    Nice upgrade for an egg incubator
    It takes a little time, at least for me anyway, to get the hang of the setting controls. The manual is key especially if you only use it every 2 - 3 years. Otherwise it is a nice upgrade for an egg incubator. I enclosed mine in a vented case to protect the wiring and connections.

    I was almost put off by the negative reviews, but I got this thermostat for my leopard gecko egg incubator. I needed something that would keep the temp at 88* F constantly. Although this T-stat was a little difficult to wire in initially, and required some parts it didn't come with (a plug, outlet, jumper wire), which is a small price to pay for such an inexpensive thermostat, it did it's job very, VERY well. I already have hatched healthy leopard geckos from two clutches, and I have another clutch that should hatch in about 3 days. The eggs are very healthy and this will be my first 100% hatch rate EVER. I also hatched cricket eggs in the incubator controlled by this T-stat.

    The T-stat has kept the temperature within 1.5* F in both directions constantly for several months now. I have been EXTREMELY happy with this product, so uch so that I ended up getting another one specifically for my cricket eggs. Same great results.

    Another great thing with this T-stat is that it's small size and convenient shape makes it very easy to build into whatever you are using it for, in my case an incubator.

    The only reason I don't recommend this for everyone who needs a T-stat is that wiring is a bit difficult. It requires at least some prior knowledge of electronics, and it's definately not "plug 'n' play". I definately wouldn't recommend anyone who doesn't have experience with electronics try to use this. You are dealing with 120v AC. Show some respect! But after it's wired in it works well.

    There are also two diagrams on how to wire it in, which are both feasible but it is a bit confusing. I recommend that you follow the colored diagram on the FAQs sheet included with the product, because with that diagram all the "hot" wiring is inside the unit. That will reduce the risk of shock, fire, etc. The yellow, ground wire on that diagram is unnecessary, though it is safer.

    Overall, it's a great thermostat for a great price. I will definately be using it again!

    I love these, and have bought for several purposes. The included K type thermocouple is accurate enough to measure to .1 degrees resolution. From the few times I've used these, they are very close to actual temperature (+/- 1 degree), and do offer a temperature "shift" in case you do need to make an adjustment. I've used this to replace a mechanical thermostat on a 1930's westinghouse refrigerator, and it works great. I've also used this to build a chicken incubator. Again, it works great. it has an internal relay that handles quite a bit, and you can always run it through a "solid state relay" to power anything you need to. If you are using this for a refrigerator rebuild, I highly recommend you also buy the compressor starter capacitors also sold here on Amazon. I'm happy to have such value in such a cheap package. In reality, you can also use this for a sous vide controller. The only downside is that though the resolution is to .1 degree F, the control range is a minimum of 1 degree. If you wanted to hold exactly at 100 degrees, for example, it would kick on the heater at 99 degrees, and stop at 100, then kick back on at 99 degrees. One degree is the minimum range you can set. If you need any more narrow control band, I suggest you get a PID controller. For the vast majority of applications however, this can't be beat. The range is adjustable (on/off) to whatever you wish, but not less than 1 degree. It is adjustable to display C or F. It also has a setting to prevent "short cycling"... that is, kicking on, and off your compressor so often that it burns up faster. The setting puts a timer on the minimum time from when it last went off, to when it goes on, and visa-versa. For example, you can set it to not to cycle less than 3 minutes (factory default). The probe cord is about 6 feet, and the probe itself is plastic coated and just over 1/2 inch. It seems pretty responsive (you hold it in you hand and it warms up about 1 degree F per second, or faster). I hope you find this review helpful.

    I ordered two of these to build an incubator and hatcher. Instead I built a heated/cooled brooder first. The heater is a 100 watt radiant heat emitter for reptiles, and the cooler is a computer cooling fan. I have been very impressed by the functioning of the controller. It maintains its programming even after power outages. Mine was inadvertently rained on and was not affected. I'm not claiming it is waterproof - just lucky. When it got wet I was afraid that it would be dead, but it has continued to work just fine. I had a little difficulty figuring out how to program the unit. Once I reread the instructions several times, I finally understood that you have to store the value you've input by hitting the on/off button after you've set each parameter. The way you set the heating and cooling is to set your heat temperature upper limit pretty much like you'd expect. Then you set the cooling set point by choosing 1 to 30 degree differential as one of the menu choices. Say if you are hatching eggs and set the temperature to 100 degrees. You don't want the eggs to go higher than 102. Set the degrees of differential between heating and cooling to 2 degrees. That way when the temperature is below 100 the heat function will be switched on. Once the unit reaches 100 degree the controller will switch off the heat. When the thermostat detects that the temperature has increased more than the 2 degrees you selected then the cooling device will activate and remain on until the sensor detects a temperature below 102. The maximum difference between heating and cooling is 30 degrees. The minimum difference between heating and cooling is 1 degree. The temperature is displayed to tenths of a degree, so you can set heating set point at a temp of 99.5 degrees. There are two LED lights on the display marked heating and cooling, so you can tell at a glance whether the controller is in heating or cooling mode. The current temperature is displayed all the time. This thermostatic controller seems to very accurate. My quail chicks are very happy with their new brooder.

    5.0 out of 5 stars Great replacement/upgrade for traditional mechanical fridge thermostat.
    Reviewed in Canada on December 10, 2022
    Great replacement/upgrade for traditional mechanical fridge thermostat.

    The mechanical thermostat on my fridge failed. Original piece was no longer available at a reasonable price, so I got a universal replacement. It seemed to work, but had a terrible hysteresis....meaning it would run the compressor until the fridge was cooled to the desired 2 degrees C, but would only turn the compressor back ON again when the fridge temperature rose to a balmy 8 or 9 degrees C. I found this wide margin between compressor OFF and ON temperatures to be unacceptable.

    I stumbled upon this Inkbird ITC-1000 unit by accident and was skeptical at first but decided to give it a try.

    VERY VERY pleasantly surprised !!!

    It is compact, and once you understand the programming functions and parameters it is very easy to use. I had to read the instructions a couple of times but after that it was a breeze.

    Wiring the unit is simple. Power cord, sensor, and in my case, 2 wires to the compressor control wires. I tested the compressor running current and it's about 2 amps.....the ITC-1000 relay contacts have a spec of 10 amps, so no problem there.

    The unit has been running without issues for a few weeks now. I have set the temperature ("ts" in the programming menu) to 2 degrees C , and the delta ("ds" in the programming menu) to 2 degrees C.

    So, the compressor will run until the fridge cools to 2 degrees C, then switches OFF. It switches ON again when the temperature rises to 4 degrees C, which is "ts" plus "ds", and starts to cool again.

    Overall this is an excellent unit and is cost effective as well. HIGHLY RECOMMENDED.

     Remarkable product for the price. Easy to use and install. We have a Sub-Zero Wine Cooler. The analog thermostat is no longer available from Sub-Zero or the thermostat manufacturer. I bought this controller, tested it and it worked perfectly. It’s actually a tremendous upgrade. Now I can control the temperature to within 1° and I can see what the temperature is at any time. Before I just had a rotating knob analog thermostat that failed every few years. Note that I had to cut the steel mounting bracket and front cover to install this digital thermostat. It needs AC power which can be either run separately or spliced in from line in to fridge. Another great feature is that you can set a temperature delta and a compressor delay. Temperature delta means that if you set a delta of 3° for example, and set target to 50°F it won’t turn on until it hits 53°. A compressor delay means that you can set a delay so that the compressor doesn’t burn out by cycling on and off too quickly. Both settings will reduce energy and extend life of compressor potentially.
