I'm pretty sure we will automatically convert your circuit 2 channel 1 to our channel 17.
If you've setup you models and mapped them to channels and you have some channels defined in the Setup tab just start a new sequence, goto sequence settings, click data layers tab, click Import, make sure filetype is .lms, select your lms file, wait for channel number to populate, close dialog and wait for it to finish rendering. Then play the sequence and look at your house preview.
