That's a good question, and I really don't know the answer. Every
universal I've seen, that use dip switches, including the Casablanca
w-52, have four switches just like your transmitter. Last summer I
installed a fan with remote control that used a "learn" button, similar
to those on garage door operators.
Hmmm.... that's interesting. Thanks for the detail.
I suspect mine are all *old* fans, probably at least dating back to the
90's for the original fans, and then dating maybe to the 2000s for the
two newer fans (in the remodeled part of the house).
So, for now, I'll "assume" that the 4-position DIP switch will run them
all if I can just verify that they have 120V going to them.
I haven't been able to work on them today - but hopefully tomorrow I'll
have more detail.
