HAS TO be from the same group).
• Connect a black wire to the output of the switch. Connect the other end of this black wire
to the input K of the LW12 MicroModule. See figure A.
• Place the module against the back of the wall box and replace the switch inside the box.
• Switch on mains fuse and master switch.
Programming the address and the optional functions All Lights On/All Lights
Off/All Units Off:
Unlike most Marmitek X-10 Modules the LW12 does not have code wheels.
When leaving the factory, the LW12 is set to the default address A1 en does not respond to
the optional functions All Lights On/All Lights Off/All Units Off. To change the address and the
settings for the All Lights On/All Lights Off/All Units Off functions, the module needs to be set
to the program mode.
Activating the program mode can be done in 2 ways:
1. By transmitting On / Off commands of the set address in quick succession (e.g. if the
address is B2: B2 ON, B2 OFF, B2 ON, etc.) After the LW12 has changed state 5 times, with
no more than 1.5 seconds between changes, the LW12 will no longer respond, which means
the module is set to the program mode.
2. By quickly pressing/switching the momentary switch connected to the module. After the
LW12 has changed state 5 times, with no more than 1.5 seconds between changes, the
LW12 will no longer respond, which means the module is set to the program mode. Once in
Program Mode the new address can be set by sending an "Address" or "Address On" (e.g.
B2 ON) or "Address Off" command for the new address code twice (using any Marmitek X-
10 controller). If you want to change the code again, just send the new ‘Address ON’ or
‘Address OFF’ commando twice. To set the unit to respond to "All Lights On" and/or "All
Lights Off" and/or "All Units Off" just send these commands twice for the new address code
(using any X-10 controller).
Please note: The "All Lights On/All Lights Off /All Units Off" options can be disabled by
setting a new address or by returning to the Default Setting.
Resetting the LW12
When leaving the factory, the LW12 is set to the default address A1 en does not respond to
the optional functions All Lights On/All Lights Off/All Units Off. If the address and settings for
the options "All lights on/All lights off /All Units Off" aren’t known, the default address of A1
can be set by applying power to the unit and sending the address P16 to the unit twice
(using any X-10 controller - i.e.: TM13 + RF remote control).
This can either be just the address "P16" or "P16 On" or "P16 Off". The commands must be
sent within 30 seconds of applying power to the unit. Setting the default address
automatically cancels the options "All Lights On", "All Lights Off" or "All Units Off".
