserted into the terminal blocks. If using
shielded cable, ensure that the shield is protected from
contact with components on the top or bottom side of
the printed circuit board. Failure to follow proper wiring
procedures may cause the transmitter to fail.
2. Connect the wires to the mounting base screw
terminals as shown in Figure 4.

If several transmitters share a common transformer,
always connect the transmitter common (-) to the same
side of the transformer to maintain the polarity. A
shared common line at the controller may cause a
short circuit if the phase is not the same (Figure 6).
