BN-LINK Digital Cooling Thermostat Controller, Temperature Controlled Outlet for Attic Fan, Exhaust Fan, Cooling Devices 40-108°F, 8.3A 1000W

I recently installed a ventilation fan in a media closet to keep heat levels down, and wanted a way to control the fan via thermostat without spending a bundle. This product was just what I needed. It's not complex, it's a thermostat controlled 120V AC outlet...nothing more fancy than that. I set mine at 75F and it reads temperature to a precision of one tenth of a degree F. The temperature reading probe is on a bit of a cord with a suction cup, so can be located a foot or two away from the main unit.The unit itself has a mounting hole on the back and can be hung on the wall. I was worried that it might "flicker" as it bounced around the set operating temperature, but seems to smooth that out and doesn't seem to suffer from that flicker-effect.I didn't see any compelling reason to buy the upgraded, newer version of this myself, as this one met my needs perfectly. A good choice here, if this is what you need!

I just finish assembling my rack I purchased from Amazon. I used the thermostat to turn the fans on to cool the amplifier it was easy to program and it looks great. I tested it out with a trial run blasting my stereo for about three hours,but it never got warm enough to kick on . the thermometer did get up to 95. So far I am really happy with it. I am not sure what temperature to set it at . I have it at 104 . It will need more testing ,I will have to crank the volume up for a much more extended time.

Didn't even need the directions.. hold set for a few secs until flashing, set temp, press set button again. Super simple, great design! 5 star, would recommend!

I got this to use on a twin-tap EdgeStar beer kegerator in which the thermostat has never worked properly and kept freezing the lines and sometimes even the kegs.I have two- 5 gallon kegs of “classic American lager” that tastes best ice cold and this device only goes down to 40 degrees Fahrenheit.It would be okay for good craft beer - IPAs, stouts, etc. because those taste best at around 42 degrees, but not for “cheap” beer LOL.What I did to overcome this was I wrapped the probe sensor in some insulating foil bubble wrap with zip-ties and placed the probe on the side close to the door seal where I know it probably has some air infiltration and would read warmer than the main part of the fridge.It worked and the beer comes out at around 35 degrees, which is good enough when dispensed into an frosty mug.It was literally half the price of another brand I use, probably because of the 40 degree issue, so that's a plus, especially for this use.We'll see how long it lasts, but even the more expensive units usually go out after a year or two.

System works great! I use it to turn on fans in my high ceiling shop to circulate air

I live in the Southern US and our daytime temps often get over 95 degrees. I love using these devices for running a regular old fan for my chickens during the hot season. I set it at 85 and the fan comes on once my coop reaches 85, and it cuts off once it gets a degree or two cooler.Pros: super easy to set desired temperature, usually lasts several yearsCons: stops working after a few years

Per the spec sheet that arrives with this BN-LINK temperature controller, this unit can only handle 4 Amps for INDUCTIVE loads, such as fan motors! The description on this product falsely claims that it can handle 8.3 Amps for circulation box fans, but ALL electrical motors are INDUCTIVE loads! My 18 inch attic exhaust fan uses 5.6 amps, and thus I could not use a device rated for 4 amps to run a motor using 5.6 amps. I reviewed ALL of the reviews before I purchased this product, and wondered why many users complained that this product failed after using it for a year. If the reviewers used these controllers on fan motors that require more than four amps, it is a wonder that the controllers lasted for a year! - Amazon, please update this product listing to state that while this product can handle 8.3 Amps of RESISTIVE loads, such as lighting and heating, it can only handle FOUR Amps for INDUCTIVE loads, such as fan motors. The product does seem to be quite accurate, insofar as temperature control, but I could not use it for the attic fan motor that I had purchased it for.

It’s only been 2 days but it works perfectly. I use this to operate a fan in order to cool a solar inverter. I cannot comment on it’s longevity but being a simple device I have no reason to believe that it wont last. The build quality is very good and heavy duty. The price was way below the big building box stores which only carried mechanical devices that require one to hard wire everything. This is plug and play. I would buy again.
