L4678 - LEGRAND 3440 Technical Sheet

Dimmer actuator 300VA
Description
The device is a dimmer for controlling resistive loads and ferromagnetic transformers. It
is used to turn on and off and adjust the brightness of the load. It can be controlled via
the BUS or the local button. Briefly pressing the button turns the load on or off, while
holding it down adjusts the brightness.
The actuator is able to signal any load faults such as, for example, lamp failure. It is also
protected by a fuse, easily replaceable should it blow.
The LED on the actuator changes colour depending on the status of the device:
- green/blue: power ON, load OFF
- red: load ON
- blinking: incorrect configuration

Configuration
If the device is installed in a My Home system it can be configured in two ways:
- PHYSICAL CONFIGURATION, inserting the configurators in their sockets marked on the
back of the device:
- Configuration via MYHOME_Suite software package, downloadable from
www.homesystems-legrandgroup.com; this mode has the advantage of offering many
more options than the physical configuration.
For a list of the procedures and their meanings, please refer to the instructions on this
sheet and to the "Glossary" section of the Guide to designing and installing My Home.
