After having done some careful research, I bought two of these devices here on Amazon for use in controlling the heaters in a smallish insulated outdoor building (an Amish barn style shed used as a workshop). They both work great in the intended application, and, best of all, setup is easy, straightforward and quick; you only need to spend about two minutes reading the instruction manual before becoming a pro in configuring the various settings that you might wish to tinker with. And now, a few notes about the device, some of which are in response to comments made here by other reviewers: Setup of the device is easy once you have spent two minutes reading the instructions. However, as is true of the vast majority of instruction/user manuals that accompany devices such as this that are made in China, the printed instruction/user manual provided with the device is nearly useless, due to the fact that it is so small in size and consequently the print font is very tiny and difficult to read. So, I did not even bother to try deciphering the nearly-impossible to read user manual that came with the device, and rather, I went online and found the InkBird website, at http://ink-bird.com, and then quickly located the downloadable manual for this device in PDF file format, at http://ink-bird.com/asset/file/ITC-308%20V2.1%20EN.pdf , downloaded it, and printed the three most important pages to me out of the six pages in the manual. The cord on the remote temperature sensor is a bit over 6 feet long; I provide this information because others have asked about the length of the cord on the temperature probe. Although one or two other reviewers have stated that they feel that the temperature display of this device reads about 1 degree C too high (compared to reliable & accurate thermometers), this has not been my experience. I have found the temperature calibration of this device to be very accurate; it is totally in agreement with my other digital thermometers. Please be aware that while the ambient temperature display shows temperature in 0.1 degree (F or C) increments, as does the Set/Target Temperature display, the Set (i.e., target) temperature can only be set in one degree integer increments. So, you can select a Set temperature of 90.0 degrees, or 91.0 degrees, but you cannot select a Set temperature of 90.4 degrees. These units work great, the displays and thermostatic function are very accurate, and the units are very reliable. I would buy more for other applications in a second if any such need arose.

I am very pleased with the performance of this Digital Temperature Controller. In fact I bought two of them. I have used it to control the temperature of Kombucha, Spirulina, and several other items. It can control 1200 watts at 110 Volts. That means you can plug a standard chest freezer or refrigerator into the device and control its temperature to be something other than normal appliance operating temps. I have also used this to sound an alarm when cooking temperatures get to a specific number. Works great when trying to optimize Sulforaphane in broccoli! After you get used to setting the unit, it becomes easy to do. Just hold the set button for 3 seconds to get into the programming mode. Then scroll through the options. When done, hold the set button for another 3 seconds to lock in the program. No need to scroll through all the options. The main function you might use would be the TS which is Temperature set value. HD and CD which is how many degrees difference you want to allow between the set value and the actual value. (Usually only a degree or two) You will also want to set AH and AL which will activate an alarm if your temperature gets too high or low. There is a helpful indicator light that will show you if the unit is in heating or cooling mode. When in heating mode the unit will apply current to the 120 V “heat connector”. When in cooling mode the “Cooling” connector will be energized. The connectors are standard 120 V receptacles. My experience is, this unit is very reliable and keeps the temperature of your project very close to the temperature you set. I would not hesitate to buy it again or recommend it to a friend. In fact, I did recommend it to a friend. He wanted an alarm to sound when his deep freezer fails to keep his frozen items at the desired temperature! Works great for him, he loves it too! I have no conflict of interest in writing this review. I am just a happy customer and I am happy to report that I was able to resolve a minor issue with the seller and found them to be very supportive and professional.

Very clever device that will turn on a heater below one temperature and turn on a cooler above another temperature. You can vary the amount of overshoot or undershoot, the time delay before a cooling appliance will be switched on (to protect the compressor), the alarm point for wide excursions from the set temperature, and, of course, the set temperatures (C or F) for heating and/or cooling. You don't have to use both heating and cooling. For example, if the ambient temperature is always higher than the desired temperature, you don't have to add a heater. This would be the case if you are using a refrigerator for a wine cooler, for example. Similarly, you wouldn't need to add a cooling appliance if you only needed to keep something warmer than ambient temperature, such as seed sprouting or terrariums, for example. The temperature probe is small and on a fairly thin insulated wire (about the thickness of a cell phone charging cable). I mention this because you will need to stick that probe where the temperature is being controlled, such as through the gasket of a refrigerator or in a terrarium. My only complaint is the Sino-English instructions and the odd shorthand used in the display setup for each feature. It took a while to figure it all out, but once I did, it's really a very nice and versatile unit. I may get another.

I have been looking for something like this for years. I had no idea it existed until I ran across it in a lightning deal. Anyways, coffee tables and couches obscure the 2 heating vents in my living room. I have fans in front of them to "boost" the air flow from under the coffee tables because all I am doing is heating up the coffee tables when the heat runs without them. The problem has been that I have to leave the fans running 24/7 so that I can get the heat from under the tables. The flip side of this is that I also get some undesired cooler air when the heat is not running because the fans never shut off and I have an annoying breeze when the heat isn't running. Enter the Inkbird thingy here. I plugged the fans up to a splitter and then into this gizmo and set the cooler temp to 85 degrees. Now the fans only run when the furnace runs!!!! I have considered other way more expensive solutions to this problem before trying this but this is by far the cheapest way to fix my problem AND I have discovered that my heat is actually running less since with this thing and I don't have to deal with the continuous annoying breeze from the fans when the heat is off!!! I also think that the Inkbird will actually pay for itself in a couple of months since my furnace is running about 30% less!!! **REVISED REVIEW A COUPLE OF YEARS LATER** I have moved on to a new house. The master bedroom is the farthest room from the furnace. It doesn't seem to get as warm as the rest of the house even after playing with closing vents in other rooms. I pulled out the inkbird from the old house and set it up with an electric fireplace heater blower I rigged up in a box that I put over a heating vent and my problems are solved again. As soon as the heat in the furnace duct hits 90 degrees the inkbird turns on the fan and it sucks the heat thru the vent and out into the room. I am able to increase the temperature in the room by about 3 to 5 degrees by varying the temperature on the inkbird. The lower I set the temperature on the inkbird, the longer the run time I get. This little setup has changed the airflow coming out of the register from a trickle to the equivalent of having a powerful plug in heater in the room. The best part is that the inkbird along with the electric fireplace fan only pull about 33 watts of electricity when running as compared to about 1200 watts from a heater. I use about 1.9 kwh of electricity a week with this setup as measured thru a smart plug. This means that I use less than 25 cents a week or $1/month to boost the heat to my master bedroom using the inkbird and the fan. The Dyson hot/cool heater that I had rigged up thru a kill o watt measuring device used roughly 75 cents of electricity in 1 day to heat the same space and the Dyson hot/cool heater is one of the most energy efficient heaters on the market. Now if you figure the daily rate of 75 cents and multiply that over 30.4 days per month on average you get $22.80/month to run the heater. The inkbird and fan cost $1/month to get the same result. If it would stay cold all year, it would cost $12/year to run the inkbird/fan combo. It would cost $274 to run the heater. This is a savings of $262 per year.It doesn't so YMMV. BUT... I can also use this setup during the summertime to boost the a/c flow coming out of the vents. :)

update 1: worked great last night. update 2: found a work around to the warm wires (sort of). if im no where near my desired temperature, in the future i will just directly plug the a/c in to an outlet and then plug into the controller later. now that its cold in here it is doing an excellent job going on and off and my ac only runs 10 minutes every 20 minutes during the night and morning. update 3: i think my "T" shows up as an "E" but missing the top part of the E, small glitch. knowing how electronics work though, a small glitch can turn into a big one later. still love this product and as long as it keeps working my review will remain 5 stars. my camper AC is jimmy rigged to plug into an outlet. it sometimes freezes up in the early humid tampa mornings. i had it on a on/off timer but the timer just gave out after only 2 months. just got this thing programmed and running. after a hour of running ive noticed one thing. the power cord is getting warmer. going to check it a few more times before bed but im really hoping it can handle it. the issue is, the device has a cord going out to receive power from an outlet, and another cord going out to plug your heating/cooling device in. so the current has to go through the device. my suggestion to the manufacture would be to go a gauge (thickness) up in their cords and solve this potential issue/hazard. also making it one cord coming out that has the receptacles and the plug all on one cord would reduce a lot of resistance. i would gladly pay extra for more heavy duty cords. i am very excited to plug a tiny space heater into it this coming winter and have a temperature controlled environment. here in FL its normal to use an air conditioner and a heater all in one day. We only get about a month or 2 of tolerable temps where no a/c is needed. im really hoping to keep it around 70F in my camper 24/7. wish me luck! on top of thicker gauges for the electrical cords i would like an option to have the controller go past the desired temperature by a certain amount. so say you select 77 as desired and 67 as shut off. it will turn on at 77 and off at 67, or opposite if youre heating. that would be really cool for my application. i do have it set for 10 minute breaks before off to on, which technically does the same thing. so no stars reduced! 10 minutes is the max amount of minutes you can set for breaks between on/off, which i think should be changed to 60. 10 is just barely enough in my opinion. strange they would make 10 max, youd think the more control they give the consumer the more useful the product would be.

These units work very well and are very easy to setup to your needs. I use 4 units in different locations. One unit controls 3 small greenhouses heating sys by plugging in a quad receptacle to the heating outlet on the unit. and then running extension cords to the different greenhouses. the temp sensor has a nice log lead so you can locate the sensor easily wherever you need it. Only consideration is you must resist the temptation to "over" amp the draw on the unit. Still 1050 watts gives you a lot of output from the unit. It is the goto unit to control heating units, or cooling fans. very dependable and very well made. Inkbird is a solid build! I have 9 other Inkbird controllers of different types controlling different type units. Only unit failure was a direct lightning strike!
