The X-10 DIN rail dimmer (LD11) is a 700 W receiver module that serves as remote controlled dimmer.

Mounted on the DIN rail in the mains distribution box, it dims/switches hard -wired circuits with several wall switches (e.g. living room lighting).

It is designed to operate with 230 V and 12 V lighting including halogen.

The LD11 can be turned on/off, and brightened/dimmed either by an X-10 controller or by external momentary action switches connected to terminal 2 - maximum connected cable length is 30 metres.

The LD11 responds to "standard" X-10 that is: "All lights on" or "All units off" from any X-10 controller set to its house code regardless of unit code or alternatively individual unit control by "On", "Off", "Bright" and "Dim".

The LD11 also responds to "professional X-10". Combined with the memory dim feature, the LD11 can change the room lighting instantly or progressively.

This unit is especially designed for scene lighting where very often the lighting is 12 V halogen, commonly used in living room, study/reading rooms. The unit can be installed in sub-junction boxes for discrete control.

This unit is especially designed for scene lighting where very often the lighting is 12 V halogen, commonly used in living room, study/reading rooms and Kitchens. In such instances ensure that a proper dimmable tranformer is used but do not use the 'torroidal' type. The unit can be installed in DIN-enclosures for discrete control. see [DIN-ENCLOSURES

Dimming the LD11 with Comfort: The X10 pre-set dim level for LD11 is used in the extended X10 command is put into effect when the X10 command is executed. Although you have set dim levels for each X10 address, when you execute them together, only the last one is used, because Comfort only has one memory for the level to be used. What you should do is to use a timer to delay each X10 command eg to Dim A1 to level 4, A2 to level 18, A3 to level 30 and A4 to level 48. Where 140 is the preset dim command, 195 is the X10 address. Resp X1: 140, 4,49, 195,65,1,15, 194,1,0,1,X2,255 Resp X2: 140,18,49, 195,65,2,15, 194,1,0,1,X3,255 Resp X3: 140,30,49, 195,65,3,15, 194,1,0,1,X4,255 Resp X4: 140,48,49, 195,65,4,15,255 etc You can use the same timer (timer 1 in this example) to run in sequence after a delay of 1 second (in the example) to do the sequence of responses. In this way, each X10 command will have its own dim level to use, as the previous command should have been completed. You may need to increase the delay if not enough.
