    Rated 5 out of 5 by GREAT CONTROL USED ONE OF THESE FOR EACH EXHAUST FAN I INSTALLED, WORK GREAT. April 6, 2015
    Rated 5 out of 5 by Smooth variable fan control It's made by Broan so you know it is quality made. Comes with everything but your choice of box to mount it in. I used this as a speed limiter on a floor fan that was ridiculously fast no matter which of the 3 speeds I put it on. I tapped this into the main power going to the fan and left the fan on High. Worked great. Just make sure the fan you hook it up to does not draw any more the the switches 3 amp rating. July 9, 2013
    Rated 4 out of 5 by Good Performance/Price This speed controller is more than a simple "dimmer/resistor" device. It operates well and allows the user to nicely contol the noise level of the small Broan exhaust fan. It probably has circuitry that controls the voltage to the motor. At first a concern was that when switched "on", the fan ran at high speed until the dial was turned fruther. However, that first high speed opens the fan damper blades and then it is slowed to the desired speed - a good feature. June 19, 2013
    Rated 5 out of 5 by Nice little unit I did a little research before I bought this unit and the reviews were positive so I went ahead and got one and it was easy to hookup and it works fine. It is a little loud when its on high. Works as advertised. December 13, 2012
    Rated 4 out of 5 by Good quality, control switch Works great with the exhaust fan June 7, 2012
    Rated 3 out of 5 by Check your application This switch is fine, but not for the Broan 12C, which has a motor operated outside door. When the power is reduced to the fan, the door closes, rendering the fan useless. We ended up installing a standard on/off switch. July 4, 2011
    Rated 5 out of 5 by Great Noise Solution We replaced our four bath fan switches with the variable speed switch. Installation was a snap, quality and appearance excellent and the noise factor was significantly improved. June 19, 2011
    Rated 5 out of 5 by Perfect design This variable speed control (the white version of the 57 control; 57V is ivory) looks and performs perfectly in every way. Notice that it requires a wallplate with a Decora hole; it comes with a 1-hole wallplate, but if you're installing it in the same box as one or more other switches or outlets, you'll need to get a multi-gang wallplate with a Decora hole for the 57, and of course with the matching color. This control works with any exhaust fan, but not with ceiling fans. October 30, 2010

    Do you provide voltage and frequency control for the fan or just voltage control via a triac? If triac control, how do you protect the fan motor from burning at low speeds or humming noise? Please give details.

    I have installed a Broan QT90E and the users complain it does too good a job of removing the hot air from the bathroom (it's 90CFM rating is a slightly higher than the calculated requirement). Can the 57W be used to vary the fan speed without damaging the QT90E?

    Can a 57W be wired on a timer

    Can the 57W fan speed control be wired to a timer (solid state) so the fan can be timed for (example) 5, 10, 15, 30 minutes - i.e., the speed contol wired the timer, the timer being the source of line supply for the 57W speed control ?

    Answer: 
    Thank you for your question on model 57W. There should be no reason that a speed control switch cannot be used in conjunction with a timer switch. The way this way this would be wired, would be to have these devices in series with one another. This way, the timer will run for the desired time, at the speed chosen with the 57W

    Answer: 
    Thank you for your question on model 57W. Yes. The 57W speed switch may be installed in series with a normal wall switch. When the switch is up, or in the on position, the fan will operate at the selected speed on the 57W.
