Reply to "Z-1000 with Z-Controller and CW-80 Waveforms"

Yes, I have seen that drawing before; never saw a triac drawn like that.

I have one CW-80 left, maybe I'll pull it apart later in the week just to see if there is anything to be learned. Who knows, maybe that ringing is from the fan motor! It is noticeably asymmetrical, as is the fan motor voltage/current due to the half-wave rectifier.
