If I put in an XPDI3 instead of the XPS3 for the fan would it have the same problem? I'm assuming since it's a dimmer module with soft start it would start up slow to high and shut off the same way so it wouldn't click back on right? I just turn it on then down to the speed I want and it will remember it when I turn it off and back on like a WS12A does. Is this right? I know there is a possibility of fan hum with dimmers.
Perhaps someone will elaborate on the electrical dangers but an X10 dimmer and most, if not all standard dimmer switches, should
never be used for a fan. The fans are not designed to work on a variable voltage. Each speed setting of the fan switches to a specific wiring in the fan for the respective speed.
It is more than just a possible hum issue.
