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.)
