    The temperature display is bright and easy to read. The installation was easy if you know how to strip wire ( you will need an old plug/line -- I took one from a broken dvd player to connect for power). Everything simply connects to screw terminals in the back of the unit. The unit is not in English, but comes with instructions in English, which are fairly easy to follow. The operation is simple, as long as you read the instructions. I would buy again and I recommend this item for general temperature measurements and or device control such as a fridge. Mine will be used to trigger a camera when the basement temperature in my house falls below a certain level.

    I bought this for a keggerator project and am very happy with it. . A lot of folks buy the Johnson controller. It works great, but is about $95. This one is around $25. It took me about 20 minutes to wire it up to convert a chest freezer into a keggerator. If you're strictly a plug & play kind of person, get the Johnson. If you can do basic wiring and read the instructions, you'll have no problem getting this to work well. I like the digital read-out with temps in fahrenheit, not celsius, to 1/10th degree.

    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.

    After reading reviews of both this product, the Docooler Digital Temperature Controller and the similar STC-1000, I realized that this unit does exactly what I want: a unit that I can re-purpose easily to either heat or to cool, with one power plug and one receptacle for the plug on the unit I am controlling. I use this to control either heating my bread dough to its optimal proofing temperature, or cooling my beer to fermentation temperature. I never need to have a set-up that can be configured and then switched between heating and cooling, like your home heating/air conditioning. Thus, I only need one receptacle to plug into, not two, as would be wired with the STC-1000 units. The good news for those buying this now is that the instructions are much clearer, including the wiring diagram. I did get mixed up with the low and high limits, thinking that I needed to set them to control the temperature, but the unit does that via the parameters, so all you do is set the target temperature, which comes up when you press “set”. I was pleased that the connection terminals accepted two 16 gauge wires, so the trick I used with my earlier controller worked fine: I took a 12-15 foot extension cord, cut it in half, and used the plug/male half to power the unit and supply the ‘hot’ side of the relay, and wired the receptacle/female half to accept the switched hot from the relay and get neutral from the plug half, via the shared neutral input on the controller. I only needed one jumper wire between the hot into the controller and the hot side of the relay, as pictured both on the unit and in the instructions. As always, consult someone with good experience with electrical wiring to confirm that you have hot and neutral wired correctly.

    J'ai acheté ce regulateur pour équiper un vieux chauffage dont le bilame avait un énorme hysteresis. Il remplit bien sa fonction, pas bien compliqué a connecter, s'encastre proprement et solidement dans la fenetre que je lui ai découpé. L'hysteresis minimal est de 1°, pour réguler la temperature d'une chambre ca aurait été préférable de descendre un peu en dessous de ça mais malgré tout c'est très convenable pour ce tarif. J'enlève une étoile parce que j'ai une odeur de plastique chaud lorsque le radiateur est en service alors que le régulateur est positionné en dessous, je pense que le type de plastique utilisé ne supporte pas du tout le moindre rayonnement.

    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.

    Excellent product dead on accurate!! I use this for amphibians I have. They are very temperature sensitive, if temp of there water get to or above 24c (75) it can kill them. I've been using this unit for a little over 2 years now and it has not failed. it controls the custom built chiller and water pumps to a 500 gallon tank{highest temp reached was 21c (70f)and this was during our rainy season and temp exceeded 41c (105f)}. with 42 Ambystoma mexicanum "Axolotl (pronounced Ax-oh-lot-ul)" and around 500-800 feeders

    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").

    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.

    There are many applications for this great controller. I used this device to control up to a 700 watt heater (120v) to keep pipes from freezing. It is a great and cost-effective controller. However, you need to be well-versed in electrical work to make sure the wiring is done correctly and safely. Also, the instructions are pretty worthless (but the settings are intuitive) - hence the four stars. So for 120v applications, if you are not sure about your skills at residential wiring (or have a friend who is), then you might want to pass on this controller and pay about $70 more for a pre-wired one.

    This was purchased with low expectations hoping for a temporary solution on my boiler. True to expectation, it is Chinese made. Unexpected reward, all instructions are in English (albeit poor grammar)! Instructions are detailed enough to make the device work as I need it. While polarity is not noted in the instructions nor on the casing, seems irrelevant as device works regardless of +/- wiring. Useful features include user-programmable temperature/time delay, heating/cooling. Does not switch to Fahrenheit and only controls heating or cooling, not both. So pleased I purchased a second unit.

    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 ...

    actually works pretty damn good, it was confusingly simple to program given what I'm used to, i definitely muttered "that's it?..... that's all the parameters?" when i set it up and went through it three times just to make sure... the algorithm actually regulated output signal quite well and was able to maintain temperature on the automatic scalding system i used it for. held the water at 145 degrees all day without an issue... better than some of the $300 name brand controllers i've used at work that were a nightmare to program! hahaha!

    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.

    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.
