Installation
Installation requirements
1) Mount Neosensor on a wall approx. 1.5 m high above the floor, where the average temperature and humidity can be
measured.
2) Avoid locations where room air circulation is not interfered by furniture or a door, and where heat from office automation
equipment stays on.
3) Avoid locations affected by draft, downdraft, hot/cold air from pipes/ducts, and radiant heat from the sun.
∗
The ambient air velocity in the Neosensor installation area should be between 0.1 and 0.2 m/s.
4) Choose an installation location with no vibration.
5) Do not install Neosensor where water may drop.
6) Do not allow dew condensation on Neosensor.
7) Do not install Neosensor directly on the wall without Wall-direct mounting kit.
8) Note that the output values for Models HTY7043DXXXX, HY7043DXXXX and TY7043DXXXX (2-wire 4-20 mA output
type) may vary depending on Neosensor installation environments, including temperature, humidity and air velocity.
Please consult with Yamatake's service personnel in charge regarding the installation.
Installation procedure: Neosensor directly on a wall (See Fig. 4.)
1) Attach the mounting plate to the box cover (outlet box mounting dimension: 66.7 mm (JIS C8340:1999)) located inside
the wall.
2) Install the main part of the Wall-direct mounting kit on the mounting plate. (See Fig. 9.)
3) Connect the output lead wires of the Neosensor main unit to the external wires (for the load side). (See Figs. 15 and 16)
4) Remove the cover from the Neosensor main unit, and mount the main unit on the main part of the Wall-direct mounting
kit with the 4 main-unit accessory screws (M3
×
16). When mounting the main unit onto the Wall-direct mounting kit,
make sure to set the height-adjusting levers on the left and right sides (See Fig. 12.) to the upper positions (indicated by
"L").
5) Place the cover back on the Neosensor main unit to complete the installation procedure. (See Fig. 8.)
