BN-LINK Digital Cooling Thermostat Controller Temperature Controlled Outlet for Attic Fan Exhaust Fan Cooling Devices 40-108 F 8

Works well for a few days now, kicks on at the set temp. It’s been reliable so far. Installation was simple—there’s a keyhole slot on the back to hang it on a screw. My only complaint is that it has just one mounting slot at the top, so the bottom isn’t fully secured. It includes a wired temperature probe, allowing flexible placement. I kept mine near the unit, and it reads accurately. The digital display is bright and easy to read, even from across the room at night. Programming is straightforward: hold the “Set” button, then adjust with the up/down arrows. Pros: Compact, accurate, bright display, easy setup Cons: Only one mounting slot; temperature adjustment requires holding “Set” first. So far, so good, happy and hope it holds up long term.

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! Read more

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! Read more

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. Read more

this thing works awesome . just plug it in hold the up button for 3 seconds for Fahrenheit ,hold the down button for 3 seconds if you want Celsius, hold the yellow button for 3 seconds to set the time up or down.. hit the yellow button again and it set put the probe wherever you want the temperature to be adjusted ...I drilled a hole in the side of my solar panel this unit is not waterproof so if you use it out door like I am make sure it's protected and so is the probe... I'm using it as a thermal on off switch for my solar pool water heater I made a solar panel with 50 ft copper tubing inside glass encased [2 of them ] I wanted to have this turn on a sump pump sitting in the pool 18 inches below surface..I wanted this to come on when the solar panel got hot 100f... not on a timer because some days gets rainy... I have it hooked up to this sump pump... that pushes water to solar panels that are 6 feet below the pool surface ....15 ft away from the pool 100 feet of half inch outer diameter copper tubing works great... https://www.amazon.com/your-orders/pop/ref=oh_aui_i_d_old_o6?_encoding=UTF8&gen=canonical&lineItemId=kgjirqlpkjsrsny&orderId=112-8601220-8637060&packageId=1&returnSummaryId=&returnUnitIndices=&shipmentId=DZ6wthHSb It is a 52 inch high 12 foot by 24 foot Intex swimming pool the sump pump is 18 in below water surface With 2. 24 inch by 5 foot glass pane solar panels ...each 50 foot copper tubing inside it is able to raise the pool temperature approximately 10 degrees I'm at 60 gallons per hour As in water coming from pool is 70° going back in pool at 80-95f Over 6 hours it raises the entire pool somewhere between 1 and 3 degrees more then just the sun itself per day The pool is 8600 gal so the entire pool os turned over in 14 days 10 f warmer then just Sun itself Works especially good at the beginning and end of season to extend your pool use Read more

Works very well for my temperature controlled fan. My garage gets a bit hot in Florida so it helps circulate the air... The only thing that would be a great add on would be to be able to have larger than 1 deg C for the on and off setting. it would be nice to have a second choice or Hysteresis of 3 deg C... Read more

I was really hoping this item would solve my attic ventilation issue. It came quickly, but I soon found it was not as expected. This unit does not allow the setting of a temperature offset, and when I set it for a specific temp to turn on I found it to be 18 degrees off. With no way to calibrate or adjust, in my case it will not work for me and I will be returning it. Read more

I installed this controller for the exhaust fan in a generator enclosure. I like that it has a remote sensor that can be located close to the exhaust to turn on the fan when the generator is running. Seems to be accurate with temperature measurement. Note that it has a 3* dead-band when cycling on/off. Easy to mount, although I would prefer 2 mounting holes to maintain a stable position. Setting the set point is easy, instructions are clear. Just plug it in to power, plug in the fan and set the temp. Shows ambient temp when plugged in. We'll see how long it lasts in a hot environment. Read more
