    Rated 5 out of 5 by from 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.

    Rated 4 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 3 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Rated 5 out of 5 by from 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.

    Can the 57W be used to vary the speed of a Broan QT90E bathroom fan?

    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?
    Asked by: Rick
    It is recommened to use the 78w/78V. Others may cause a motor humming noise. If neededTechnical service # is 1-800-637-1453.

    Can the 57W be wired in series with a normal light switch?

    Asked by: quidproquo
    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.

    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 ?
    Asked by: Flash
    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

    Fit into a 3-gang box?

    Is it possible to fit the 57W into a 3 gang box with 2 other switches? Thanks.
    Asked by: Lonepine
    Thank you for your question on the model 57W solid state speed control. You can place the 57W in a three gang box with two other Decora style switches and cover it with a three gang Decora switch plate.
