azbil TY6000Z2000 Neostat Room Humidistat

General

Neostat Models TY600_Z, TTY6023Z, and TY900_Z are a series of electric room thermostats. Neostat Model HY6000Z is an electric room humidistat. Neostat is similar in design and size to Neosensor, the electronic room temperature and/or humidity sensor. A temperature-sensitive diaphragm is adopted for the thermostat, and a moisture-sensitive nylon ribbon is adopted for the humidistat.

Features

• A simple connection to an actuator allows easy temperature/humidity control.
• Compact (thin) and lightweight.
• Several installation types were selectable in combination with optional auxiliary devices.

Dimensions

Neostat

Note:

• Secure more than 15 mm clearance inside the mounting wall when installing Neostat.

Adapter

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 per all applicable safety standards.

Requirements for installation location

IMPORTANT

• Installation location of Neostat largely affects temperature or 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.
• Hold the guide, but not the setting dial, when lifting the Neostat main unit. (See Fig. 3) Failure to do 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/temperature sensing is affected by draft, downdraft, and hot/cold air from water pipes/ducts.

• Humidity/temperature sensing is affected by weather conditions (including sunlight and outdoor air).

• There is vibration.

• Dew condensation occurs.

• Water drops on.

• Hot/chilled water pipe or steam pipe is located within 1 m radius.

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

• Chemicals or oils adhere.
  When they adhered, wipe them immediately with a dry soft cloth. If chemicals or oils remain on the case, chemical cracks might be made on it.

• Polluted environment that contains oil mist or other contaminants surrounds.

• Dust gathers on Neostat. (This may cause current leakage.)

• 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 a 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 setting dial, 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.
• Be sure to tighten all the screws necessary for installation.
• Tighten the screws with the specified torque (78.5 Nꞏcm for terminals and wall mounting screws, 39.2 Nꞏcm for main unit mounting screws). Neostat may get damaged by excessive tightening and may drop from the wall by insufficient tightening.
• Be careful not to touch the diaphragm or nylon ribbon when Neostat is uncovered.
• After installation, leave Neostat well so that it adapts to ambient conditions (atmospheric environment).

Wiring

CAUTION

• Installation and wiring must be performed by qualified personnel by 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 a short circuit.

Model TTY6023Z2000 adopts a lead wire connection and the rest of the models adopt a terminal connection.

Precautions for wiring

• Use M4 crimp terminals to connect wires to the Neostat screw terminals. (Tightening torque: 78.5 Nꞏcm)
• For connecting wires from the load, use 1.25 mm2 or greater stranded annealed copper wires with insulation.
• For splicing lead wires (from the load and from Neostat), use crimp sleeves with insulation.
• Correctly connect the wires from the load to Neostat.
• Make sure that all the wires are tightly connected.
