Installation
Requirements for installation location
IMPORTANT:
Installation location of Neosensor largely affects temperature/humidity control. Carefully select the location.
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).
There is enough maintenance space left in front of Neosensor.
Environmental conditions including temperature, humidity, and wind velocity of installation location can affect output value
(sensing accuracy). Ask our salesperson for the use of the two-wire 4-20mA output 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.
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 the Neosensor when the cover is removed so that the element does not get damaged.
Check that the ambient wind velocity is sufficient in a location where Neosensor will be horizontally installed even not on a
ceiling.
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.
IMPORTANT:
Change in environmental conditions (wind velocity, temperature, humidity, power voltage, load resistance) will
cause an offset. After the offset is compensated, a further compensation may be required each time when
environmental conditions change.
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 a special application, as mentioned above.
