This CO2 2 sensor optimizes the amount of airow in accordance with the CO concentration within the room, and thus reduces the
fresh air load.
Refer to the specication sheet for applicable Lossnay models.
■ This manual must be read both fully and carefully before commencing installation procedures; furthermore, the subsequent
installation must be performed correctly and safely in accordance with the instructions given.
■ After installation, ensure that this manual is given to the customer.

If it is installed improperly, electric shock, re, etc. could result.
- Close the control cover after installation.
-Donotinstalltheproductinaplacewhereammablegasesmayleak.
If gas should leak or accumulate around the product, re or explosion could result.
- Do not use the product in special environments.
The product could be damaged if it is used in locations subject to large quantities of oil (including machine oil), steam, or sulde gas.
-Donotinstalltheunitinaplacewherethetemperaturerisesabove40˚C(104°F),wherelargeamountsofoil,steam,

used frequently.
These substances can compromise the performance of the unit or cause certain components of the unit to corrode, which can
result in electric shock, malfunctions, smoke, or re.
CAUTION Incorrect handling could cause injury or damage to property or household e󰀨ects.
- Wire so that it does not receive any tension.
Tension could cause wire breakage, heating or re.

Power consumption 2 W or less.
Usage environment 0 ˚C to 40 ˚C (32 ˚F to 104 ˚F),

Detection range 400 to 2000 ppm
* 1: In the range of 0 ˚C (32 ˚F) or less, CO2 Sensor may not
detect the correct CO Concentration.2
* 2: The sensor measures CO2 concentration of the air owing
the duct. It may be di󰀨erent from the value at hand. In
addition, the measurement accuracy may vary depending
on the usage environment, installation conditions, etc. but
this is not a malfunction.
3. Installation Method
* Refer to the Operation Instructions and Installation
instructions of Lossnay unit.
RVX3 series. Depending on the model of Lossnay or instal-
lation condition, the actual PCB and following diagram can
be upside down.
3.1 Before installation
Be sure to perform installation while the power of the Lossnay unit is O󰀨.
Remove the Lossnay unit control box cover.

(2) Fix CO2 sensor on the duct.
Forroundduct
Forrectangularduct
In case of installing on the rectangular duct like RVXT series,
place the sensor on the center of whichever side except bot-
tom side.
Also the minimum distance between the sensor and Lossnay
inlet shall be 300 mm or more for normal detection.
Note:
- When the sensor is installed on the duct above non-CO2
detachable ceiling, make sure to x a opening for servicing.
- Choose screws with corrosion resistance so that rust does
not occur due to potential di󰀨erence between the duct and
screws.
- The location where sensor is mounted should be noted and
- Do not install the sensor just before or after bends, expan-
sion or reduction. It could cause incorrect concentration CO2
detection.
- Installing sensor in the wrong position may prevent cor-CO2
rect operation. Furthermore, this may result in damage to the
sensor, or a shortened service life.
- Do not use an electric screwdriver.
- Do not disassemble the sensor (sensor section) resin CO2
case.

(3) Follow the steps below to shift the ferrite core on the cable
220 mm from its original position to the sensor unit side.
- Remove the ferrite core, align the lead mark with the left
(connector side) end of the ferrite core, and wrap it once
to close the ferrite core.(Align the claws of the ferrite core
and attach until it clicks.)
(4) Pass the CO2 sensor cable through the cord clip and pass
them through either bushing. Collect excess cable by using
the cord clip mounted in the side of the control cover.
Note:
- Be careful not to exert force on the sensor.CO2
- Seal the opening between the busing and the cables in order
not to intrude insects.
