Installation
CAUTION
Use the product under the operating conditions (temperature, humidity, power, vibration, shock, mounting direction,
atmospheric condition, etc.) as listed in the specifications.
Failure to do so might cause fire or device failure.
Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.
Requirements for installation location
IMPORTANT:
●Installation location of Neosensor largely affects temperature/humidity control. Carefully select the location.
●Chemical (organic solvent) atmosphere may shift the output values.
●Corrosive gas, organic solvent, and other chemicals contained in the atmosphere can cause measuring error
of Neosensor, shorten the service life of Neosensor, or damage Neosensor.
Ask our salesperson for use of Neosensor in a special application, as mentioned above.
Install Neosensor on an indoor wall where:
●Representative temperature and humidity (of the room/zone to control) are measured (approx. 1.5 m high above the floor).
●Ambient air velocity is 0.1 to 0.15 m/s.
●There is enough maintenance space left in front of Neosensor.
Do not install Neosensor on a wall where:
●Heat (generated by office device or equipment, for example) stays on.
●Air circulation is interfered (by furniture or door, for example).
●Temperature and/or humidity sensing is affected by draft, downdraft, and hot/cold air from water pipes/ducts.
●Temperature and/or humidity sensing is affected by weather conditions (including sunlight and outdoor air).
●There is vibration.
●Dew condensation occurs.
●Water drops.
●Corrosive gas, organic solvent, or other chemicals is contained in the atmosphere.
Do not install Neosensor outdoors or in a duct.
Do not horizontally install Neosensor directly on a ceiling surface.
Precautions for installation
●Install Neosensor with a dedicated mounting kit (sold separately) suitable for your application.
●Do not allow any refuse such as an electric wire scrap to get inside Neosensor.
●Do not get a cable caught between the Neosensor main unit and the mounting surface.
●Carefully handle Neosensor when the cover is removed so that the element does not get damaged.
●Check that the ambient air velocity is sufficient in a location (not on a ceiling surface) where Neosensor will be horizontally
installed.
●If air infiltrates to the rear side of the Neosensor from the inside of the installed wall through the outlet box, shut off the air by
sealing the outlet box.
●After installation, leave Neosensor well so that it adapts to ambient conditions (atmospheric environment).

Cover removal
Do not bend the humidity sensing element attached to the PCB board assembly. Otherwise, measuring accuracy may drop.
To remove the cover:
Press the spring, located inside the top of the Neosensor
main unit, using a thin object.
To attach the cover:
Engage the tabs located on the lower part of the cover with
the slots on the lower part of the main unit. Then fix the
cover with the spring, located on the top of the Neosensor
main unit.
Protection form heat radiation and conduction
To protect the measuring accuracy from disturbances (including heat radiation and conduction) caused by the mounting surface
where Neosensor is mounted, the distance between the Neosensor sensing element and the mounting surface (depth of the
Neosensor main unit) can be changed. See the following steps to change the depth.
1) Remove four mounting screws of Neosensor.
Figure 15. Depth change: removing the mounting screws
2) Raise the Neosensor main unit from the Wall-direct
mounting kit. 9 mm max. can be raised.
Figure 16. Depth change: Raising the Neosensor main unit
3) Set the depth change levers, located on the bilateral
sides on the main unit front surface, at the lower position.
(The levers are factory-set at the upper position.)

Precautions for wiring
IMPORTANT:
•Do not connect the lead wires for temperature output to the power supply line to prevent smoking or burnout.
Make sure all the wires are correctly connected before supplying power.
•Single Neosensor must be powered by a single 24 V AC transformer. Do not connect the transformer to any
other device in addition to Neosensor.
●For power supply wiring and temperature/humidity output wiring, 1.25 mm2or greater shielded multi-core cables (JIS
CVV-S) are recommended. 1.25 mm2or greater JIS IV cable is also connectable. Be sure to ground the shielding on the
controller side.
The maximum cable length is 100 m.
●Because the temperature sensor model with RTD (Pt1000) output is two-wire, the wire resistance will cause measuring
error. For instance, 1.25 mm2size wire causes approx. 0.1 °C measuring error every 10 m. Correct the measuring error by
setting the controller in connection.
Transformer for Neosensor (humidity sensor, temperature/humidity sensor models)
IMPORTANT:
Use isolated transformer to supply 24 V AC power.
Single Neosensor must be powered by a single 24 V AC transformer. If the multiple Neosensor or a
Neosensor and a device in connection are powered by a single 24 V AC transformer, the common wiring will
form a loop, and Neosensor will get damaged.
24 V AC transformer: Two Neosensor powered by a single transformer
Figure 22. Bad wiring examples: Two Neosensor (temperature/humidity sensors) powered by a single 24 V AC transformer
24 V AC transformer: Two Neosensor separately powered by two transformers
Figure 23. Good wiring example: Two Neosensor (temperature/humidity sensors) powered by separate 24 V AC transformers
If the transformer is misconnected, it will short-circuit through the common wiring.

24 V DC transformer: Multiple Neosensor powered by a single transformer (correct example)
Multiple Neosensor or a Neosensor and another device in connection can be powered by a single 24 V DC power.
Figure 24. Good wiring example: Two Neosensor (temperature/humidity sensors) powered by a single 24 V DC transformer
Notes for signal wiring
Induction current flowing from Neosensor (humidity sensor, temperature/humidity sensor models) to the controller input circuit
and inadequate time constant of the controller might generate noise. To prevent noise, see the following.
•Use a controller with low pass filter (40 dB or higher removal ratio in normal mode) that receives signals from Neosensor.
•For insufficient removal ratio, provide an isolator on the controller input wiring.
Note:
No problem will occur for connecting Neosensor to our controller.
IMPORTANT:
•When Neosensor is faulty, reduced output may cause over-humidification. Provide safety measure against
over-humidification.
•Corrosive gas or organic solvent contained in the air may cause sensing error, shorten the service life, or
damage the Neosensor. Before using Neosensor in abnormal atmosphere, consult with our salesperson.
Though common wiring forms a loop, common mode noise affects a little.

Inspection and Maintenance
Since Neosensor is factory-inspected and -calibrated for high accuracy, no field calibration is necessary when Neosensor is
installed. For inspection and maintenance, follow the instructions below.
Periodic inspection
Periodically inspect Neosensor for its measuring accuracy, and clean the cover. Set the period between inspections based on
how much atmospheric dust and other contaminants are contained in the installation environment.
If Neosensor is installed in an animal holding room or a hospital operating room, cover Neosensor when the room is sterilized.
Troubleshoot
If any problem occurs during operation, refer to the table below for appropriate solutions.

Calibration
Neosensor is factory-calibrated and does not require field calibration right after installation. However, field-calibrate Neosensor
if a shift in the output due to aged deterioration is found.
For a humidity output error, calibrate the Neosensor with adjustment knobs on the board inside the main unit. Follow the below
instructions for calibration.
●Two adjustment knobs (VR1 for fine adjustment and VR2 for rough adjustment) are provided.
Turn clockwise to increase the output value and counterclockwise to decrease the output value.
Note that the measuring accuracy specified hereinbefore will not be assured after field-calibration with the adjustment
knobs.
●Carefully field-calibrate Neosensor so that the heat on your hands do not affect the Neosensor.
Do not allow the heat generated from human body and/or appliances to affect Neosensor while calibrating.
●Use a reliable calibration instrument for field calibration.
●Carefully handle the product and check the appropriate environment for field-calibration.
●Calibrated digital multimeter is recommended to check output value.
Notes:
* Temperature output cannot be calibrated.
* Ask our salesperson if a shift in the output of new Neosensor is found.
