Hi, i have a Clipsal L5512RVFB and key input units in my apartment. I accidentally delete all my configuration in my 12 channel output unit. What I did was: 1) Entered Learn mode by pressing an output button for 10 secs 2) Double pressed an output button which selects all the 12 channels to turn on 3) Exit learn mode by pressing an output button for 2 secs. Now all my Key input units only shows a lighted up red LED whenever I press it but no lights are turned ON. What I tried but did not work: 1) Enter Learn Mode 2) Select the required output switches in the L55 unit which lights up my kitchen 3) Select an input button from my 4 gang wall switch input unit which shows the red LED lighting up 4) Exit learn mode by pressing the output unit for 2 secs. The kitchen light then turns OFF but the wall input switch still has its red LED lighting up. And this button doesn't light up the switch when i pressed it again. Any help would be greatly appreciated. I would prefer if I do not have to purchase a 5500 C-Bus PC interface. Thanks.
