<br /> The LW12 can be controlled with X10 signals via the mains or a momentary switch connected to the LW12. The LW12 has a memory setting for the last dimmer setting and uses SoftStart and SoftDim. The LW12 is the only X10 module that doesn't use a zero wire. This means it can replace a switch without having to use any extra wiring.<br /><br /> The AW 12 reacts to the standard X10 commands that are: "All Units On", "All Units Off", "All Lights Off" from any X-10 controller set to its house code regardless of unit code or alternatively individual unit control by "On" an "Off" commands.<br /><br /> House code and unit code are programmed using any X10 compatible controllers. There is an EEPROM that stores the house and unit code even when the power is cut.">
