Review: Works perfectly! - As an electrician, I was skeptical how well this item would perform but for the price, I gave it a shot. I have to confess that it is still confusing to me how it actually functions but it does. I use it to control a blower on the back of my wood stove that is controlled by a variable speed switch. This item perfectly turns the blower on when the stove is heated to approx. 120 deg. and shuts it down at 90 Deg. I placed it on the back upper corner of the stove and have not had to move it at all to maximize its performance. I also connected it to a 3 point on/off/on toggle switch from desertcart in a box so I can either control it manually or on auto just in case. Still don't completely understand how it works but I highly recommend it!
Review: Super easy and works great - Worked perfectly. Been three years. Happy with my buy.

## Questions & Answers

**Q: Does this come with an enclosure to cover the connections?**
A: no it does not I built a cover out of a old fan case

**Q: Would this work on a bathroom exhaust fan?**
A: Yes, I am using this controller on a bathroom exhaust fan and it works very well. It does have a minimum fan speed though so you can only slow it down so much. But that is pretty slow.

**Q: My blower has a variable speed control knob. How do I attach the wires?**
A: It will no effect anything you attach to it this nothing but an on off switch

**Q: I assume this mounts inside the stove, right? My old one is in a hole where the sensor was sticking out.**
A: This is not a thermal coupling as would be found in a oven. This has a magnet on it, that the large circular area. I used it as a sensor on a pipe and used a metal tie rap. The part with the electrical connectors is the electrical thermo disc switch. Only its lower metal surface should be directly exposed to the heat. Such as the other body of a oven or hot water heater or in my case a small boiler pipe. The non-metallic body of the thermo disc is not intended or may not be designed to hold up to the direct heat.

### ⭐⭐⭐⭐⭐ Works as described
*by M***T on September 29, 2018*

Not being an electrician I can't speak to the technicalities on this switch. it doesn't operate like the old rheostat switch did but it still works. (Rheostat meaning variable speeds or voltage applied...like a dimmer switch) it seems to have a much lower end to it where much of the travel of the knob creates very little actual fan speed. That could be relays, circuit boards, warp speed... But it is not an OEM equipment and I don't know if all the electronics are matching or agreeing with purchased switch, but enough matches, the size the fit the 110 AC two wire type splice into the stove controls. Turn it all the way up and I get full fan speed, turn a third down and it's barely turning. So I've got two thirds more knob and nowhere to go with the fan speed. That'll be fine for me. Some of the lower reviews sound like they're using this switch for unintended applications. It's a woodburning stove variable fan switch, designed to control the air blowing off your stove into the room, thus heating your room. Applying this switch to computer fans, and bathroom exhaust fans can only give you extreme unintended consequences, that may lead to poor performance or just dangerous. Use it for a wood burning stove. Use a dimmer switch for your exhaust fan (lutron is the best) and go to geek squad to fix the computer or you're going to end up like "the fly" or traveling back in time or sumptin'...
