Safety Precautions

Do not touch the terminals while power is being supplied. 
Doing so may occasionally result in minor injury due to 
electric shock.

Do not allow pieces of metal, wire clippings, or fine metallic 
shavings or filings from installation to enter the Product. 
Doing so may occasionally result in electric shock, fire, or 
malfunction.

Do not use the Product where subject to flammable or 
explosive gas. Otherwise, minor injury from explosion may 
occasionally occur.

Never disassemble, modify, or repair the Product or touch 
any of the internal parts. Minor electric shock, fire, or 
malfunction may occasionally occur.

If the output relays are used past their life expectancy, 
contact fusing or burning may occasionally occur. Always 
consider the application conditions and use the output 
relays within their rated load and electrical life expectancy. 
The life expectancy of output relays varies considerably 
with the output load and switching conditions.

Tighten the terminal screws to between 0.74 and 0.90 N·m. 
Loose screws may occasionally result in fire.

Set the parameters and wiring of the Product so that they 
are suitable for the system being controlled. Unexpected 
operation may occasionally result in property damage or 
accidents.

A malfunction in the Product may occasionally make 
control operations impossible or prevent alarm outputs, 
resulting in property damage. To maintain safety in the 
event of malfunction of the Product, take appropriate safety 
measures, such as installing a monitoring device on a 
separate line.

Be sure to observe the following precautions to prevent failure to 
operate, malfunction, or adverse effects on the performance and 
functions of the Thermostat. Not doing so may occasionally result in 
unexpected events.

1.

The Product is designed for indoor use only.

Do not use the Product outdoors or in any of the following 

locations.

Locations directly subject to heat radiated from heating 
equipment

Locations subject to water or oil

Locations subject to direct sunlight

Locations subject to dust or corrosive gas (in particular, sulfide 
gas and ammonia gas)

Locations subject to sudden or extreme temperature changes 

Locations subject to icing or condensation

Locations subject to vibration or shock

2.

Use and store the Product within the rated temperature and 

humidity ranges. Provide forced cooling if required.

3.

To allow heat to escape, do not block the area around the 

Product.

4.

Be sure to wire the Product properly with the correct terminal 

polarity.

5.

Use the specified size of crimped terminals for wiring (M3.5, width 

of 6.8 mm or less). To connect bare wires to the terminals, use 

copper wires with a gauge of AWG24 to AWG14 (equal to a 
cross-sectional area of 0.205 to 2.081 mm

2

). (The stripping length 

is 5 to 6 mm.) Do not connect more than two wires or two crimp 

terminals to one terminal. When connecting two wires, they must 

be of the same size and type.

6.

Do not connect anything to terminals that are not used.

7.

Allow as much space as possible between the Thermostat and 

devices that generate powerful high frequencies or surges. 

Separate the wiring to the Thermostat from high-voltage or high-

current lines, and do not place the wiring to the Thermostat in 

parallel with or in the same wiring paths as power lines.

8.

Use this Product within the rated load and power supply 

specifications.

9.

Turn ON the power supply at least 30 minutes prior to starting 

control operations.

10.

A switch or circuit breaker must be provided close to the 

Thermostat. The switch or circuit breaker must be within easy 

reach of the operator, and must be marked as a disconnecting 

means for the Thermostat.

11.

Do not use paint thinner or similar solvents to clean the 

Thermostat. Use standard grade alcohol.

12.

Design the system (e.g., the control panel) considering the 2.5 

second of delay between turning ON the Thermostat and 

stabilization of the Thermostat's output.

 CAUTION
