Applications: use with inline duct exhaust fan in grow tents, greenhouses, hydroponics, kitchens, basements, garage to adjust fan speed and control temperatures. Set the startup temperature: rotate the temperature setting adjustment knob, adjust it clockwise or anticlockwise. Example: the set temperature is 77°F, if the environment temperature is lower than 77°F, the fan will not work. If the environment temperature is higher or equal to 77°F, then the fan begins to work. Adjust fan speed: one control switch for 3 speed: high, med, low. Variable speed adjusted clockwise to increase and counterclockwise to reduce, adjust to the required speed. Hanging tab: hang the controller however you want from the eyelet tab. It can hang flush with the wall or from a variety of hook sizes. Specifications: temperature control range is 59-95°F(15°C-35°C). Rated voltage is 120V AC 60Hz, max loading: 6A 750W. Can switch Celsius or Fahrenheit display. Three-prong grounded plug: the angle of the outlet keeps cords from getting tangled. Easy to plug-in. Please do not immerse the controller or probe into water.

Ok I guess
I ordered the 2 pack. Arrived undamaged and pretty quickly. Pretty straight forward to use. Temp cord is plenty long enough. I assume the sensor is at the end of the cord. I am using in my greenhouse to control the fans. One fan per controller. I don't like the fact that there is only one mounting hole (as clearly seen in the pictures). If you want to mount it level, you have to support the weight of the cord on the plug in side. I also noticed that in the morning when the temp is just at the setting that I have them set on that the fans seem to hum a little like they are only getting a little power and then they turn off. Sometimes the fan will just start to turn and then turn off. I'm not so sure that is good for the electric motors. Especially the humming. I would be quite upset if I had $450 worth of fans burn up. I keep the fan controller on high and my fans on high. I have the temp probes located away from the fans and out of the airflow to avoid cycling the fans off and on. As of now I am unsure if I am satisfied with these. I like the idea of the temp controlled fans but I could just use timers as well. I'll give these a little while and see.

This item is working perfectly for me .

Love it but can we get one change??
I understand that America is far behind the entire world... But I'd pay an extra few cents to have both Celsius and Fahrenheit labeling on the product...

Works well on PSC motors
Listing warns that device cannot be used on “shaded-pole” motors, so beware. This is why only 3-stars. This type of (capacitor-less) motor is ubiquitous in small A/C fans (ex. Vornado, and others). This speed-control unit works well on PSC motors (permanent split capacitor), which are also very common. This larger sized (15A) iPower unit has a replaceable fuse. This is nice. And with the higher capacity, this unit is preferred over their cheaper 5A fuseless version. Nice to have on-hand. BTW the newer DC-version of Vornado fans, makes this kind of device not needed. If you want an infinite choice of fan blade RPM (bedside table), you owe it to yourself to review Vornado’s (more expensive, but much more efficient) line of white housing DC table fans. The Vornado model 133DC is the pick of the litter, all the larger versions suffer from bad NVH issues.

Just What I Needed
I purchased this Variable Vent Fan Speed Adjuster to use on a large Harbor Freight fan we have in our Love Shack because the fan was very loud. We can control the fan speed by turning it down to a lower RPM speed and lowering the loise level of the fan. I works great and I highly recommend it.

does not go slow enough
speed not slow as i,m used to on other control.

Adjustments
They don't have differential, on and off with in a fraction of degree
