Optional features include a resistive temperature sensor output (with LCD display of temperature in either
°C or °F), a control relay with programmable setpoint, hysteresis and time delay, an up/down setpoint
control with various resistive output ranges and a dry-contact override switch.
BEFORE INSTALLATION
Read these instructions carefully before installing and commissioning the device. Failure to follow these
instructions may result in product damage. Do not use in an explosive or hazardous environment, with
failure of the product could result in personal injury. Take electrostatic discharge precautions during
installation. De-energize the power supply prior to installation, this device is intended for indoor air
conditioned spaces, contact factory or other applications. Do not exceed device ratings. This product is
not intended for life-safety applications.
NOTE:
This CO
sensor incorporates a Self Calibration feature to
2
correct CO
sensor drift. This feature is recommended for applications
2
where the CO
will be exposed to fresh air (400 ppm) at least one hour
2
per day. If the monitored space is occupied 24 hours or consistently
maintains higher or lower levels of CO
calibration is disabled at installation time without allowing for 7 day
auto calibration cycle, then a manual calibration should be performed
to ensure accuracy of the device.
MOUNTING
The transmitter installs directly on a standard electrical box and
controlled. Do not mount the sensor near doors, opening windows,
the detector is exposed to vibrations or rapid temperature changes.
Prevent measurement errors by sealing the wall or conduit openings
to prevent air migration from the wall cavity.
The cover is hooked to the base at the top edge and must be removed
the security screw as shown in Figure 1. Complete removal of the
screw is not required. Use the screwdriver to carefully pry each bottom
corner if necessary. Tip the cover away from the base and sit it aside as
shown in Figure 2.

INTRODUCTION
The room CO
transmitter device uses a highly accurate and reliable non-

room applications to monitor CO
and LTA (long term adjustment) signal processing technology to deliver
industry leading long-term accuracy and reliability. These technology
features ensure optimum measurement stability for both periodic and
constant occupancy applications, so the device is equally suitable for the
classroom or the hospital room.
mA, 0-5 Vdc or 0-10 Vdc for the highest versatility, programmable CO
