Installation
Location
1. Locate the Neostat about 1.5 m (5 ft.) above the floor
where average temperature and humidity of the space
can be measured.
2. Avoid “dead spots” such as behind large pieces of
furniture or doors without good air circulation.
3. Do not mount the Neostat where it may be affected by
drafts, hot or cold air from ducts, radiant heat from the
sun or appliances.
4. Do not mount the Neostat where it may be affected by
vibration.
5. Do not mount the humidity controller where it may be
affected by water drop. Do not allow dew
condensation to form on the unit.

Mounting Procedure of Baseplate (See Fig. 3)
1. Install box cover with pitch of 66.7 mm (Box cover JIS
C 8339) on the outlet box when needed.
2. Put mounting plate (order separately) on the box
cover.
3. Then put baseplate (order separately) on the
mounting plate.
4. Wire the baseplate. Refer to wiring section.
5. Remove the cover. (See Fig. 5) Then, mount the
Neostat on the baseplate. See Fig. 6 also.
6. Replace the cover.
Fig.3 Mounting baseplate
Mounting Procedure of Thermo plate (See Fig. 4)
1. Mount the Thermo plate. Refer to the instruction of
Thermo plate.
2. Mount the terminal block on the baseplate.
3. Wire the terminal block. Refer to wiring section.
4. Remove the cover. (See Fig. 5) Then, put the Neostat
on the baseplate (See Fig. 6) and mount to the
terminal block.
5. Replace the cover.

Wiring
All wiring must comply with local electrical codes and
ordinance. In general these codes require:
1. Wire no smaller than #14 (1.6 mm).
2. All terminal connections should be carefully made. In
making surface wiring, use knockout on the top of the
body where marked.
3. Make correct wiring. Check the screw terminals for
loose connections.

Setting
1. Remove the cover.
2. T6065B and T9065B have S/W changeover switch.
Set the lever in the specified position. See Fig. 10.
Note: When the equipment is energized, do not
change the switch.
3. The temperature controller have setpoint stoppers
(Fig. 8) and the humidity controller have a setpoint
lock screw (Fig. 9). The Neostat is shipped from the
factory with setpoint dial locked in the position as
follows:
Temperature controller→30 °C
Humidity controller 30 to 80 % RH model→80 % RH
50 to 90 % RH model→90 % RH
After sliding the stoppers of the temperature controller
or after loosening the lock screw of the humidity
controler, adjust the setpoint dial to the desired
temperature or humidity. Setpoint is the center of
throttling range for proportional controllers. For two-
position controllers, see Figs. 11 and 12.
4. Set the setpoint stoppers or a lock screw as occasion
calls.
5. Replace the cover.
