If you have chosen which remote controller keys will be used as controlling keys, we can start with memorizing process. Press and hold button until lights go 3 times to maximum. After that, light will turn OFF, and that is indication of successful entering “memorizing the remote controller keys” mode, then you can release button. In the next 5 seconds, you must press the first key on remote controller, if you do, lights will blink several times. After that, you must press the second remote controller key, if you do, lights will also blink several times. That’s all, memorizing process is finished. 

You can change the assigned remote controller keys when you wish. After powering down the Ir LightDimmer, it will keep in memory these remote controller keys, so you don’t have to memorizing remote controller keys again when the device powers up. 

You must be careful when you connect IrLightDimmer to electrical wire, so you must break fuse switches of your lights. All connections must be like in my schematic, otherwise device will definitive burn out.

If you have IrLightDimmer mounted and connected and you want to change your lights, you must break fuse switches because there is risk of electric shock.
