Easy to install, works good, but would have preferred for lower rpm on low.

I'm a licensed engineer. I have an attic-style fan that I installed to circulate warm air from my utility room to the living spaces rather than letting that heat it escape through the attic by conduction. To accomplish this, I set the fan up with a thermostat control to turn on above 90F, which keeps the utility room pleasantly warm and dry while also re-circulating the excess heat. The problem was that the fan was way too fast and too loud in the adjacent living spaces when it kicked on. I needed something to slow down the fan, which was a low wattage AC fan with a permanent capacitor across the line (little round guy on the power cord going to the motor). You can't use a dimer switch for this sort of application because it will burn up, and many fan controllers intended for ceiling fans won't work either because they have fixed detents for replicating industry standard speeds at low/medium/high. By contrast, this controller uses a solid-state component called a Triac to give you much more precise continuous control over the fan speed. Using this controller, I was able to lower the fan to a much slower speed than the standardized fan controls, allowing me to get the right balance of comfortable warm airflow and quiet noise levels. When doing this, it is important to realize that AC motors can stall if the voltage is lowered too much, and that they will burn up in place if they stall with power on. These motors need the airflow to keep themselves cool while running. This control has a fine adjustment for setting for the minimum fan speed, which prevents someone from accidentally stalling the motor with the knob alone. This minimum speed adjustment was essential for me to achieve the desired effect in my home while preventing the fan from lowering below stall speed. Overall, this controller allowed me to fine-tune my attic-style fan safely and make my home much more comfortable in the winter while saving me money on heating bills and reducing the heat level in my utility room.

Worked great when others did not

I bought this for my exhaust fan in my food trailer. It fits good and seems very durable. It's easy to use and well worth the money.

Don't get suckered in as I did. There is no way to control the speed on an AC motor. The only way is to vary the frequency. This company is guilty of false advertisement. This is a cheap switch which is manufactured in Hong Kong. It does not do what it is supposed to be able to do. If you buy one and hook it up, it may ruin your motor, cause everything on the circuit you have it plugged into to draw down to nothing and possibly ruin all of those items as well. Needless to say===== I do not recommend it and wish I would not have wasted my money.

We bought this unit to control the fan on a gas fireplace we installed in our basement as we finished it. We wanted to be able to control the fan more than just on/off and loved the retro look on this. I'm not an electrician, but I have done extensive wiring when doing home improvement projects at my last couple houses, including doing all my own wiring work to completely finish two basements that had started out completely unfinished--so I'm not an electrical rookie, either. But for some reason, the instructions and diagramming that came with this unit were nearly impossible for me to figure out. But I did, eventually, figure it out. Now that it's installed, it functions just as you'd want it to and it looks great.

Just what I ordered.
