Inkbird Dual Stage DV 12V Digital Temperature Controller Fahrenheit Thermostat Heating and Cooling for Homebrewing Brew Fermenter Fridge Incubator Greenhouse

Just what I needed. I am using this to control the temperature of a peltier water cooling device I am building and it works flawlessly. It is fully programmable to heat or cool. I have it set to come on when the water reaches 68 degrees F and turn off at 65 degrees F. You simply set the on temp and the difference, which in my case is 3 degrees. It has a built in high temp alarm that engages and automatically shuts everything, except the alarm, down if for some reason it fails to to cool below the set high range....for instance a fan or water pump failure. It will protect the peltier from thermal runaway. I do recommend using an appropriate size fuse inline for the load. It comes with a wiring diagram affixed to the top as well as relatively clear instructions on how to program it. Another model I had of this same device had no instructions and I had to get on YouTube if learn how to program it. This one has clear instructions. Note that the orange clips slide off the back so that you can slide the controller into a panel and then slide the orange clips back in place to hold it securely in place. The instructions did not show this but it was easy enough to figure out. This model has the ability to select either F or C to display. The other one I had only had Celsius. It comes in 12v DC or 110V DC so make certain you order the proper one for your needs. The selection of Heat or Cool is carried out by which terminals you connect to. There are two terminals for heating or the other two terminals for cooling .No need to program the function. It automatically knows your selection by which terminals you are using. You need to make a wire shunt to run from the positive input to the cool or heat terminals depending on your needs. I can see where this would be a great method of providing temp control for incubators, brood boxes, or heat lamps for pets. Note that it has a 10 amp rating. If you need to carry a bigger load simply connect it to an appropriate sized relay. Know your load and stay safely under it or as I stated use an appropriate relay. I prefer using relays with built in diodes to prevent flyback voltage from knocking anything out. Get one......and have fun.

This is an excellent little temperature controller. BUT is does not have WiFi contrary to the specifications listed. Other than that, it does everything you would expect. The label on the device just shows 12V connected to pins 1 & 2 but there are no markings and no indications in the instructions about polarity. Terminal 1 is +, and Terminal 2 is -.

Saved me a lot of money. Used this to monitor my chest freezer. Put a 12 vdc buzzer on it to let me know if there is an issue and it did. Freezer failed and alarm went off at the setting of +10 deg allowing me to save a freezer full of meat. Have three of these in different freezers and it's great piece of mind. PS it's on a 12 battery back up along with motion detection 12v lights over the freezer. It's small but awesome.

This works as advertised. I previously bought a cheaper one, and had to return it due to the relay not coming on reliably. This thermostat has a better quality relay. I'm taking away one star for the instructions, and general difficulty in getting it set up. I almost gave up on the first try. Came back fresh the second day and got it working. Most stuff I buy is pretty easy to set up. This was not one of them. What ultimately matters is how reliable this thermostat will be. It's made of good quality parts, so I'm optimistic it will hold up.

Buen artículo por su precio

Easy to install and operate. Used it to replace failed thermostat on boat refridgerator/freezer

The 20+ year old Winnebago RV I purchased recently came with a Suburban propane furnace, whose "thermostat" has no temperature markings, and whose minimum setting burned a lot of propane, keeping the cabin hotter that I needed to prevent the plumbing from freezing in winter. I wired this thermostat in its place, and it have been able to reduce the propane usage dramatically. The instructions were a little confusing, but reading other reviewers' comments helped me to figure it out. Here's my two cents worth, with apologies to those who may not appreciate my epiphany: the TS, or Temperature Set Value, is the target temperature you want to have; the DS, or Difference Set Value, is at what number of degrees below the TS you want the unit to power the heat cycle; AND it is the same number of degrees above the TS that you want to unit to power the cooling cycle. In my case, I wanted the furnace to kick on when the temperature at the sensor dropped to 35 degrees F, and to shut off when it climbed to 45 degrees F. So I set the TS at 45 degrees, and the DS at 10. Note that this means that the cool cycle kicks on at 55 degrees. But I don't have anything wired to the cool cycle terminals, which, as Inkbird tech support has confirmed to me by email, is innocuous. I want to add one other note: although some wiring diagrams don't show it, other reviewers are right: the HOT power supply needs to be connected to the power supply terminal, and to the positive terminal for heating (and cooling, if you use it).

Had a very similar looking temperature controller from another company on Amazon that had higher ratings, but I managed to short that one out (my fault not the controllers) so I needed to order another one to control my astro camera cooling project that uses a Peltier chip. This one I found has more features than the other and works just as well if not better. For instance, this one can be set to display the temperature in either F or C. The other one I had would only display Fahrenheit. One thing that I preferred about the other one is that its remote temp sensor was a slender metal rod while this one has a plastic nub. This one might be slightly slower to react to temp changes, but if so only by a few seconds so certainly not a deal breaker. In any case, been using the controller for about a month now and no problems.

Easy settings, manual is provided. Occupies less space. Works as expected!!

Uno de los 2 controles que compre no tiene el cable con sensor

Easy to install and setup

Problem 😔

Its not showing display,and not 🚫 working
