My whole house fan had a on/off switch and a switch for hi/low. I wanted to get rid of both and this worked fine. The one thing I don't like is it sticks out from the wall 7/8" and then the knob another 3/4". It does allow me to turn it on/off and adjust the speed all from one switch. Very easy to install. Good quality material too. Happy with this product.
Heat sink is large--and is outside the junction box--to accommodate up to 6 amps (see photos). I only tested it briefly and it worked fine with a NuTone exhaust fan. Since the fan I have only pulls 2.4 amps, I went with the 57W (3 amp max) because that unit doesn't have a protruding heat sink.
My whole house fan is about 20 years old & I started worrying that the pull chain could break when turned on. Found this Broan-NuTone variable switch & couldn't be happier with it. It does stick out from the wall as it has a heatsink but that wasn't a problem as I put it in our pantry closet. I love that you can set the speed to what you need for controlling the airflow...
I returned it as it was not what I wanted after I received it. It sticks out on the wall like an industrial timer. Not what I wanted in our bathroom.
