Thermostats AM1-WA1 and AM1-XA1
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.

Using a fan with a thermostat provides automatic on/off control of the fan and air flow switching.
ON/OFF Control of a Single Fan
●
When the temperature within the enclosure rises to a specified level
(preset temperature), the thermostat activates the fan automatically.
Once the enclosure interior is sufficiently cooled, it causes the fan to
stop. This is a great way to save energy and reduce noise.
◇
Application Example
ON/OFF Control of Multiple Fans
●
Multiple fans can be effectively controlled in cases where more than
one fan is needed to produce the required air flow or static pressure.
For example, a thermostat can control a maximum of nine MU1238
type fans. (A six-fan configuration is shown.)

Control the Number of Constant Speed Fans in Operation
●
The use of two thermostats enables switching the number of
fans being operated to change the air flow in accordance with
temperature.
This helps save energy and reduce noise.
This control method is effective with densely mounted equipment.

Notes:
Connect the lead wire to the thermostat as shown in the diagrams, regardless of how many fans are used or of the fan's wire diameter.
●
When connecting multiple fans, always use a terminal block. Don't connect the lead wires of multiple fans directly to the thermostat.
●
When using variable flow fan, don't connect the lead wires for connecting variable resistor directly to the thermostat.
●
Recommended Crimp Terminal
●
Crimp terminal is not included. When crimp terminal is required for connecting, use the crimp terminal shown below.
