Inkbird ITC-308 Digital Temperature Controller Outlet Thermostat 2-Stage 1100W with Sensor Reptile Beer Brewing Kegs Fridge Cured Meat Breeding Growing

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.

This temperature controller is a very easy way to control the climate in an area you cannot always be around to control manually.One merely has to program the minimum and maximum temperature that is suitable. There are two electrical outlets labeled heating and cooling, and this is where you plug in the power for your heating and cooling systems, respectively. So for example, you could plug in a space heater and a AC unit, and when the temp gets too low, the heater is turned on automatically. When the temp gets too high, the AC unit is turned on automatically. When the temp reaches the programmed ideal, both units are powered off.There is a separate temperature probe which can be placed roughly 6-7 feet away from the unit, to more accurately measure the temperature.The unit has two screens, which will display different information, according to what you are doing, programming or simply checking the monitor. In most cases, one of the screens will display the current temperature, and the target temperature. There are also round LEDs which indicate at a glance whether the unit is in heating or cooling mode.From the day the unit arrived, it was worked perfectly, without a hitch. For an indoor hydroponic garden, temperature is important, and one can rest easy relying on this unit to control the temperature.PROS:+ Separate temperature probe for added accuracy+ Easy to program+ Easy to read main screens from a distance+ Labelled outlets for the cooling system and the heating system+ Wall mountable with a screw (not included)+ Sturdy construction+ Programming documentation includedCONS:- Probe cable is only about 6-7 feet in length.

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.
