Review: Actually just a Solid Choice - 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 desertcart. 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.
Review: Great temperature controller - 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.
