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 Neostat largely affects humidity control. Carefully select the location.

●Ask our salesperson for use of Neostat in a special application, as mentioned below.

- 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 Neostat, shorten the service life of Neostat, or damage Neostat.

●Do not tighten or loosen the screws (except the screws described in the Installation steps sections). Doing so

might damage Neostat.

Install Neostat on an indoor wall where:

●Representative temperature/humidity (of the room/zone to control) can be measured (approx. 1.5 m high above the floor)).

●Ambient wind velocity is 0.1 to 0.15 m/s.

●There is enough maintenance space left in front of Neostat.

Do not install Neostat 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).

●Humidity sensing is affected by draft, downdraft, and hot/cold air from water pipes/ducts.

●Humidity sensing is affected by weather conditions (including sunlight and outdoor air).

●There is vibration.

●Dew condensation occurs.

●Water drops on.

●Atmosphere that contains corrosive gas, organic solvent, or other chemicals surrounds.

Do not install Neostat outdoors or in a duct.

Do not install Neostat directly or horizontally on a ceiling.

Precautions for installation

●Secure the clearance for wiring inside the wall (as shown in Figs. 1 and 3).

●Install Neostat with the optional dedicated mounting kit (sold separately) suitable for your application.

●Do not allow any refuse such as an electric wire scrap to get inside Neostat.

●Do not allow the lead wires caught between the mounting surface of Neostat and the wall.

●Do not put heavy load on the heat sink, the lead wires, etc. Doing so may distort Neostat, causing failure or affecting

humidity control.

●If air infiltrates to the rear side of the Neostat from the inside of the installed wall through the outlet box, shut off the air by

sealing the outlet box.

●After installation, leave Neostat well so that it adapts to ambient conditions (atmospheric environment).

Protection from radiation and conduction heat

To protect the measuring accuracy from disturbances

(including radiation and conduction heat) caused by the wall

where Neostat is mounted, the distance between the Neostat

sensing element and the wall can be changed by extending

the depth of the Neostat main unit. See the following steps to

change the depth.

1) Remove four mounting screws of Neostat.

Figure 13. Depth change: Removing the mounting screws

2) Raise the Neostat main unit from the Wall-direct

mounting kit. 9 mm max. can be raised.

Figure 14. Depth change: Raising the Neostat main unit

3) Set the depth change levers, located on the upper right

and left of the Neostat main unit, at the lower position.

(The levers are factory-set at the upper position.)

Figure 15. Depth change: Setting the depth change lever

4) Fix the raised Neostat main unit to the Wall-direct

mounting kit with four mounting screws.

Figure 16. Depth change: Fixing the raised main unit

5) Check that the depth of the Neostat is extended. Follow

the same steps to extend the depth of Neostat installed

on Thermoplate.

CAUTION

Installation and wiring must be performed by qualified personnel in accordance with all applicable safety standards.

All wiring must comply with applicable codes and ordinances.

Before wiring, be sure to turn off the power to the product.

Failure to do so might cause electric shock.

To connect the wires to the screw terminals, use crimp terminal lugs with insulation.

Failure to do so might cause fire or device failure due to short circuit.

Model HY9000Z is a proportional humidistat capable of performing proportional control of Control Motor (Model MY3000),

ACTIVAL (Model VY512_/VY522_/MY532_), or Modutrol Motor (Model M904E/M9184F1026/M9185A1075) that actuates

valve/damper.

IMPORTANT:

To connect Neostat (Model HY9000Z) to a product not specified above, ask our salesperson.

Internal connection

Figure 18. Internal connection diagram

Precautions for wiring

●For connecting wires from the load, .use 1.25 mm2or greater stranded annealed copper wires with insulation.

●Correctly connect the wires from the load and from Neostat, and make sure that all the wires are tightly connected.

●Refer to the figure above (the internal connection diagram) and connect the lead wires of Neostat to the wires from the load
