Effective Use of the Thermostat
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.

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.)
