The new LW12 Dimming Micro Module is the module everyone has dreamed of for years! This tiny module measuring only 40mm square by 15mm deep can be installed virtually anywhere, and best of all it does not require a Neutral connection, so is easily retro fitted behind an existing light switch (the switch would then need to be changed to a momentary action switch).

The unit also offers soft start, and dim, which means the light slowly fades up from off, when turned on, and slowly fades down to off, when turned off. Not only does this create a hi-tech feel to your lights, it also increases bulb life dramatically. The unit also remembers it's last dim level, so when next turned on, will return to that same level.

The module contains a special electronic fuse which opens if there is an over load, or the bulb blows, and then closes again when the fault goes away.

When the unit receives a message, it will operate as follows:
Off                              Light fades to off gradually
On                               Light fades on to memory level
Dim                              Dims from current light level
Bright                           Brightens from current light level
All Lights On                    Brings light 100% on immediately (no fade on)
All Units Off & All Lights Off   Full Off immediately (no fade off)

Wiring Changes for LW12

MicroModules require an X10 transmitter to set their internal address (they do not have Code wheels like the older modules). The cheapest CE Approved transmitter to do this is the MC10. Note that the CM12 is not able to set a MicroModules address
