automatically performs ON/OFF fan control in
accordance with the temperature fluctuation inside
the equipment. It helps improve the equipment’s
“environmental” performance relative to energy
savings, noise reduction, etc.

Features
■
Effective for Energy-Saving
●
Thermostat makes it possible for fans to operate only when cooling
is necessary.
This product makes for energy-saving by automatically stopping fans
for example, at night, when the amount of heat generation declines
following the load rate’s decline in equipment, or in winter, when the
ambient temperature drops and forced cooling is not necessary.
Noise Reduction
●
The fans are operated only when cooling is required, thereby keeping
fan noise to a minimum.
●
RoHS-Compliant
Thermostats
AM1-WA1
and
AM1-XA1
conform to the RoHS
Directive that prohibits the use of six chemical substances including
lead and cadmium.

In addition, the setting is very easy; all you have to do is set the front
dial to the desired temperature.
Elimination of Power Supply
●
There is no need to provide a separate power supply for the
thermostat.

Notes:
If foreign objects get into the sensor, the thermostat may not work properly. The use of a filter
●
at the intake is recommended so foreign objects will not enter the area where the sensor is
located.
Be sure to use the applicable products.
●
Install the product on an IEC (DIN) rail. Make sure that no force (tension, stress, etc.) is
●
applied to the terminal section.
