Disclaimer: I am posting this as a guide for anyone else like me that has 0 electrical experience but might have played with other crafts in the past. Not responsible for electrocution. This is my interpretation of many other blogs, pictures, and with the supervision of family electricians. My device is working and is safe. Materials a chest freezer, preferably a 5-ish cubic ft one. (will not suffer any damage) 3 prong extension cord, preferably a short 6 or 9 ft thermostat from Amazon- remove the back cover to work by taking out the screw wire strippers electrical tape awesome scissors tiny flathead screw driver 1. Pull the thermometer wire in 2 about a half inch (came with thermostat) 2. put one end of each of the split wires into ports 5 and 6 3. Use the tiny screw driver to clamp down on the wires 4. CUT THE EXTENSION CORD IN HALF (yes, it's scary and weird) 5. Place the pronged end to your right and the female (receptor of a plug) end to the left 6. strip the outer extension cord off about 6 inches from the cut on both sides, exposing 3 wires on each side (working with only that 3 inch piece you just cut) 7. cut about 3 inches of black wire from the right side. 8. use the wire stripper tool or scissors to expose the copper wire right in the middle 9. work the black wire apart on both sides so that about 1/4 inch of wire is exposed in the middle 10. strip off 1/4 inch of black rubber, exposing the wire on either side 11. twist the ends tight and clamp them into ports 1 and 3 at this point you have the thermostat with 3 wires in the ports and 3 ports free 12. pick up the pronged side of the extension cord 13. strip off about 3/4 inch of the rubber from the black cord 14. wrap the exposed copper of the black wire from pronged extension cord around the exposed middle of the 3 inch strip that is secured into the thermostat. twist it around itself 15. use electrical tape to cover any of the exposed wire on the black (now y-shaped) wire that is attached from the pronged side to the thermostat 16. strip off 1/4 inch of the only free black wire left (the one on the female side of the extension chord) 17. twist, insert, and secure the free black wire into port 2 18. Strip off 3 inches of each white wire from both sides of the cut extension chord 19. twist together the 3 inches of exposed wire creating a Y facing away from you 20. wrap the exposed wire with electrical tape except for the last 1/4 inch of this joined wire. 21. insert the tip of the exposed /wrapped white wire into port 4 and secure. At this point you have two cut green wires, and all of the ports have been filled. You are wondering what to do with the last wires. 22. strip off an inch from both sides of the green wire. 23. twist the green wires together to "rejoin" them in a strait line. 24. Cover the twisted and exposed green wire with electrical tape. 25. cover anything copper that's still exposed with more electrical tape. 26. make absolutely sure NONE of the copper wire from black/white/green is exposed or touching any other color of wire other than it's own color. NO CROSSING STREAMS (ghostbusters) You're done assembling! Plug the pronged end of your extension cord into the wall Insert the thermometer into the chest freezer. Plug the freezer into the female end of your extension cord. Play with the settings till its on "cool" instead of "heat" Use electrical tape to keep that sucker on the lid. put it at a temp you want. Watch significant other be in awe of you!

Using this to control temperature in my hot tub. Original mechanical micro switch thermostat kept temp within 4-5 degrees, which is unacceptable for a hot tub, but this sits at 102 F and rarely varies 1 degree. It has a 10 amp output relay, so I wired it to a 50 amp contactor (A/C compressor relay) and then to my 22 amp heating element. Added bonus, I have a nice LED readout showing my hot tub temperature. Slow delivery, but for 99 cents to ship from China to my door, so what. I bought a second on and use it for an accurate thermometer.

Aside from the somewhat cryptic instructions, it works perfectly. Hookup is easy. I had to adjust the temperature offset about 7 degrees to make it accurate, but once I did, it's been dead-on. I like that the hysteresis is adjustable. I'm using it on a small chest freezer that I use as a refrigerator. Increasing this setting to 4 degrees reduces the compressor cycling.Mounting options are pretty limited, unless you're pretty good and metal fabrication. Since this set up runs on solar power, having the temp displayed all the time is a nice confirmation that all is good.

Ordered this to control some fans in our rabbit barn. Needed reasonable accuracy -- the analog ones we've tried varied from day to day by 5 degrees or more. Received the controller before they said I would (does ship from China). The instructions are readable but not the clearest. Thanks to several reviewers who have additional helps on operating. Wiring is fairly simple -- wire the load to two contacts and provide power to two contacts and put the sensor to the last two. The first unit I received worked only in heat mode -- would not activate in cool mode. I contacted seller through Amazon and they promptly responded and determined unit was defective. They happily sent another unit with no hassle. Their customer service through email was very good though it takes time to cycle emails back and forth -- they seemed to reply within a couple of business hours. They sent me a second unit which I installed and it worked great. Been working now for two weeks with no hitches or problems. Seems to be very accurate +/-1 degree. Display is easy to read. Turns our fans on over 78 and off below 78 exactly as we need. For the money you are not going to find a better thermostat. Summary: great product which seems to work well; though the 1st one was defective they promptly replaced it; shipping was as stated (looks like they may have just gone prime so shipping might be faster now); works great as fan controller.

Good so far. I am using it to keep my minnows heater at 60°F The directions are in Chinese so the only way I knew was to do was by someones very helpful review. I ordered the Celsius only one. You need to hold the set button to choose either to heat or cool and set the temperature range. There is a setting to vary the temperature by how many degrees. You can also delay the time before it turns on but I didn't use that. At first I had it at .1° but the heater kept turning on and off very quickly so i changed it to .2°. To change the temperature you want it to be at you have to push the set button once fast than use the arrows to put it where you want it to be set. Now I have a bunch of wires I'll need to build an enclosure.

I use this for sous vide cooking, which requires precise temperature control. When I started cooking with it I would notice that my steaks were much more done than they should have been for a given temperature. I bought a digital thermometer to test, and sure enough, this unit was of by 5 degrees C (9 degrees F). I though I was getting a 131 degree cook and it was actually 140. Fortunately the unit has a built in temperature offset capability, so I was able to adjust it correctly. Make sure you calibrate yours before you start cooking with it, otherwise works great!

Product works well but it only lasted a year and a half before the contacts became frozen, and the timer was essentially stuck in the ON postion. This was particularly bad because I have it installed in a restored Coca-Cola cooler. Since it never turned off at 30F, the cooler got so cold it froze all the soda in the machine, and every single can exploded! It was a huge mess to clean up, and it took me a minute to realize how it even happened. I've purchased another one because the machine has been modified to fit this model specifically. Hopefully the next one lasts a bit longer. I have also noticed that the outer casing has been redesigned in the last year, with English replacing a large majority of the text on the unit itself. The instructions still suck though.

I use the digital temperature controller to monitor and control my aquarium temperature. It is very easy to set and very precise. I have ordered another one for my second aquarium. I will order one more to mix hot/cold water for water change. The controller fits perfectly into a $0.6 plastic electrical box (B122A size), which is available in any home improvement center. I spend less than $3.00 for extra material to build a very nice controller box - see picture. Many people complained about the poorly written manual for the controller. I would like to share my knowledge about this controller. I hope this Manual will help. Manual for MH1210F 10A 110V Digital Temperature Contoller with Sensor - NTC 77 Fahrenheit=10K B3435. Display Codes (Adjustable Parameters): HC H/C Heating or Cooling mode. CA -1.5 Temperature Calibration. -1.5 is my setting (default at 0.0 ˚F) which decreases measured temp by 1.5˚F. At the default 0.0 setting, my controller reads 78.5˚F and a good thermometer reads 77˚F; I entered -1.5˚F in CA, now the controller and the good thermometer have the same readings. PU 00 Delayed cooling start time (minutes). Minimum off time to protect cooling compressor. HA 194 Highest operating temperature limit (default at 194˚F). When exceeded the device will switch off the load and blink HHH. LA -58 Lowest operating temperature limit (default at -58˚F). When exceeded the device will switch off the load and blink LLL. CP 01 Temperature Differential Setting. 01 is my setting (default at 02 or 2˚F). Turn on at 1˚F below temperature setpoint. If my temperature setpoint is 77˚F, heater is turned off when temperature reached 77˚F and turned back on when temperature dropped to 76˚F. The aquarium is always between 76˚F and 77˚F, a 1˚F temperature differential. Set: Press once to change temperature setpoint. Then press once return to display measured temperature. Hold for 3+ seconds to access parameters setting menu. Press "Set" to accept and exit settings menu after configuring a parameter. Rst: Press once to exit current setting. Press and hold 6+ second to reset to factory defaults. UpArrow: Increases settings. When not in parameters setting menu, this sets the heat/cool setpoint. Hold for 2+ seconds to auto advance. DownArrow: Decreases settings. When not in parameters setting menu this sets the heat/cool setpoint. Hold for 2+ seconds to auto advance. DownArrow: From main display of measured temperature, hold for 6+ seconds to lock parameters from being changed (display shows "OFF"), temperature setpoint is NOT locked and still can be changed; hold another 6+ second to release from lock mode (display shows "ON").

It took some experimenting , but I got this controller working super. The instructions need some work for clarity. After reading several times and trying different things the process begins to fall in place. The hook up diagram was the easiest of all. I used some existing power cords and I started by cutting the receptacle end off and using the cord for the power hook up. Now you can use the receptacle end for the load hook up. One more short wire from power to load and you are there. Just follow the diagram without any deviations and it works. The display is in bright large easy to read numbers and letters. The project I'm using this on requires the controlling of a set high temperature to click on and a low temperature to cut off. It took some time to get the controller working right, but it's doing a good job with very precision settings. Looks like this controller can be used in a variety of different ways for other applications. Ten amps @ 120 volts will be more than enough for my project.

This one displays in Fahrenheit. I use this for sous vide cooking. Unlike the STC-1000, this model has only one relay. It can be used to control either heating or cooling. It powers up in the heating mode by default. Changing to cooling mode is programmed via the "Set" key. The instruction is not well written, but it is not that difficult to figure out how to program the unit. I put this controller into a 4.7x4.7x2.2in Hammond 1591 USBK ABS plastic project box, which is also available from Amazon. It fits nicely inside this box, with room for a Amico 3 pin power socket for plugging in the load. It is very easy to wire up. The relay is rated at 10A, so I use a 16 AWG power cord as a supply cord. The temperature sensor cord is a bit flimsy, but it works. For $17, I can't complain!! Can easily replace this 10K NTC sensor if broken. I already have a Johnson Controls A419 controller, but I need another controller. This is a much lower cost alternative. It is so inexpensive, I also put together another unit for a friend.

I was looking for a simple thermostat to control a light bulb in my sourdough proofing box. This controller is perfect for this application. It is possible to program several settings (heat/cool mode, temperature hysteresis, min/max temperature range, delay start and temperature calibration offset.) Of course the temperature set point is settable as well and it remembers everything when powered off. It even provides a way to lock the menu settings so they aren't accidentally changed. I think the price for this digital controller is really reasonable as well as the shipping cost - I paid $16 for the product delivered to my door. The estimated delivery was way out (month and a half), but it actually arrived in about two weeks. The only downside (hence the 4 stars) is the manual. While it provides the information sufficiently needed to connect the controller, it takes some effort to understand the text for operation. This isn't a big minus since the controller is quite simple to use and program and you can get the information you need from the manual and discover the rest by experimentation. I did write my own manual for future reference, rather than try to figure it all out again.

Great product. It measures by .1 or .2 degrees, you can calibrate it. I hooked up the sensor with about 40' of cat5e cable, wasn't sure if that would affect the temperature reading but it worked fine. Measuring solar panel temperature, will be using it to remotely turn on/off a cooling fan to cool the panels in the hot sun. Very versatile. Plugs in to 110vac, and only uses 1 watt of power if the relay is off, 2 watts if it's on. Bright clear display. Retains settings after power is unplugged. It's actually a little smaller than it looks, but a good size. Only problem is that the pinouts are marked in Chinese, so you have to refer to the instructions for hookup. Use a Sharpie to mark them in English. Also could be easily used as a simple thermometer at this price point. It updates every few seconds. Oh, and the probe is super-sensitive to temperature changes. If you simply grab the sensor for 1 second, the temperature will jump by 3-4 degrees due to your body temperature.

Module powered up and functioned immediately. I built a box for it and associated power cabling, all went well on first assembly. I'd recommend socketing the temperature probe - I used a mini headphone jack on my project box. If you're not clear on the settings: when used for heating, you set the MAXIMUM temperature, where the relay cuts off, and the DIFFERENCE in degrees between the max and the minimum temperature. So for my use I set it at 38 degrees max, and a difference of 4 degrees: the relay turns on at 34 degrees (38-4) and turns off at 38 degrees). I wish I could deduct a half point for the directions, they are OK but a bit opaque (a medium quality translation, not horrible but needs work to explain things so a less experienced person could use it easily).

Je cherchais une solution pour réparer ma tireuse à bière, voilà qui est fait. Le contrôle de la t° de ma tireuse à bière ne fonctionnait plus, alors que le groupe de froid est vraiment excellent. Ce contrôleur lui a éviter de partir à la poubelle. L'avantage de ce produit est qu'il est livré complet avec sa sonde de T°. Relativement compact, un afficheur de taille et d'intensité parfaite, il est relativement facile à configurer à l'aide de la notice fournis. Il aurait été plus aisé d'avoir cette dernière en Français, mais même avec mon petit niveau en Anglais j'ai pu le paramétrer facilement. De plus il est équipé d'un système qui permet de clipser le cache de la façade, ce qui permet de l'intégrer facilement dans un petit boitier, un meuble ou n'importe quelle installation. Il est capable de contrôler autant une plage de froid (frigo, congélateur, tireuse à bière, ...), qu'une plage de chaud (couveuse, aquarium, ...). C'est le 1er paramètre à sélectionner dans le menu. Le mien est en place depuis presque 1 mois et fonctionne parfaitement. A voir la fiabilité dans le temps ...

Réception dans les 48 h et en très bon état .Surpris car on me donnait un délai de 15 jours. je viens de le raccorder pour une utilisation de chauffage avec un ruban autoregulant en exterieur afin d'éviter que mon palmier ne subisse trop de très basse température.Fonctionne aux petits oignons. J'ai comparé la sonde avec un thermomètre digital qui mesure aux dixième.Et la je m'apercois qu'il me rend une température équivalente de l'ordre du dixième de degré .Magnifique. La doc est en anglais mais il est facile de la trouver sur internet. Bon maintenant je ne sais pas dans le temps ce que ca va donner mais aujourd'hui j'estime avoir fait un très bon investissement. J'espère que ces infos pourront en aider d'autres.

Finally have been able to install my temperature controller. It works as advertised and nothing more. Understand that this does heating and cooling but only one at a time. So you have to set and reset to the heating or cooling mode to which it opens the thermo-coupler differently. In the cooling cycle it does give some delay to save the compressor if you use a fridge or freezer. I was prepared with different instructions but actually the enclosed ones were easy to follow as well. Just some basic knowledge of electricity is needed, nothing complex. In my case I just added the thermo-coupler to an outlet in which I add a freezer or heating device such as an old lamp. I just wish there was an easy case to build this in. Oh yeah, I have no idea what the orange brackets do and if they even come off as I would want. I assume these are to build the device into a case and to press against the back to keep it in.

Sur le schéma de la notice l'objet "LOAD" désigne la place de votre appareil. Par exemple pour moi c'était un frigo. Dans le schéma je remplace le mot "LOAD" par les mots "LA PRISE SECTEUR DE MON FRIGO". Le reste de la notice se comprend aisément par quiconque de vos voisins ou amis ou membres de votre famille ayant fait même un tout petit peu d'anglais. Bref j'ai réglé le thermostat défectueux de mon frigo à fond. J'ai scotché le nouveau contrôleur à l'extérieur sur la paroi du frigo et j'ai mis la sonde à mi-hauteur à l'intérieur en enfonçant légèrement la tôle pour laisser passer le fil de sonde sans géner le joint de porte. J'ai fait le montage et les réglages et "Nickel Chrôme" le frigo fonctionne mieux que jamais. Ce thermostat est de haute précision, de quoi garantir une hygiène irréprochable.

Unlike some other very similar offerings here on amazon, this unit can only be set up to heat -or- cool. If you are looking for a solution to be able to do either on the fly without reconfiguration, this is not your item. (one is branded as "Elitech All Purpose Temperature Controller" 2-relay, but there are others). That other item is virtually the same price, the manual is in [better] english, and the contacts come labeled in english as well. Other than the single-relay and abysmal english, though, this isn't a bad purchase. (I even submitted part of the manual on this item to engrish dot com! it's that good!)

Bought this for use in my fermenting refrigerator. Search google for wiring instructions, there are better ones out there than what's provided with the controller. It's rather simple to wire up and get working and so far it's made the single biggest difference in my beer brewing. I'm VERY happy with this cheapo solution. There are a couple of things to note: 1. This is a single stage, meaning it can only turn on one outlet. So in brewing, it's for turning the fridge/freezer on. If you need to regulate the temp even closer, you'll have to get the STC1000 which displays in Celsius only, but can also turn on a lightbulb or something to heat when it gets too cold. This obviously gives you much more precise control. I live in Florida where I only need it to cool, so I'm good there. 2. There's a 5 or so degree window in it's accuracy. In other words, if you want it to operate at 65 degrees, it won't kick on until it gets to 68, then it will cool down to 63 before turning off again. No big deal for most, but again, if you demand absolute accuracy.... Overall and for the price, I'm very pleased.
