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

Works really well for my cheese cave fridge. I have an old mini fridge that, at its warmest, will stay at 40F. Using this, it's easy to keep my fridge at 55F for cheese aging. It has about a 1 degree range (keeps my fridge from 54-56). I've checked it with other thermometers, it's accurate. I love that the display is not right where you plug it into the wall, as my outlet is hidden. I hung it on the wall right next to the fridge to make it easy to check on it. Very easy to set up as well!

works great we have a exhaust fan for our chicken coop keeps them happy and cooler.

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!

They work very well and are easy to use. However, they are not surge protectors. I recommend plugging them into one. I have had to replace the fuse in both of mine because of thunderstorms. Replacing the fuse is cheap, but it is not easy. If you are unfamiliar with basic electronics, don't try; just buy a new one and plug it into a surge protector.

Very easy to setup and works great on the fans in my server rack

Excellent temperature control

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.

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
