I just received this information from Emerson's technical support group,
and as it's undocumented (anywhere I was able to find it, anyway!) and
extremely useful, I thought I'd throw it out on the bitstream. If you
find this in a search a few years from now and it solves this pesky
Most Emerson ceiling fans need a matched controller/receiver, the SW375,
to function. These receivers are matched to either the wireless SW330
control or the wall-mounted SW350 control (which appear to work
identically via RF signals, incidentally!) by "code learning" the desired
control to the desired fan.
If you only have one fan/receiver/control set, you're unlikely to ever
encounter the problem of one remote controlling multiple fans. However, I
have three, and for various reasons have switched around the receivers
and controls, and ran into the annoying problem of a remote in one part
of the house controlling more than one fan - even a fan quite some
If there is any information about "un-code-learning" or erasing the
memory in the SW375, so that a particular remote will no longer actuate
it, it's not recorded anywhere - including in the large and comprehensive
installation and use manual that comes with each Emerson component.
The solution turns out to be extremely simple, and revolves around this
fact: each receiver can store up to four remote codes. The remotes issue
control codes something like Genie's Intellicode, where a rolling code is
generated each time the learning button is pressed. (That might not be
completely correct, but it's the gist of it and functionally correct!)
So: If you have receiver A and have matched it to remote A, and then
install another fan (B) and accidentally code remote A or B to the wrong
fan, you'll get overlapping control. The fix is this: overwrite all four
codes in the receiver with the correct remote. This will push out codes
from any other remote and leave the receiver and fan operating ONLY with
the correct one.
1) Turn off all Emerson fans at the wall switch or circuit breaker.
2) Turn on power to the fan you want to program or reprogram. The
receiver will beep.
3) IMMEDIATELY press the code-learn button. Each time a code is learned
by the receiver, it will give a double beep. DON'T release the code-learn
button until the receiver has double-beeped at least four times.
Voila - that fan will no longer operate with any but the remote you just
used to program it.
On the SW350 wall controller, there is a specific code-learn button. On
the SW330 handheld controller, you press the SLEEP and SELECT buttons
simultaneously to send a code-learn. You have to send all code-learn
signals (from all the remotes you want to operate that fan, up to four)
within about two minutes of first powering up the receiver. Be absolutely
certain that all other fans are POWERED OFF or they might pick up the
code-learn too, starting the whole mess over again. Also, if you're going
to program multiple remotes to a controller, be sure to let only the
FIRST one beep four times (to clear any old codes), then do ONE code-
learn beep from each successive remote. Otherwise you'll clear out remote
codes you want to keep.
Hey, I was thrilled to learn this trick. Hope you are, too. Someday.

ronileduc had written this in response to
Thank you, thank you, thank you! The batteries died in my remote and after
changing them, I still couldn't get the remote to work.Had no clue how to
proceed, was about to go buy a new one. Really appreciate the time and $
you've saved me by telling me how to re-sync the controller and remote.
You've made my day, and again, thank you!!
