I made my own incubator using this, it works very well. There was another review on how to wire this device but you can also YouTube it.

I will definitely purchase another if I find a need for another temperature control device.

I bought 2 of the temperature controllers, one for outside air temp and one for the project temp.
The units don't fit in a 2 1/2" deep project box, there's a plastic wire gutter in the back that takes up an extra 1/2" of space for the wires. After removing that wireway, it still didn't fit because the thickness of the wires(16 gauge, stranded) were pushing against the back of the box. I had already bought the box and didn't want to return it which would have postponed the project by a week at least.
Finally I decided to put a 1/4" spacer made from 1/4" plastic sheet on the front of the box to pull the units out and give room for the wires in the back of the units. It took some efforts to cut the template, but it worked.
The units are fairly easy to program if you can be patient with the Chinglish. Press and hold the "S" button for 3 seconds to get to the variables. Then press "Down" button to get to the variable you want to change then press "S" again to get the numbers for that variable. Be sure to save your change by pressing the button above the "S", it's some kind of symbol that doesn't make sense.
One of the units is a little slower to update but eventually the 2 units catch up with each other.
Be sure to calibrate the unit, but you'd need another temperature device that you trust to match with. In my case, I had 2 units that they are now matching each other but they are different than the house temperature indicator. When you have several temp indicators they all tell you different numbers.
Hopefully in the long run the units won't fail, we will see, but they're pretty well made.

Worked great as a replacement for a freezer part that was no longer available. Works perfectly, and is super adjustable.

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 purchased the ITC-1000F digital temperature controller to replace a failed mechanical controller in a wine cooler. Doing the research, I read many reviews, especially the one and two stars. I was concerned that this might not be a long term solution but at the price point, it was worth the risk.

Thanks to Amazon Prime, I received the device a day earlier than expected. It was packaged well and appeared to be well constructed for such a low price. The part I was replacing cost about $150.00 and this cooler has has had three of these in the last ten years!

The instructions that came with the unit were poorly written. In fact, there was a supplement that showed a different wiring diagram than what is printed on the unit. Before installing the unit into the cooler, I wired it temporarily to make sure that it worked correctly. The mechanical thermostat had two wires as it was a switch. I found the line wire and the load wire. These were connected to terminals one and two with jumper wires to 7 and 8, which were for the cooling mode. The temporary connections turned on because the temperature was much higher than the set temperature; cooled the cooler down ;and then shut off the compressor when it reached the set point. SUCCESS! After this, I cut a hole into the cooler grill to mount the unit and wired it for the permanent installation. By the time I completed this, the temperature was several degrees above the set point. I turned the unit but the compressor never started. FAILURE!

I contacted Ink-Bird at the "support" and "cs" email addresses and gave them detailed information on the installation and the failure. Even though the website states they would try to respond in 24 hours, I did not hear back until the third day and they only sent me a wiring diagram while ignoring my questions. By then, I diagnosed that the switch on the 7&8 terminals was not working.

THANK YOU AMAZON! I contacted Amazon, explained the problem and they had a replacement unit to me in one day!

I wired the new unit temporarily and it worked immediately. This time I left it this way until the unit had cycled several times until the next morning. I installed it permanently and it has run perfectly for four days. SUCCESS!

The temperature controls are accurate and needed no calibration. The settings are precise and the differential settings keep the compressor from being overworked. If the unit lasts, I will be really pleased.
