Dimmable Vertical Fan
« on: March 17, 2014, 01:29:38 am »
I was looking to add a fan to my bedroom.  I have an existing unit but it makes weird noises when I dim the Z-Wave module (Aeotec Smart Switch).  Also, the fan stays off after the power is cut...so I would need an IR blaster to turn it on.

Instead of an IR blaster, I was thinking of using a cheaper, hard switch (no fancy electronics), vertical fan that can be dimmed.

Are the weird humming noises when I dim the electronic...or can you not dim a fan?

Sorry if this is a basic electrical question. I thought it would work with my existing fan.

Most fans use induction motors which cannot be dimmed.

Thanks Rex, using your search terms, I found out more details on why this is a bad idea.

Well, if someone made a low-cost Z-wave compatible variable frequency drive...  ;)

Would this work?

The original switch was a 4 position (three speeds and off) switch?  This is meant to replace that type of switch.

There may be wiring in the wall for it if you originally has a single pole switch and were using the chain to set the speed.

so the answer is: "it depends" as so many home automation questions tend to get answered.

If you have a light circuit tied to an outlet that you could replace a traditional switch with, then yes I guess so. Otherwise stick it in a closed dual gang enclosure with a 120v cord and outlet, and hey-presto same thing really :)

Once you mount the fan controler in there, just need to then add an outlet, a dual gang decora face-plate, and way to secure a cord through the side, for which there are few options.
