Description
The OE256-01 Wall Mounted CO
2
Sensor is
used in conjunction with the VCM-X Control-
ler (OE332-23-VCM) to monitor and control
CO
2
levels in the building environment.
Some typical applications are:

Demand Ventilation Control

Controlling ventilation in a building
where the occupancy varies frequently

Controlling ventilation based on CO
2
levels to ensure excess outside air is
not causing energy waste

To ensure good air distribution
throughout building zones
The OE256-01 is used for monitoring room
CO
2
levels and is designed for permanent
wall mounting in the conditioned space. It
connects to the VCM-X Controller by using a
modular prefabricated cable with RJ-45 con-
nectors. It can be daisy chained with the Ori-
on Modular Room Temperature Sensor or
Digital Room Temperature Sensor for appli-
cations requiring both a room CO
2
sensor
and room temperature sensor.
The OE256-01 CO
2
Sensor uses non-
dispersive infrared (NDIR) technology. The
CO
2
Sensor’s accuracy is
 50 ppm @1000
ppm or 2% of the measured value and has a
measurement range of 0-2000 ppm.
Mounting
The OE256-01 CO
2
Sensor utilizes a sub-
base mounting plate with either terminal blocks or modular phone jack providing for quick and easy mounting and
wiring. The wall-mounted sensor’s sub-base is compatible with standard junction boxes. A locking screw secures
the assembly to the wall.
