Duct Mounted CO
2
Sensor
The OE256-02 CO
2
Sensor is used for sensing the current CO
2
level
in the HVAC unit’s return air stream. This is useful when you want an
average CO
2
reading in the area served by the HVAC unit or when you
don’t want a wall mounted CO
2
sensor due to sensor tampering concerns
in the space.
The OE256-02 Duct Mounted Return Air CO
2
Sensor is comprised of the
OE256-01 CO
2
Sensor and the WattMaster Aspiration Box Assembly.
The Duct Mounted Return Air CO
2
Sensor is designed to be mounted in
the return air duct of the HVAC unit and uses its integral aspiration box
to sample the CO
2
level in the duct. See the dimensional and installa-
tion information in Figure 8 below for wiring and installation details.

Note:
1.) The CO Sensor Always Connects To The VCM-X E-BUS
Controller Using A TSDRSC Cable Of The Required Length.
If Also Using a Digital Room Sensor, Connect the Digital
Room Sensor to the C
Sensor Using Another TSDRSC
Cable Of The Required Length. The Total Length Of Cable
For All Sensor Cables Combined Cannot Exceed 160 Feet.
