BN-LINK Digital Temperature Controller Heating Cooling 2-Stage Outlet Thermostat Controller Plug for Reptiles Aquarium Carboy Homebrew Breeding Fermenter Seed Germination °C/°F -40-176°F 15A/1875W

I've been using this product for a few years now and it is genuinely one of those rare products that is just uncompromisingly good. At the risk of sounding like a review robot, I want to elaborate on my experiences with this device and why it's been one of the best electronics I've bought from Amazon. To clarify, I have only ever used this device for controlling the temperature of my living space, not for any agricultural or misc purposes. Despite this, as someone who is a nut for home automation, this device serves its purpose perfectly. HEATING OUTLET, COOLING OUTLET The device works by providing electricity to one of its two outlets based on user-defined conditions. These outlets are helpfully labeled "HEATING" and "COOLING". Having a single device that can control both a heating solution and a cooling solution is SIGNIFICANTLY more intuitive than having two separate systems, one for heating and one for cooling. A WIFI-FREE SOLUTION Many similar devices are wifi-controlled. That can be a good thing if that product allows for more advanced setups like schedules, but in positions like mine where I live in University Housing (where IoT devices are not allowed to connect to the internet, only complete devices like Computers and Phones can) having an analog system has been ESSENTIAL. Being able to just plug the device in and push a few buttons instead of filing an application with the property holder to add a special exception for the device on the network is much more elegant. PERFECTLY ADEQUATE CONFIGURATION OPTIONS The device has plenty of variables that can be used to create the exact behavior you want. Some highlights include: SU - "Set Unit" - The ideal temperature you would like Hd - "Heating Differential" - How many degrees colder than the Set Unit the temperature must be before the heat comes on. Cd - "Cooling Differential" - Home many degrees warmer than the Set Unit the temperature must be before the cooling comes on. PT - "Time Differential" - After the system reaches the SU, the system will wait for at least PT number of minutes before allowing any outputs to turn on. By mixing and matching Hd, Cd, and PT it is possible to create very specific behaviors. I will elaborate on this in the next section. GREAT FOR SPREADING OUT CYCLES One way I use the device is to control my air portable conditioner. By default, my AC will turn on when the temperature drifts by more than ~1*F from the target. This can result in a lot of really short cycles that can be distracting. By configuring my device with a Cd of 3 and a PT of 4, I can make it so that my device runs for longer but less frequently. This is ideal given how jarring the transition in volume between idle and operating modes in portable air conditioners. DURABILITY The device is extremely durable. My device has seen a fair bit of abuse and functions exactly how it did when I got it. I also appreciate how the cable that connects the device to the outlet is very thick, as this pretty much ensures any devices you plug into the outlets on the device will not be drawing too much power for thin cables to handle. My only consideration is the rather flimsy cable for the temperature probe. As long as you are gentle with it it will be fine but because its connector is a 90* angle it can sometimes be easy to bump it. That's all I've got for now. In a world where products are getting cheaper and flimsier, it's reassuring to see products that are durable and practical. No gimmicks, no risks, if you want to control a heating and cooling system through an external analog device I really think this is the device for you.

This is a great temperature controller. There’s multiple outlets for if you need multiple heating elements. It’s perfect for my pet tank. I use it for my hamster tank during the winter, just in case it gets too cold and it’s reliable. It comes right on at the correct temperature that I set. I have two ceramic lamps connected to it. It’s a good price for a controller that has two outlets, so I can even split it for another lamp in another tank.

Very good temperature controller. The display is bright and easy to read, and the temperature control is very precise. Installation was simple and it works perfectly.

This temperature control (the T10 model) worked really well after I jumped through the hoops of setting it up. I used it with great success in my greenhouse for several months. The issue I ran into occurred as the temperature dipped in the winter, and I added a second heater. I was careful to put them both on the medium temp setting to stay under the maximum watt rating of the temperature controller. Apparently, the inrush current of the second heater overloaded the controller. So I take out the supplied manual to troubleshoot, and immediately notice two glaring problems. The documentation references both an overload reset button and removable temperature sensor that my device does not have. So I look at the Amazon listing, and realize that there are two models offered for the listing: the T9 and the T10. They apparently decided to use the same manual for both models. I doubt that this was a fluke, because I have two of the T10, and they both shipped with incorrect instructions for troubleshooting. So I figured that since one was dead I may as well open it up, and discovered that there is a replaceable fuse inside. If you manage to get yourself in the same situation that I did, it is possible to solder a new fuse in place. The original appears to be 15A. Would this void your warranty and set the liability in your lap? Absolutely. Will it safely solve the problem? Maybe. I still think this is a good product, but sending out the wrong instructions is inexcusable. If you are considering buying one of these, I recommend spending a couple dollars more for the T9 model, which has a replaceable temperature probe and resetable fuse.

Very good, I use it in my fish tank, which can control the temperature of the fish tank within a reasonable range to prevent accidents caused by dry burning of the heating rod, which I think is very useful.

le prix est excellent assez difficile à comprendre pour la programmation une première fois mais une fois réglé tout va bien. je l'utilise pour chauffer mon bassin de koi extérieur. évidemment l'unité est caché des intempéries

Fácil de usar, permite encender y apagar aparatos de calefacción, ventiladores, refrigeradores. Ejemplo de uso, hacer operar un refrigerador en un rango de -3C a 3C Parametros que se configuran con Set y Up/Down SV o SU -3C CD 6C Al llegar a -3C se apaga, y encenderá 6 grados después a los 3C Para fermentar entre 16C a 21C SV 16C CD 5C

Works good, turns on and off my fans when it needs to. Exactly what I needed

Regular calidad

This controller was super easy to setup. And an absolute life saver for my plants, and myself. Canadian winters are cold, so growing indoors can be tricky without the proper temperatures plants cant theive. Well with this BN Link controller its simple plug and play.
