Have had 2 of the #27187 series controls for years and have had very few issues until recently the module which goes into the base of the fan housing stopped working.
I purchased the 99110 series to replace the defective unit and it is a piece of junk.
I followed the installation directions to a "T" and after pairing the remote to the unit, it works only half the time. If the remote is mounted on the wall plate or sitting on the dresser top, it only work 20% of the time. You have to hold the remote and point directly at fan to get a response and then it is still random.
Definitely would stay away from this remote control system.
